Filed: 1984-07-06
Abstract: PURPOSE:To restrain resist from deterioration and undercut by a method wherein an insulating film containing no oxygen is formed on another insulating film mainly comprising SiO2 and a conductive film deposited on the former insulating film is plasma-etched. CONSTITUTION:An SiO2 film 17 is formed on a semiconductor substrate 11 to deposit an Si3N4 film 18 on the film 17. Next a contact hole 19 passing through a source region 15 and a drain region 16 is opened by etching the films 18 and 17. Firstly after depositing an Al film 20 on overall surface, a resist pattern 21 is formed on the film 20. Secondly the film 20 is plasma-etched utilizing the pattern 21 as a mask. Thus the film 20 is patterned to be removed at the opening of pattern 21. Resultantly a wiring 21' connecting to the regions 15, 16 through the intermediary of the hole 19 is patterned. Through these procedures, the film 17 may be prevented from producing oxygen atoms while restraining the resist 21 from deterioration and undercut in case of plasma etching process by means of forming the film 18.
