Abstract:
A manufacturing method of a semiconductor device, comprising the steps of:forming a first insulating film above a base in which a first wiring layer is formed, so as to cover the first wiring layer,forming a second insulating film and a third insulating film on the first insulating film, in order,forming a first photoresist pattern on the third insulating film,selectively etching the third insulating film with use of the first photoresist pattern as a mask so as to transfer the first photoresist pattern to the third insulating film, wherein the second insulating film is used as an etching resistance mask for protecting the first insulating film from the etching, andremoving the first photoresist pattern by using the second insulating film as a protection mask for protecting the first insulating film from damage.
