Title: Etching method of organic film
Inventor: MIZUSHIMA KAZUYOSHI
IPC: H01L21/28
Filed: 2001-06-25
Abstract: PROBLEM TO BE SOLVED: To solve the problem that conventionally reduction in the throughput of an organic film etching apparatus is caused by the requirement of long time for allowing a covering to be subjected to etching removal in a second step by the mixed gas of N2 and H2 , since the covering that is the decomposed object of SO2 and uses S as a main constituent is generated in a first step for etching the organic film by the mixed gas of SO2 and N2 . SOLUTION: In second steps (T3 to T4 ) for removing a covering by etching, the covering is removed by the plasma of the mixed gas of N2 and H2 , thus allowing the H2 to react to S in the covering for generating volatile H2 S, reducing the time required for removal (T3 to T4 ) of the covering, and hence improving reduction in the throughput of an organic film etching apparatus.
