Abstract
Description
CN204151456は、半導体のエピタキシャルウェハを作製するためのMOCVD反応装置を開示している。
反応チャンバ内の加熱されたサセプタの上に、基板を与えるステップを含み、上記チャンバは冷却された複数の入口を有し、当該複数の入口は、使用時に上記基板全体にわたって分散しかつ上記基板からの離隔距離が一定になるように配置されており、
上記加熱されたサセプタを、少なくとも300rpm、好ましくは600〜3000rpmの回転数で回転させるステップと、
上記入口を通して上記反応チャンバ内に前駆体化合物を含む流れを供給し、それにより、上記前駆体化合物を分解して上記基板上にグラフェンを形成するステップとを含み、
上記入口は、100℃未満、好ましくは50〜60℃に冷却され、上記サセプタは、上記前駆体の分解温度を上回る、少なくとも50℃の温度まで加熱され、
上記一定の離隔距離は、少なくとも12cm、好ましくは12〜20cmである。
本発明は、異なる設計のMOCVD反応器の使用を含む。その一例として、本明細書に記載のグラフェン成長にとって効率が良いことが実証されているものが意図されている。この設計は、いわゆる高回転数(High Rotation Rate)(HRR)または「渦」流システムである。WO2017/029470に記載の密結合反応器は非常に高い熱勾配を用いてグラフェンを作製することを重視するが、上記新たな反応器は注入ポイントと成長面または基板との間隔が非常に広い。密結合は、元素状態の炭素を、場合によってはその他のドーピング元素を基板表面に与えてグラフェン層が形成されるようにする前駆体を極めて急速に解離させることができる。一方、新たな設計は前駆体の渦に依拠する。
次に、本発明を、非限定的な以下の図面を参照しながらさらに説明する。
反応器の壁は、壁1Aの内側表面1Bを含む反応器の壁の内側表面に対して実質的に隣接して(典型的には数ミリメートルの距離で)延在する1つ以上の内部チャネルおよび/またはプレナム(plenum)8を画定する。動作中、水をポンプ9によりチャネル/プレナム8を通してポンピングすることにより、壁1Aの内側表面1Bを200℃以下に保つ。一部には入口3の直径が比較的狭いことから、(典型的には内側表面1Bの温度よりも遥かに低い温度で保存される)前駆体の温度は、壁1Aの入口3を通ってチャンバ1に入るときに、実質的に壁1Aの内側表面1Bの温度以下になる。
次に、本発明を、非限定的な以下の例を参照しながらさらに説明する。
上記詳細な説明は、説明および例示のために提供され、添付の請求項の範囲を限定することを意図している訳ではない。本明細書に例示されている現在好ましい実施形態の多数の変形は、当業者には明らかであろう変形であり、なおも添付の請求項およびその均等物の範囲に含まれる。
