Description
[例1]
本例では、グラファイトキャリアが、キャリアの中心付近から縁付近まで延伸する少なくとも3本の放射状の溝を含む。放射状の溝は、好ましくは対称に配置されて、キャリアの半径方向に沿った剛性を与え、キャリアを凸状や凹状にしてしまう撓みを軽減する。このキャリアの撓みの変動の軽減は、一貫したポケットの床部の形状をもたらして、目的通りのウェーハからキャリアまでの間隔を与えて、ウェーハ内部の均一性、つまりは歩留まりを向上させる。
本例では、グラファイトキャリアが、少なくとも一つの円形の溝、好ましくはキャリアに対して同心円状の三つの円形の溝を含む。この円形の特徴は、外周付近のキャリアの剛性を増大させて、キャリアを湾曲させたり歪ませたりしてしまう撓みを軽減する機能を果たす。これは、均一に平坦なキャリア縁を与え、以下の二つの主な役割を果たす。即ち、ポケットの床部の形状が、キャリア形状に変動がないことに起因して一貫性のあるものとなる。また、キャリアと反応器の構成要素との間の間隔が一貫性のあるものとなる。反応器の構成要素としては、熱源、ガス供給システムや、間隔がその動作にとって重要となる計測機器が挙げられる。キャリアとこれら構成要素との間の間隔の一貫性は、均一な堆積パラメータ又は成長パラメータ(温度、濃度、圧力、流量等)を与える。更に、同心円状の溝は、キャリアのポケットが平坦であって凸状ではなく、基板が均等に加熱及びコーティングされることを保証する。
本例では、グラファイトキャリアが、少なくとも1本の円形の溝と、少なくとも3本の放射状の溝とを含む。放射状の溝は、キャリア構造体の半径方向に沿った剛性を与え、基板キャリア構造体を凸状や凹状にしてしまう撓みを軽減する。これと同時に、円形の溝が外周付近のキャリアの剛性を増大させて、キャリアを湾曲させたり歪ませたりしてしまう撓みを軽減する機能を果たす。結果として、ポケットの床部の形状が、基板キャリア構造体の形状に変動がないことに起因して一貫性のあるものとなる。この基板キャリア構造値の撓みの変動の減少は、一貫性のあるポケットの床部の形状をもたらす。これは、ウェーハ基板上に均一に堆積/成長した層を更にもたらすが、その理由は、基板キャリア構造体と基板ウェーハとの間の間隔が最適化されて、温度分布が改善されるからである。これは、成長プロセスにおける基板キャリア構造体の使用中に、コーティングされる基板が均等に加熱及びコーティングされて、コーティングされた製品の高い品質をもたらすという更なる利点を有する。また、キャリアと反応器の構成要素との間の間隔が一貫性のあるものとなる。反応器の構成要素としては、熱源、ガス供給システムや、間隔がその動作にとって重要となる計測機器が挙げられる。キャリアとこれら構成要素との間の間隔の一貫性は、均一な堆積パラメータ又は成長パラメータ(温度、濃度、圧力、流量等)を与える。
