Description
このようなQFNでは、リードフレーム面積あたりの生産性を飛躍的に向上させることができる製造方法が、特に注目されている。その方法として、複数のQFN用チップをリードフレームのダイパッド上に整列させ、金型のキャビティ内で封止樹脂にて一括封止し、その後、切断によって個別のQFN構造物に分割することを含む製造方法が挙げられる。
つまり、リードフレームへの半導体チップの搭載後又はワイヤボンディングの実施後に耐熱性粘着テープをリードフレーム裏面に貼り合せることは、ハンドリングの面で実質的に困難であることから、まず、耐熱性粘着テープをリードフレームの裏面側に貼り合わせ、その後、半導体チップの搭載及びワイヤボンディングを経て、封止樹脂による封止を行った後、耐熱性粘着テープを剥離することが望ましい。
このような場合、リードフレームと下金型との間に生じるギャップによって、耐熱性粘着テープとリードフレームとの間、モールド部分の外周部をうまくクランプできずに樹脂漏れが発生する場合がある。
基材層と、該基材層上に積層された粘着剤層と、該粘着剤層に接触する剥離シートを備え、
前記基材層と粘着剤層との総膜厚が25〜40μmであり、
前記該剥離シートは、
剥離角度90±15°での剥離強度が1.5N/50mm幅以下、
剥離角度120±15°での剥離強度が1.2N/50mm幅以下、
剥離角度150±15°での剥離強度が1.0N/50mm幅以下又は
剥離角度180+0°〜180−15°での剥離強度が1.0N/50mm幅以下であることを特徴とする。
リードフレーム表面に搭載された半導体チップを樹脂封止する際に前記リードフレームの少なくとも一面に貼着され、封止後に剥離するために用いられることが好ましい。
前記粘着剤層が、前記基材層の片面上にのみ積層されていることが好ましい。
前記リードフレーム上に半導体チップを搭載し、
該半導体チップ側を封止樹脂により封止し、
封止後に前記粘着テープを剥離する工程を含むことを特徴とする。
さらに、粘着テープの貼着から樹脂封止までの間に、リードフレーム側から該リードフレームを介して粘着テープに放射線照射を行うことが好ましい。
また、本発明の樹脂封止型半導体装置の製造方法によれば、上述した粘着テープを利用することにより、樹脂封止の際の樹脂漏れを効率的に防止することができ、歩留まりの向上を図ることが可能となる。
基材層としては、特に限定されるものではなく、当該分野で使用される粘着テープの基材として用いられる材料からなるものであればどのようなものでも用いることができる。
特に、基材層は、通常の半導体製造プロセスで使用される加熱、特に樹脂封止時の加熱に対して耐性を有するものが適している。例えば、170℃以上、200℃以上、250℃以上、300℃以上の耐熱性を有しているものが挙げられる。封止樹脂は、一般的に175℃前後の温度が付与されることから、このような温度条件下での著しい基材層の収縮又は基材そのものの破壊等が生じないものが好ましい。
ここで、Tgは、ASTM D696に準拠して、熱機械分析装置(例えば、エスアイエステクノロジー社製、TMA/SS600)により求められる値である。つまり、基材層のサンプル(例えば、厚さ1mm×幅4mm)を、荷重19.6mN、室温から10℃/分の速度で昇温させ、熱分析装置にて厚さ方向の熱膨張量を測定し、熱膨張量と温度との関係をグラフ化し、ガラス転移温度と予想される点前後の曲線に接線を引き、これらの接線の交点から求められた値である。従って、300℃以下にガラス転移温度を有さないとは、ガラス転移温度と予想される温度が認識できず、接線の交点がほぼ認められないことを意味する。
基材層は、180℃で3時間加熱した後の熱収縮率が、当該基材層の収縮に伴うリードフレームの反りを防止する観点から、0.40%以下であることが好ましい。
ここで、熱収縮率とは、5cm角の基材層を180℃で3時間加熱したときの、加熱前寸法(5cm)100%に対する、寸法変化の割合(%)を示す。この熱収縮率は、市販の投影機(ミツトヨ製投影機、PJ−H3000F)によって測定することができる。
なお、基材層は、単層でも積層構造でもよい。
ここで、線熱膨張係数は、ASTM D696に準拠して、TMA(サーモ・メカニカル・アナリシス)により測定される値である。
粘着剤層は、耐熱性を有するものであれば、当該分野で通常用いられている粘着剤によって形成することができる。この粘着剤は、感圧型、感熱型、感光型のいずれの型でもよいが、エネルギー線の照射によって硬化するタイプの粘着剤であることが適している。これにより、使用後、被加工物からの剥離を容易に行うことができる。なお、粘着剤層は、基材層の両側に形成されていてもよいが、片側のみに形成されていていることが適している。
架橋剤としては、例えば、イソシアネート系架橋剤、エポキシ系架橋剤、アジリジン系化合物、キレート系架橋剤等が挙げられる。
架橋剤の含有量は特に限定されないが、アクリル系ポリマー100重量部に対して0.1〜15重量部が適しており、0.5〜10重量部が好ましい。架橋剤をこの範囲で用いることにより、粘着剤層の粘弾性を適度に設定することができ、導電性パターン又は封止樹脂に対する粘着剤層の適度な粘着力を確保することができる。よって、粘着テープの剥離時においても、封止樹脂を剥離又は破損したり、粘着剤層の一部が導電性パターン又は封止樹脂に付着することがない。さらに、粘着剤層の過度の硬化を抑制することができる。
粘着剤層は、接着剤成分を調製し、これを基材層に塗布/乾燥することにより形成することができる。接着剤成分の塗布方法としては、バーコーター塗工、エアナイフ塗工、グラビア塗工、グラビアリバース塗工、リバースロール塗工、リップ塗工、ダイ塗工、ディップ塗工、オフセット印刷、フレキソ印刷、スクリーン印刷など種々の方法を採用することができる。また、別途、剥離ライナーに粘着剤層を形成した後、それを基材フィルムに貼り合せる方法等を採用してもよい。
本発明の粘着テープは、基材層と粘着剤層との総膜厚が25〜40μmであることが適しており、25〜35μmであることが好ましい。
このような範囲の総膜厚とすることにより、後述するように、リードフレームに貼着した際にしわの発生を防止することができるとともに、例えば、この粘着テープを貼着したリードフレームを金型に挟持する際のクランプ圧力等との兼ね合いで、効果的に金型の間からの樹脂漏れを防止することが可能となる。
ここで、この粘着力は、測定温度が23±2℃、剥離角度が180°、剥離速度が300mm/分(JIS Z0237に準拠)の条件下に、リードフレームからの剥離によって測定した場合の値である。このような測定は、市販の測定装置(島津製作所製、オートグラフAG-X等)によって行うことができる。
剥離角度120±15°での剥離強度は、1.2N/50mm幅以下、1.0N/50mm幅以下、0.8N/50mm幅以下、0.6N/50mm幅以下、0.3N/50mm幅以下程度であることが適している。
剥離角度150±15°での剥離強度は、1.0N/50mm幅以下、0.8N/50mm幅以下、0.6N/50mm幅以下、0.5N/50mm幅以下、0.3N/50mm幅以下、0.2N/50mm幅以下程度であることが適している。
剥離角度180+0°〜180−15°での剥離強度は、1.0N/50mm幅以下、0.8N/50mm幅以下、0.6N/50mm幅以下、0.5N/50mm幅以下、0.3N/50mm幅以下、0.2N/50mm幅以下程度であることが適している。
本発明の樹脂封止型半導体装置では、粘着テープは、特に、樹脂封止する際に使用される。つまり、リードフレーム表面に搭載された半導体チップを樹脂封止する際にリードフレームの少なくとも一面、例えば、裏面(半導体チップが搭載された面と反対側の面、以下同じ)に貼着され、封止後に剥離するために用いられる。
リードフレームの少なくとも一面、例えば、裏面に本発明の粘着テープを貼り合わせ、
このダイパッド表面に半導体チップを搭載し、
半導体チップ側を封止樹脂により封止し、
封止後に粘着テープを剥離する工程を含む。
さらに、任意に、粘着テープの貼り合わせから剥離の間に、
プラズマ処理を行う工程、
樹脂封止後の封止樹脂の切断工程、
リードフレーム側から該リードフレームを介して粘着テープに放射線照射工程、
ダイパッドに半導体チップを搭載した後の結線工程等を含んでいてもよい。
このような半導体装置の製造方法において、本発明の粘着テープは、主として樹脂漏れを防止するために使用される。なお、粘着テープは、リードフレームにおいて、樹脂で封止される領域以外の表裏面のいずれの領域に貼着されていてもよい。
リードフレーム11は、通常、Cu系素材(Cu−Fe−Pなど)、Fe系素材(Fe−Niなど)等の金属板によって形成されている。また、QFNの端子パターンが刻まれていてもよい。特に、リードフレーム内の電気接点部分(後述する半導体チップとの接続部分)に、銀、ニッケル、パラジウム、金等で被覆(めっき)されているものが好ましい。リードフレーム11の厚みは、通常、100〜300μm程度が挙げられる。
通常、上述したように、リードフレーム11は、半導体チップ15を固定するためダイパッド11cと呼ばれる固定エリアが設けられていることから、半導体チップ15は、ダイパッド11c上に搭載される。
放射線の種類は、特に限定されるものではなく、粘着剤層に含まれる粘着剤の種類によって適宜調整することができる。例えば、紫外線、電子線等が挙げられる。なかでも、紫外線が好ましい。紫外線の波長としては、特に限定されないが、一般的な光重合に用いられる波長を選択することが適しており、例えば、250〜400nmの波長の紫外線が適している。
放射線の照射量は、例えば、粘着剤層に含有されている重合開始剤等の効率を向上させることができる程度であることが適している。具体的には、10〜1000mJ/cm2程度が挙げられ、50〜600mJ/cm2程度が好ましい。粘着剤層の適度な硬化を実現できるからである。
ワイヤボンドは、ボンディングワイヤ16、例えば、金線又はアルミ線などによって行われる。通常、150〜250℃に加熱した状態で、超音波による振動エネルギーと加圧による圧着エネルギーとの併用により行われる。この際、リードフレームに貼着した粘着テープ面を真空引きすることによって、ヒートブロックに確実に固定することができる。
なお、半導体チップ15として、フェイスダウン実装を行う場合には、適宜リフロー工程を行うことができる。
その後、図1(d)に示すように、封止樹脂17を含むリードフレーム11を金型から取り出す。
封止後の粘着テープ20の剥離は、上述したポストモールドキュアの前に行うことが好ましい。
半導体チップ15ごとの分割は、ダイサー等の回転切断刃等を用いて行うことができる。
なお、以下の実施例においては、特に断らない限り、部及び%等は質量基準である。
25μm厚のポリイミドフィルム(東レデュポン、カプトン100H、線熱膨張係数2.7×10−5/K、Tg:402℃)を基材層として用い、この基材層の片面に、シリコーン系粘着剤(東レ・ダウコーニングシリコーン社製、SD4584)100部に対して白金触媒を2.5部加えて塗工/乾燥させて厚さ約6μmの粘着剤層を有する耐熱性粘着テープを作製した(総膜厚:31μm)。
12.5μm厚のポリイミドフィルム(東レデュポン、カプトン50H、線熱膨張係数2.7×10−5/K、Tg:402℃)を基材層として用い、この基材層の片面に、実施例1と同様に、シリコーン系粘着剤を用いて、厚さ約18μmの粘着剤層を有する耐熱性粘着テープを作製した(総膜厚:30.5μm)。
25μm厚のポリエチレンテレフタレートフィルム(東レ製ルミラーS10、熱線膨張係数1.2×10−5/K、Tg:67℃)を基材層として用いた。この基材層の片面に、アクリル酸ブチル−アクリル酸エチル−アクリル酸(アクリル酸ブチル/アクリル酸エチル/アクリル酸=70部/30部/4部)からなるポリマー100部に、イソシアネート系架橋剤(商品名「コロネートL」日本ポリウレタン工業株式会社製)3部、エポキシ系架橋剤(商品名「TETRAD−C」三菱瓦斯化学(株))2部およびトルエンを均一に混合した粘着剤を用いて、厚さ約10μmの粘着剤層を有する耐熱性粘着テープを作製した(総膜厚:35μm)。
粘着剤層の厚みを約35μmとする以外、実施例1と同様に耐熱性粘着テープを作製した(総膜厚:60μm)。
基材層として、12.5μm厚のポリイミドフィルム(東レデュポン、カプトン50H、線熱膨張係数2.7×10−5/K、Tg:402℃)を用い、実施例3と同様のアクリル系粘着剤を、厚さ約6μmとした耐熱性粘着テープを作製した(総膜厚:18.5μm)。
実施例及び比較例で製造した粘着テープを、端子部に銀めっきが施された一辺16PinタイプのQFNが4個×4個に配列された銅製のリードフレームの裏面のアウターパット側に、テープラミネート装置PL−55TRM(日東電工製)を用いて、常温にて密着するように静かに貼り合わせた。なお、このリードフレームのダイパッドには、半導体チップが搭載されており、金線によりワイヤボンディングされたものを用いた。
次いで、エポキシ系封止樹脂(日東電工製HC−300、例えば、樹脂粘度:0.8〜2.0Pa・s)により、モールドマシン(TOWA製Model−Y−serise)を用いて、175℃で、プレヒート40秒、インジェクション時間11.5秒、インジェクション圧力150〜220kN、キュア時間120秒にてモールドした。この際、金型のクランプ圧力を3〜7kN程度とした。
その後、リードフレーム裏面に貼り付けられた粘着テープを剥離した。
さらに、175℃にて3時間程度ポストモールドキュアを行って、樹脂を十分に硬化させた後、ダイサーによって切断して、個々のQFNタイプ半導体装置を得た。このようにしてQFNタイプの半導体装置を製造した後、樹脂漏れを目視にて確認した。
その結果、実施例1〜3では、樹脂漏れは確認されなかった。一方、比較例1では60%以上の端子に樹脂漏れがあることを確認した。また、比較例2では80%以上の端子に樹脂漏れがあることを確認した。
これらの粘着テープの剥離角度90°、120°、150°又は180°でのセパレータ剥離力(単位:N/50mm)を測定した。セパレータ剥離力の評価結果を表1及び表2に示す。
