Title: Semiconductor device and manufacture thereof
Inventor: YASUNAGA TOMOKO
IPC: H01L29/78
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To enable a leakage current to flow less between a gate electrode and a source or a drain by a method wherein a flat is provided in the upside of a side wall provided to the gate electrode formed on a semiconductor substrate through the intermediary of a gate insulating film. SOLUTION: A structure composed of a gate electrode 104, a silicon nitride film 105, and a silicon oxide film 106 is subjected to anisotropic dry etching etching gas to make the gate electrode 104 exposed. Furthermore, an Si substrate is subjected to over-etching. At this point, the silicon nitride film 105 is higher in etching rate than the silicon oxide film 106, so that the silicon oxide film 106 is hardly etched, and only the silicon nitride film 105 is etched. Moreover, ions slightly inclined in a vertical direction are present even in anisotropic etching, the silicon nitride film 105 is also etched by the slightly inclined ions and more etched than the silicon oxide film 106. By this setup, the silicon nitride film 105 becomes flat.
