Description

本発明は、ナノインプリントのモールドとして使用可能な微細構造体の製造方法に関するものである。   The present invention relates to a method for manufacturing a microstructure that can be used as a mold for nanoimprinting.

従来微細構造体の作製方法としてはフォトリソグラフィー法が用いられてきたが、プロセスが長くて複雑であるうえ、微細化にも限界がある。これに代わる技術の一つとしてナノインプリント法が用いられている(例えば非特許文献1参照)。   Conventionally, a photolithography method has been used as a method for manufacturing a fine structure. However, the process is long and complicated, and there is a limit to miniaturization. As one alternative technique, a nanoimprint method is used (for example, see Non-Patent Document 1).

ナノインプリント法は、作製したい構造体に応じた凹凸を持つモールドを作製し、これを基板に圧着することで圧痕を作製し、この圧痕を元にして構造を作製するものであり、簡便なプロセスでありながら微細な構造作製が可能である。ナノインプリントで用いられるモールドとしては、例えばリソグラフィー法を用いて形成しているSiC又はSiO2 製のものが報告されている(例えば特許文献1等参照)。 The nanoimprint method is to create a mold with irregularities according to the structure to be manufactured, press this to the substrate to create an indentation, and create a structure based on this indentation. It is possible to produce a fine structure. As a mold used in nanoimprinting, for example, a mold made of SiC or SiO 2 formed by using a lithography method has been reported (see, for example, Patent Document 1).

しかし、リソグラフィー法を用いてモールドを作製する場合、描画工程やドライエッチングの工程などを経るため、モールド作製に必要な工程が複雑であり、作製する構造が微細になるほど、面積が広いほど、突起形状が高アスペクトであるほど、加工には長時間を要する。このため、モールドが複数個必要なときは、マスターとなるモールドを作製した後にめっき法などによりレプリカを作製する。   However, when a mold is manufactured using a lithography method, a drawing process, a dry etching process, and the like are performed. Therefore, a process necessary for the mold is complicated. As a structure to be manufactured becomes finer, an area increases, The higher the shape, the longer it takes to process. For this reason, when a plurality of molds are required, a replica is produced by plating after producing a master mold.

例えば、マスターとなるモールドを電子線ビームリソグラフィーなどにより作製した後に、このモールドを樹脂に圧着し、樹脂を硬化したのちにモールドを剥離する。モールドを反映する凹凸をもつ樹脂表面に無電解めっきの触媒を吸着させた後に無電解めっきを行い、無電解めっき膜の上に電解めっきを行った後に、めっき物を剥離する。これにより得られためっき物をレプリカモールドとして使用する方法が提案されている。(特許文献2等参照)

For example, after a master mold is manufactured by electron beam lithography, the mold is pressure-bonded to a resin, and after the resin is cured, the mold is peeled off. After the electroless plating catalyst is adsorbed on the resin surface having irregularities reflecting the mold, the electroless plating is performed. After the electroplating is performed on the electroless plating film, the plated product is peeled off. A method of using the plated product obtained as a replica mold has been proposed. (See Patent Document 2 etc.)

特許文献2に記載されている様に、マスターとなる構造体を樹脂に圧着し、これにめっきを行った後に剥離してレプリカを作製するプロセスにおいて、電解めっきを行う前に樹脂表面を導電化処理する必要がある。導電化処理の方法としては、スパッタや真空蒸着などの乾式プロセスと無電解めっきなどの湿式プロセスが用いられる。高アスペクト比を持つ構造体に対しては、樹脂に構造を転写した後に形成される凹部に対して付与する導電膜の膜厚の均一性を、更に向上することが求められる。   As described in Patent Document 2, in a process in which a master structure is pressure-bonded to a resin, and plating is performed on the structure, and then a replica is made to make a replica, the resin surface is made conductive before electrolytic plating. Need to be processed. As a conductive treatment method, a dry process such as sputtering or vacuum deposition and a wet process such as electroless plating are used. For a structure having a high aspect ratio, it is required to further improve the uniformity of the thickness of the conductive film applied to the recess formed after the structure is transferred to the resin.

本発明によれば、ナノインプリント用モールドとして使用可能な構造体を容易に製造することができる。   ADVANTAGE OF THE INVENTION According to this invention, the structure which can be used as a mold for nanoimprint can be manufactured easily.

以下、本発明の実施の形態について述べる。
ナノインプリント用モールドとして使用可能な突起を有する構造体を、無電解めっきの触媒を含む樹脂を用い、めっきにより製造する方法について示す。
Hereinafter, embodiments of the present invention will be described.
A method for producing a structure having protrusions that can be used as a mold for nanoimprinting by plating using a resin containing a catalyst for electroless plating will be described.

このため、無電解めっき反応の触媒を含有する樹脂に構造体を圧着し、樹脂表面に構造体の転写パターンを作製後、転写パターンを持つ樹脂表面に無電解めっきを行い、更に必要に応じて電解めっきを行った後にめっき物を樹脂より分離することで達成できる。   For this reason, the structure is pressure-bonded to a resin containing a catalyst for electroless plating reaction, a transfer pattern of the structure is produced on the resin surface, electroless plating is performed on the resin surface having the transfer pattern, and if necessary This can be achieved by separating the plated product from the resin after electrolytic plating.

無電解めっきは、金属塩、錯化剤、還元剤を主成分とする混合溶液において、還元剤の酸化還元反応により生じる電子を金属の析出反応に利用するものである。触媒活性な表面で選択的に反応が起こり、析出する金属が還元剤の酸化反応に触媒活性を示す場合には連続的に金属析出反応が進行する。   Electroless plating uses electrons generated by a redox reaction of a reducing agent in a mixed solution containing a metal salt, a complexing agent, and a reducing agent as main components for a metal precipitation reaction. When the reaction occurs selectively on the catalytically active surface and the deposited metal shows catalytic activity in the oxidation reaction of the reducing agent, the metal deposition reaction proceeds continuously.

本発明に使用できる突起を有する構造体の材質としては、Si,SiC,SiO2 や金属、セラミック、プラスチック、ガラスなどを用いることができる。構造体の高さは一定でなくても良い。構造体を樹脂へ圧着、剥離後に、構造転写部に触媒が露出可能なように樹脂厚を制御していれば無電解めっきは析出が可能であり、めっきによるレプリカ構造が作製できる。 As the material of the structure having protrusions that can be used in the present invention, Si, SiC, SiO 2 , metal, ceramic, plastic, glass, or the like can be used. The height of the structure does not have to be constant. If the resin thickness is controlled so that the catalyst can be exposed to the structure transfer portion after the structure is pressure-bonded to and peeled from the resin, electroless plating can be deposited, and a replica structure can be produced by plating.

樹脂を表層にコートするために使用される基板は、シリコン等の半導体、アルミニウム等の導体、セラミック、プラスチック、ガラス等が挙げられるが、これに限定されるものではない。樹脂が十分厚い場合には基板は無くても良い。   Examples of the substrate used for coating the resin with the surface layer include, but are not limited to, a semiconductor such as silicon, a conductor such as aluminum, ceramic, plastic, and glass. If the resin is sufficiently thick, the substrate may be omitted.

触媒を含有する樹脂として、ポリメチルメタクリレート(PMMA)、ポリカーボネート、ポリエステル、エポキシ、各種レジストなどが例として挙げられる。構造体を樹脂に熱圧着することで構造転写が可能である。また、石英の構造体を感光性樹脂に圧着後、露光により樹脂を硬化した後に構造体を剥離することで構造転写を行うことができる。   Examples of the resin containing a catalyst include polymethyl methacrylate (PMMA), polycarbonate, polyester, epoxy, and various resists. The structure can be transferred by thermocompression bonding the structure to a resin. In addition, after the quartz structure is pressure-bonded to a photosensitive resin, the structure is peeled off after the resin is cured by exposure, thereby transferring the structure.

樹脂は無電解めっきに対して活性を示す触媒を含有している。樹脂中に触媒を予め含有させることで、樹脂を基板上にコートした後に、粗化および触媒化を行うこと無く無電解めっきが可能である。   The resin contains a catalyst that is active against electroless plating. By preliminarily containing the catalyst in the resin, electroless plating can be performed without performing roughening and catalysis after the resin is coated on the substrate.

触媒としては、金属微粒子、金属を担持した微粒子、コロイド、有機金属錯体などを用いることができる。樹脂に触媒となる金属を結合させても良い。また、触媒となる金属を、スパッタや蒸着などにより成膜しても良い。   As the catalyst, metal fine particles, metal-supported fine particles, colloids, organometallic complexes, and the like can be used. A metal serving as a catalyst may be bonded to the resin. Further, a metal serving as a catalyst may be formed by sputtering or vapor deposition.

金属微粒子としては、Pd、Pt、Ag、Au、Fe、Ni等及びこれを主成分とする合金から成る微粒子を触媒として使用可能である。
金属を担持した微粒子としては、金属化合物や触媒金属イオン錯体などを表面に担持した微粒子があり、例えばアミノ基、カルボキシル基、クラウンエーテル基、イミダゾール基のような官能基を有するアルミナの表面に、パラジウムイオン、白金イオン、銀イオン、金イオン、鉄イオン、ニッケルイオン等をキレートさせた微粒子が挙げられる。これらの微粒子をめっき前に還元処理することで、無電解めっきに対して触媒活性を示す。
As the metal fine particles, fine particles made of Pd, Pt, Ag, Au, Fe, Ni and the like and alloys containing them as a main component can be used as a catalyst.
As the fine particles carrying a metal, there are fine particles carrying a metal compound or a catalytic metal ion complex on the surface, for example, on the surface of alumina having a functional group such as amino group, carboxyl group, crown ether group, imidazole group, Examples thereof include fine particles obtained by chelating palladium ions, platinum ions, silver ions, gold ions, iron ions, nickel ions and the like. By reducing these fine particles before plating, they show catalytic activity for electroless plating.

コロイドや有機金属錯体としてはPdを含むものが無電解めっきに適しており、パラジウム−スズ混合溶液がある。めっき前に還元処理することで無電解めっきに対して活性を示す。   A colloid or organometallic complex containing Pd is suitable for electroless plating, and there is a palladium-tin mixed solution. It shows activity against electroless plating by reducing treatment before plating.

触媒となる金属を結合した樹脂としては、樹脂に含まれるアミノ基、カルボキシル基、クラウンエーテル基、イミダゾール基のような官能基によりパラジウムイオン、白金イオン、銀イオン、金イオン、鉄イオン、ニッケルイオン、等をキレート化させた樹脂が挙げられる。樹脂をコートした後に、キレート化されたイオンを還元処理することで金属微粒子を得ることができる。   As a resin bonded with a metal serving as a catalyst, palladium ions, platinum ions, silver ions, gold ions, iron ions, nickel ions are added depending on functional groups such as amino groups, carboxyl groups, crown ether groups, and imidazole groups. , Etc. are chelated. After coating the resin, the metal fine particles can be obtained by reducing the chelated ions.

触媒としてPdは無電解めっきに対して活性が高いため、樹脂中に分散するのに特に適している。
触媒は樹脂全体に均一に分散していることが好ましいが、偏在しても良い。また、触媒含む樹脂上に、触媒を含まない樹脂をコートすることで、樹脂を2層化しても良い。2層化するときには、触媒を含まない樹脂層厚を、構造体突起部のうち最小の突起より薄くする。これにより、2層化した樹脂に構造体に加熱圧着時に、構造体の先端部のみが触媒を含む樹脂層に達することが可能となる。構造体の突起部は先鋭であることが好ましい。この後に樹脂より構造体を剥離すると、構造体の突起部に対応する孔や溝など樹脂凹部にのみ触媒が露出する。この後に無電解めっきに関する処理を行うことで、無電解めっきの初期段階では樹脂表面の凹部にのみめっきを行うことが可能である。その後、更に無電解めっきを継続することで凹部はめっき物で充填され、樹脂表層部でめっきが成長し連続膜となる。凹部がめっきにより充填されるまでは表層ではめっき反応が発生しないことから、凹部のアスペクト比が1を越えるような場合で、特に円柱又は円錐台状の孔構造をもつ構造体のレプリカ作製の場合においても、めっき未着の発生を抑制することができる。
As a catalyst, Pd is particularly suitable for being dispersed in a resin because of its high activity against electroless plating.
The catalyst is preferably dispersed uniformly throughout the resin, but may be unevenly distributed. Further, the resin may be made into two layers by coating a resin not containing the catalyst on the resin containing the catalyst. When two layers are formed, the resin layer thickness not including the catalyst is made thinner than the smallest protrusion of the structure protrusions. Thereby, only the front-end | tip part of a structure can reach the resin layer containing a catalyst at the time of thermocompression-bonding to the structure to the resin layered into two layers. It is preferable that the protrusion of the structure is sharp. Thereafter, when the structure is peeled from the resin, the catalyst is exposed only in the resin recesses such as holes and grooves corresponding to the protrusions of the structure. By performing a process related to electroless plating after this, it is possible to perform plating only on the concave portion of the resin surface in the initial stage of electroless plating. Thereafter, the electroless plating is further continued to fill the concave portion with the plated product, and the plating grows on the resin surface layer portion to form a continuous film. Since the plating reaction does not occur on the surface layer until the recesses are filled by plating, the aspect ratio of the recesses exceeds 1, especially when making a replica of a structure having a cylindrical or frustoconical hole structure. In this case, the occurrence of non-plating can be suppressed.

また、先端部が平坦な構造体を用いる場合には、触媒が樹脂の表面にのみ存在しても良い。樹脂表面にコートされた触媒は先端部が平坦な構造体により凹部底まで押し込まれ、先端部が平坦な構造体を剥離した後も凹部底に残留する。また、構造体を樹脂に圧着するときに表層に金属層が存在するため、圧着時に樹脂が構造体に付着しにくくなる。   Further, when a structure having a flat tip is used, the catalyst may be present only on the surface of the resin. The catalyst coated on the resin surface is pushed to the bottom of the recess by the structure having a flat tip, and remains on the bottom of the recess even after the structure having a flat tip is peeled off. Further, since the metal layer is present on the surface layer when the structure is bonded to the resin, the resin is less likely to adhere to the structure during the bonding.

無電解めっき浴としてはとしては、Ni、Co、Cu、Au、Ag、Pd、Pt等及びこれを主成分とする各種合金を析出可能なめっき浴を用いることができる。ここでの合金の例としてNi合金としては、NiP、NiB、NiSnP、NiWP,NiFeP、NiWB,NiCuP,NiCoP等を挙げることができる。ただし、めっき後に樹脂として剥離することで得られる構造体をモールドとして使用することを考えた場合、硬度が高い圧着時に変形しにくいので、NiおよびNi合金を用いることが望ましい。無電解めっき液に含まれる還元剤としては析出させる金属や合金に応じて、次亜リン酸ナトリウム(NaH2 PO2 )、ホルムアルデヒド(HCHO)、テトラヒドロほう酸ナトリウム(NaBH4 )ジアルキルアミンボラン(DMAB DEAB)、ヒドラジン(N24 )等を用いる。 As the electroless plating bath, there can be used a plating bath capable of depositing Ni, Co, Cu, Au, Ag, Pd, Pt and the like and various alloys mainly composed thereof. Examples of alloys here include NiP, NiB, NiSnP, NiWP, NiFeP, NiWB, NiCuP, and NiCoP. However, considering that the structure obtained by peeling off as a resin after plating is used as a mold, it is preferable to use Ni and a Ni alloy because the structure is difficult to be deformed at the time of pressure bonding. As a reducing agent contained in the electroless plating solution, sodium hypophosphite (NaH 2 PO 2 ), formaldehyde (HCHO), sodium tetrahydroborate (NaBH 4 ) dialkylamine borane (DMAB DEAB) depending on the metal or alloy to be deposited. ), Hydrazine (N 2 H 4 ) and the like are used.

構造体を厚くする必要がある場合には、無電解めっきの後に電解めっきを行っても良い。用いられる金属としては、Ni、Co、Cu、Au、Ag、Pd、Pt、Fe等及びこれを主成分とする合金等、電解めっき可能であればどのような金属でも良い。このとき、無電解めっき膜と異なる金属および合金を電解めっき膜として用いても良い。ただし、電解めっき膜の応力が大きいと、めっき中にめっき物の樹脂からの剥離の発生、樹脂からめっき物を分離した後に応力によりめっき物が変形する可能性などがあるため、めっき膜の応力はなるべく低いほど好ましい。低応力のめっき膜としては、例えばスルファミン酸Niを用いためっき浴から得られる電解Niめっき膜が挙げられる。スルファミン酸Niを用いためっき浴から得られる電解Niは硬度が比較的高いこともモールド作製のためのめっき浴としての使用に適している。   When it is necessary to increase the thickness of the structure, electrolytic plating may be performed after electroless plating. The metal used may be any metal as long as it can be electroplated, such as Ni, Co, Cu, Au, Ag, Pd, Pt, Fe, and an alloy containing the same as a main component. At this time, a metal and an alloy different from the electroless plating film may be used as the electrolytic plating film. However, if the stress of the electrolytic plating film is large, peeling of the plated product from the resin may occur during plating, and the plated product may be deformed by the stress after separating the plated product from the resin. Is preferably as low as possible. Examples of the low stress plating film include an electrolytic Ni plating film obtained from a plating bath using Ni sulfamate. Electrolytic Ni obtained from a plating bath using Ni sulfamate is also suitable for use as a plating bath for mold production because of its relatively high hardness.

次に、ナノインプリント用モールドとして使用可能な突起を有する構造体を、無電解めっきの触媒となる金属より析出電位が卑な元素を含む樹脂を用い、めっきにより製造する方法について示す。   Next, a method for producing a structure having protrusions that can be used as a mold for nanoimprinting by plating using a resin containing an element whose deposition potential is lower than that of a metal serving as a catalyst for electroless plating will be described.

前記、無電解めっきの触媒を含む樹脂を用いめっきにより製造する方法と異なる点は、樹脂に含有する元素およびめっき前に触媒を樹脂表面に析出する工程が追加されることであり、基板材質、構造体材質、樹脂材質および構造体の圧着方法、めっき方法などの工程は同一である。   The point different from the method of producing by plating using a resin containing a catalyst for electroless plating is that an element contained in the resin and a step of depositing the catalyst on the resin surface before plating are added. Processes such as the structure material, the resin material, the structure pressure bonding method, and the plating method are the same.

実施形態として、無電解めっきの触媒となる金属より析出電位が卑な元素を含有する樹脂に構造体を圧着し、樹脂表面に構造体の転写パターンを作製後、無電解めっきの触媒となる金属イオンを含む溶液に該樹脂を浸漬して触媒を樹脂表面に析出させ、転写パターンを持つ樹脂表面に無電解めっきを行い、更に必要に応じて電解めっきを行った後にめっき物を樹脂より分離することで上記の目的が達成できる。   As an embodiment, after a structure is pressure-bonded to a resin containing an element whose deposition potential is lower than that of a metal that becomes a catalyst for electroless plating, a transfer pattern of the structure is formed on the resin surface, and then a metal that becomes a catalyst for electroless plating The resin is immersed in a solution containing ions to deposit the catalyst on the surface of the resin, electroless plating is performed on the surface of the resin having a transfer pattern, and after further electrolytic plating is performed, the plated product is separated from the resin. The above object can be achieved.

無電解めっきの触媒となる金属より析出電位が卑な元素は、金属微粒子、金属を担持した微粒子、コロイド、有機金属錯体などの状態で樹脂に含有される。無電解めっきの触媒となる金属より析出電位が卑な元素を樹脂と結合させても良い。また、スパッタや蒸着などにより成膜しても良い。   Elements having a lower deposition potential than the metal that serves as a catalyst for electroless plating are contained in the resin in the form of fine metal particles, fine particles carrying a metal, colloids, organometallic complexes, and the like. An element having a lower deposition potential than the metal serving as a catalyst for electroless plating may be combined with the resin. Further, the film may be formed by sputtering or vapor deposition.

金属微粒子としては、Sn及びこれを主成分とする合金から成る微粒子を使用可能である。
金属を担持した微粒子としては、金属化合物や触媒金属イオン錯体などを表面に担持した微粒子があり、例えばアミノ基、カルボキシル基、クラウンエーテル基、イミダゾール基のような官能基を有するアルミナの表面にスズイオンをキレートさせた微粒子が挙げられる。また、スズコロイド、有機スズ錯体を用いても良い。樹脂中に含まれるアミノ基、カルボキシル基、クラウンエーテル基、イミダゾール基のような官能基によりスズイオンをキレート化させ、樹脂表面に構造体の転写パターンを作製後に還元処理を行ったのち、触媒となる金属のイオンを含む溶液に樹脂を浸漬することで触媒を樹脂表面に析出させても良い。
As the metal fine particles, fine particles made of Sn and an alloy mainly composed of Sn can be used.
The fine particles carrying metal include fine particles carrying metal compounds or catalytic metal ion complexes on the surface, for example, tin ions on the surface of alumina having a functional group such as amino group, carboxyl group, crown ether group or imidazole group. And fine particles obtained by chelating. Further, a tin colloid or an organic tin complex may be used. After the tin ions are chelated by functional groups such as amino groups, carboxyl groups, crown ether groups, and imidazole groups contained in the resin, a transfer pattern of the structure is produced on the resin surface, and then a reduction treatment is performed, which then becomes a catalyst. The catalyst may be deposited on the resin surface by immersing the resin in a solution containing metal ions.

無電解めっきの触媒となる金属より析出電位が卑な元素は、樹脂全体に均一に分散していることが好ましいが、偏在しても良い。また、無電解めっきの触媒となる金属より析出電位が卑な元素含む樹脂上に、無電解めっきの触媒となる金属より析出電位が卑な元素を含まない樹脂をコートすることで、樹脂を2層化しても良い。また、先端部が平坦な構造体を用いる場合には、無電解めっきの触媒となる金属より析出電位が卑な元素が樹脂の表面にのみ存在しても良い。   The element having a lower deposition potential than the metal serving as a catalyst for electroless plating is preferably uniformly dispersed throughout the resin, but may be unevenly distributed. Further, by coating a resin containing an element whose precipitation potential is lower than that of a metal serving as a catalyst for electroless plating, a resin containing 2 elements whose deposition potential is lower than that of a metal serving as a catalyst for electroless plating is used. It may be stratified. In addition, when a structure having a flat tip is used, an element having a lower deposition potential than the metal serving as a catalyst for electroless plating may exist only on the surface of the resin.

Si基板11の表面にスズ−パラジウムコロイド触媒13を含むPMMAをスピンコートにより200nmの厚さに成膜して熱硬化し、触媒を含有する樹脂層12を形成する。その後、フォトリソグラフィーにて作製した、200nmピッチ、線幅100nm、深さ100nmのSiC製ナノインプリント用モールド14を、触媒を含有する樹脂12に圧着する。圧着時にはPMMAをガラス転移温度以上に加熱し、モールド剥離時には室温まで冷却し剥離する。これによりナノインプリントでモールドの転写パターンが凹状構造15として樹脂表面に形成される。このとき、圧着を行った部分を含めてPMMA表面全体にスズ−パラジウムコロイド微粒子の触媒13が露出する。   A PMMA containing a tin-palladium colloidal catalyst 13 is formed on the surface of the Si substrate 11 to a thickness of 200 nm by spin coating and thermally cured to form a resin layer 12 containing the catalyst. Thereafter, a SiC nanoimprint mold 14 having a pitch of 200 nm, a line width of 100 nm, and a depth of 100 nm prepared by photolithography is pressure-bonded to the resin 12 containing the catalyst. At the time of pressure bonding, PMMA is heated above the glass transition temperature, and at the time of mold peeling, it is cooled to room temperature and peeled off. Thereby, the transfer pattern of the mold is formed as a concave structure 15 on the resin surface by nanoimprint. At this time, the catalyst 13 of the tin-palladium colloidal fine particles is exposed on the entire surface of the PMMA including the portion subjected to the pressure bonding.

圧着によりPMMA表面にパターン形成後に、基板を10%硫酸溶液に30秒間浸漬することでPdを触媒活性にして、下記の表1に示す無電解Ni−Pめっき液に浸漬する。これにより凹状構造15はめっき物で埋まり、PMMA表面に無電解めっき膜16が形成される。このときの無電解Ni−Pめっき厚を100nmとする。   After forming a pattern on the surface of PMMA by pressure bonding, the substrate is immersed in a 10% sulfuric acid solution for 30 seconds to make Pd catalytically active and immersed in an electroless Ni—P plating solution shown in Table 1 below. As a result, the concave structure 15 is filled with the plating, and the electroless plating film 16 is formed on the PMMA surface. The electroless Ni—P plating thickness at this time is 100 nm.

To do. The plated portions 16 and 17 after peeling have a structure equivalent to a structure having a line width of 100 nm and a depth of 100 nm at a pitch of 200 nm made of SiC, and this structure can be used as a nanoimprint mold.

Example 2
This example shows a production method in which a resin layer not containing a catalyst is formed on the surface of a resin containing a catalyst, and then a mold is pressure-bonded and peeled, plated, and a plated product is separated. FIG. 2 is a process diagram of a method for manufacturing a structure using a resin containing a catalyst for electroless plating according to the present embodiment.

エポキシ樹脂に塩化パラジウム5wt%、N,N−ジメチルホルムアミド20wt%を混合し、Si基板21の表面にスピンコートにより200nmの厚さにコートする。この後100℃で熱硬化し、還元によりPd微粒子が樹脂中に析出し、触媒23を含有する樹脂22を形成する。   An epoxy resin is mixed with 5 wt% palladium chloride and 20 wt% N, N-dimethylformamide, and the surface of the Si substrate 21 is coated to a thickness of 200 nm by spin coating. Thereafter, the resin is thermally cured at 100 ° C., and Pd fine particles are precipitated in the resin by reduction to form the resin 22 containing the catalyst 23.

触媒を含有する樹脂22表面に、PMMAを30nmスピンコートにより成膜した後に熱硬化して触媒を含有しない樹脂24を形成する。これにより樹脂表面に無電解めっきに対して活性を示さない層が形成される。   A PMMA film is formed on the surface of the resin 22 containing the catalyst by 30 nm spin coating and then thermally cured to form a resin 24 containing no catalyst. As a result, a layer that is not active against electroless plating is formed on the resin surface.

この後に、電子線ビームリソグラフィーにより作製した160nmピッチ、直径80nm、高さ100nmの円錐状構造を持つSiモールド25を、触媒を含有しない樹脂24に圧着する。これにより、PMMA表面に構造が転写され、160nmピッチ、直径80nm、深さ100nmのすり鉢状の凹状構造26が作製される。このときモールド25の突起は、触媒を含有しない樹脂24を貫通し、触媒を含有する樹脂22まで達することで、モールド25を剥離した後に触媒23が露出する。   Thereafter, a Si mold 25 having a conical structure with a 160 nm pitch, a diameter of 80 nm, and a height of 100 nm produced by electron beam lithography is pressure-bonded to a resin 24 not containing a catalyst. Thereby, the structure is transferred to the PMMA surface, and a mortar-like concave structure 26 having a pitch of 160 nm, a diameter of 80 nm, and a depth of 100 nm is produced. At this time, the protrusion of the mold 25 penetrates the resin 24 containing no catalyst and reaches the resin 22 containing the catalyst, so that the catalyst 23 is exposed after the mold 25 is peeled off.

その後、無電解Ni−Pめっき液に浸漬し、Ni−Pめっきを100nmの厚さに行い無電解めっき膜27を形成する。この後にスルファミン酸ニッケルめっき液により1μm厚のNiめっきを行い電解めっき膜28を形成したのち、樹脂22,24と被めっき物27,28を剥離する。剥離後のめっき物27,28は、Siモールドと同等の構造となっており、本構造体はナノインプリントのモールドとして使用可能である。   Then, it is immersed in an electroless Ni—P plating solution, Ni—P plating is performed to a thickness of 100 nm, and an electroless plating film 27 is formed. Thereafter, Ni plating with a thickness of 1 μm is formed by a nickel sulfamate plating solution to form an electrolytic plating film 28, and then the resins 22 and 24 and the objects 27 and 28 to be plated are peeled off. The plated products 27 and 28 after peeling have a structure equivalent to that of the Si mold, and this structure can be used as a nanoimprint mold.

Pd is deposited on the surface of the resin 32 to a thickness of 5 nm by sputtering to form the catalyst 33. Thereafter, a Si mold 34 having a columnar structure with a 160 nm pitch, a diameter of 80 nm, and a height of 100 nm prepared by electron beam lithography is thermocompression bonded to the resin 32 provided with the catalyst 33 on the surface.

その後、無電解Ni−Pめっき液に浸漬し、Ni−Pめっきを100nmの厚さに行い無電解めっき膜37を形成する。この後にスルファミン酸ニッケルめっき液により1μm厚のNiめっきを行うことで電解めっき膜38を形成した後、樹脂32と被めっき物37,38を剥離する。剥離後のめっき部37,38は、Siで作製した、160nmピッチ、直径80nm、高さ80nmのモールド34の構造と同等の構造となっており、本構造体はナノインプリントのモールドとして使用可能である。   Then, it is immersed in an electroless Ni—P plating solution, Ni—P plating is performed to a thickness of 100 nm, and an electroless plating film 37 is formed. Thereafter, Ni plating with a thickness of 1 μm is performed with a nickel sulfamate plating solution to form an electrolytic plating film 38, and then the resin 32 and the objects 37, 38 are peeled off.
