Description
[0001]本発明は、半導体集積回路製造の分野に係り、より詳細には、シリコン酸化物膜の中間温度堆積及び高温度堆積、並びにこれら酸化物膜の製造方法に係る。
[0002]化学蒸気堆積(CVD)されたSiO2膜、並びにそれらの二元及び三元シリケート(一般に酸化物膜と称される)は、マイクロプロセッサやメモリのような集積回路の製造に広く利用されている。これらの膜は、ポリシリコンと金属層との間の絶縁材、多レベル金属系統における金属層間の絶縁材、拡散ソース、拡散及びインプランテーションのマスク、スペーサ、及び最終不活性化層として使用される。受け入れられる堆積酸化物膜プロセスは、厚み及び組成が均一で、粒子及び化学的汚染が少なく、基板への付着が良好で、且つ製造スループットが高いものである。
