    Abstract: A trench is formed by performing an anisotropic etching treatment on a silicon substrate with the use of a mask pattern including a pad oxide film, a polysilicon film, and a silicon nitride film formed on the silicon substrate, as a mask. Next, the side surface of the polysilicon film is retreated by etching so that the part of an oxide film formed on the side surface of the polysilicon film may not be hung over the part of an oxide film formed on the side surface of the pad oxide film. Next, an oxide film is formed by performing a thermal oxidation treatment on the inner wall surface of the trench including the exposed side surface of the polysilicon film. This produces a semiconductor device that prevents voids from being formed in a trench isolation structure.

    Abstract: 인덕턴스 L의 성분을 갖는 부하의 역기전력에 기인한 디바이스의 오동작을 억제한다. P형 실리콘 기판 상에 형성된 에피택셜층과, 에피택셜층을 소자형성영역의 N-에피층(4)과 무효영역의 N-에피층(2)으로 분리하는 P+ 확산층(3)과, 무효영역의 N-에피층(2)과 P+ 확산층(3)을 전기적으로 접속하는 알루미늄 배선(6)을 구비한다. 무효영역의 N-에피층(2)과 P+ 확산층(3)을 동전위로 할 수 있기 때문에, 인덕턴스 L의 부하의 역기전력에 의해 소자형성영역에 전자가 주입된 경우라도, P+ 확산층(3)으로부터 무효영역으로의 전자의 공급을 억제할 수 있다.

    Abstract: PURPOSE: To provide a method for manufacturing a semiconductor device by which the separation of a polyimide film from a film which is subjected to isotropic etching is prevented when the polyimide film is turned into imide by a heat treatment and the separation of deposits adhering to the side walls of the films by anisotropic etching is prevented. CONSTITUTION: A silicon nitride film 4 is subjected to isotropic etching by using a polyimide film 5 on which a specified pattern is formed as a mask. Then before anisotropic etching of a silicon oxide film 3, the polyimide film 5 is turned into imide by a heat treatment. At this time, since no deposits produced by dry etching exhibiting anisotropy adhere to the side walls of the films, the polyimide film 5 is never separated from the silicon nitride film 4 when the polyimide film 5 is turned into imide by a heat treatment. Also, deposits are never separated after adhering to the side walls of the films.

The acid supplied by heating is transferred from the inside of the base resist pattern to the inside of the framing material and a crosslinked layer produced at the interface is formed as a layer coating the base resist pattern to thicken the resist pattern and to reduce the hole diameter and separation width of the resist.
