Abstract
본 발명은 절연게이트형 반도체장치, 특히 박막형의 절연게이트형 전계효과 트랜지스터(TFT)의 제작방법에 관한 것으로 종래에 기상성장법에 의해 제작된 절연피막은 계면준위밀도가 높고 핀홀등의 결함이 다수 종재한다는 문제가 있었다. 또한, 최근 게이트 전극으로서, 알루미늄, 티탄, 크롬, 탄탈, 실리콘을 사용하고 그 주위를 양극산화법에 의해 형성한 산화물로 덮음으로써 소스/드레인과 게이트 전극의 겹침을 없애고, 오히려 오프셋 상태로 하여 레이저 아닐에 의해 재결정화시킨 TFT는, 종래의 방법에 의한 TFT에 비해 우수한 특성을 나타냈지만, 그 특성을 재현성 좋게 얻은 것을 곤란하였다. 본 발명에서는 이러한 문제점을 해결하기 위해 게이트 전극의 양극제거할 수 있고, 이와같은 공정을 거침으로서, 게이트 절연막의 신뢰성을 높이고, 제조효율의 향상을 도모할 수 있다. 또한 다량의 TFT에 대해서 양산적으로 전류큐어(cure)를 실시할 수이 있는 절연 게이트형 반도체 장치의 제작방법이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of fabricating an insulated gate semiconductor device, in particular a thin film insulated gate field effect transistor (TFT), in which an insulating film prepared by the vapor phase growth method has a high interfacial density and many defects such as pinholes. There was a problem of ending. In addition, recently, aluminum, titanium, chromium, tantalum, and silicon are used as the gate electrodes, and the surroundings are covered with an oxide formed by anodizing to eliminate the overlap between the source / drain and the gate electrode, but rather to offset the laser. Although TFT which recrystallized by showed the outstanding characteristic compared with TFT by a conventional method, it was difficult to acquire the characteristic with reproducibility well. In the present invention, in order to solve such a problem, the anode of the gate electrode can be removed, and through such a process, the reliability of the gate insulating film can be improved and the manufacturing efficiency can be improved. Moreover, it is the manufacturing method of the insulated-gate semiconductor device which can mass-cure current cure for a large amount of TFT.
