Title
(EN) METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE
(JA) 半導体装置の製造方法
Abstract
(EN)

PROBLEM TO BE SOLVED: To solve the problem of the pressure increasing, which leads to the cause of supplied surplus gas to a gas supply system when an opening and closing valve opens next time, caused by the leakage of a flow rate adjusting valve while the flow rate adjusting valve is closed because the passage system between the flow rate adjusting valve and the opening and closing valve has a certain capacity although the flow rate control of gas in semiconductor manufacturing process is performed by a mass flow controller where a valve with good closing characteristics is inserted in the output side of the flow rate adjusting valve because a small amount of gas flows out when it is closed and the flow rate adjusting valve used here is put the emphasis on adjusting flow rate.

SOLUTION: There is provided the method for manufacturing the semiconductor device which detects the leakage amount of gas flow when closing the flow control valve by measuring the pressure between the flow control valve on the gas discharge side of the mass flow controller and the opening and closing valve.

【課題】半導体製造プロセスにおけるガスの流量制御は、マスフローコントローラによって行われている。ここで使用される流量調整バルブは、流量を調整することに重点が置かれているため、閉鎖時にも微小ながらガスが流出する。このため、流量調整バルブの出力側に閉鎖特性の良好な開閉バルブが挿入されている。しかし、流量調整バルブと開閉バルブ間の流路系には、一定の容量を有するため、流量調整バルブが閉鎖されている間に、この流路系の圧力が流量調整バルブのリークを介して、上昇するという問題がある。このような出力側バルブ間空間の圧力上昇は、次に、開閉バルブが開いたときに、ガス被供給系への余剰のガス供給の原因となる。
【解決手段】本願発明は、マスフローコントローラのガス排出側の流量制御バルブと開閉バルブ間の圧力を計測することで、流量制御バルブの閉鎖時のリークガス流量を検知する半導体装置の製造方法である。
