続いて本技術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として、図1で説明した成膜装置1を用いて既述の成膜処理時と同様にバルブV1を繰り返し開閉すると共に、処理容器11に処理ガスを供給した。その間にMFM56から出力される検出信号を取得して、検出される流量をモニターした。つまり、処理ガス供給管52にオリフィス55を設けた状態で流量の検出を行った。また、比較試験1として、処理ガス供給管52にオリフィス55が設けられないことを除いては、評価試験1と同様の条件で流量の検出を行った。
評価試験2として、評価試験1と同様に処理ガス供給管52にオリフィス55が設けられた状態で、バルブV1を繰り返し開閉すると共に、処理容器11に処理ガスを供給した。互いに同じ条件でこの処理ガスの供給を5回行い、各回における原料ガスの流量の算出値の推移を調べた。また、比較試験2として、処理ガス供給管52にオリフィス55が設けられないことを除いては、評価試験2と同様の試験を行った。
