Abstract

트렌치 소지분리와 티타늄 실리사이드 게이트(Ti-Silicide Gate)를 조합하여 상용하는 반도체장치의 제조방법이 포함되어 있다. 본 발명은 티타늄 실리사이드 게이트를 트랜치 소자분리 공정과 조합하여 사용함으로써, 종래 티타늄 실리사이드 게이트를 LOCOS와 조합하여 사용할 때 티타늄 실리사이드가 영향을 받아 게이트라인이 가늘어지는 현상이 없어지고, 따라서 게이트라인의 저항(Resistance) 값이 상승하는 문제점을 해결할 수 있다.A method of manufacturing a commercially available semiconductor device in combination with trench holding separation and a titanium silicide gate is included. According to the present invention, the titanium silicide gate is used in combination with a trench isolation process, so that when the conventional titanium silicide gate is used in combination with LOCOS, the titanium silicide is not affected and the gate line is not tapered. It can solve the problem that resistance value rises.
