前記処理室に設けられ、前記基板が載置される載置部と、
前記載置部の上方側に位置して前記処理室の天井部を構成し、前記処理ガスをシャワー状に供給するための複数の第1のガス供給口が形成されるガス供給部と、
前記ガス供給部に上方から対向し、前記処理ガスを横方向に拡散させるための第1の拡散空間を画成する平坦な対向面を備えると共に、前記処理ガスの供給路を形成するガス供給路形成部と、
前記対向面の中央部のまわりに設けられる凹部と、
前記供給路から供給された前記処理ガスを前記第1の拡散空間に横方向に分散させるために周方向に沿って複数のガス吐出口が形成され、前記対向面の中央部のまわりに複数、各々当該対向面から突出せずに前記凹部内に設けられるガス分散部と、
を備えたことを特徴とする。
以下、本発明に関連して行われた評価試験について説明する。
評価試験1
評価試験1−1として図1などで説明した成膜装置1を用いて、図7〜図10で説明したステップS1〜S4に従って成膜処理を行ったときのウエハWの面内における膜厚の分布を調べた。従って、この評価試験1−1で用いた成膜装置1において、ガス分散部44は溝41内に設けられており、対向面34から突出していない。ただし、パージガスは既述のガス貯留タンク72B、72Eを介さず、単位時間あたり比較的少ない流量でガス分散部44に供給されるようにした。また、1サイクルに要する時間は0.38秒に設定した。さらに、評価試験1−2として、パージガスは既述のガス貯留タンク72B、72Eを介して供給され、単位時間あたりにガス供給路形成部3に供給される当該パージガスの流量が、評価試験1−1よりも大きいことを除いては、評価試験1−1と同じ条件で成膜処理を行い、ウエハWの面内における膜厚の分布を調べた。
評価試験2として、上記の評価試験1−2と同様にパージガスを比較的大きな流量で供給することでTiN膜の成膜処理を行い、ウエハWの面内の各部における膜厚を測定した。従って、評価試験2では図1などで説明した、ガス分散部44が対向面34から突出しない成膜装置1を用いている。また、比較試験2として、上記の比較試験1−2と同様にパージガスを比較的大きな流量で供給することでTiN膜の成膜処理を行い、ウエハWの面内の各部における膜厚を測定した。従って、比較試験2ではガス分散部44が対向面34から突出した成膜装置を用いている。また、この比較試験2で用いた成膜装置では、評価試験2で用いた成膜装置1とは図5で説明したガス供給路5の構成が若干異なっており、合流路53の下流側が分岐せずにガス導入用拡散空間55に接続されている。評価試験2、比較試験2共に、1サイクルに要する時間は0.38秒に設定した。
