Title: Semiconductor device
Inventor: MATSUDA KUNIHIRO
IPC: H01L29/786
Filed: 1990-02-26
Abstract: PURPOSE:To prevent a layer short and to enhance a yield by a method wherein an insulating film is formed of three layers and its intermediate layer is constituted of a material whose kind is different from that of insulating layers sandwiching the intermediate layer. CONSTITUTION:A conductive layer is deposited on a glass substrate 21; a gate electrode 22 is formed. Then, a first-layer insulating film 23 composed of a silicon nitride is deposited; then, an intermediate insulating film 24 composed of alumina or tantalum oxide is deposited on the film 23. Then, a third-layer gate insulating film 25 composed of a silicon nitride is deposited on the film 24. When tantalum oxide is used as the film 24, it is hardly etched by dilute hydrofluoric acid. Since its permittivity is large, the film thickness of the film 24 can be made thick. A high yield can be realized against an etchant which is based on hydrofluoric acid. Even when a very small defect region in the insulating film is etched abnormally, this abnormal etching operation can be stopped by the intermediate layer, and it is possible to prevent a layer short.
