Abstract: 소정부분의 식각시 그 식각되는 부분과 식각선택비가 비슷한 재질이 그 하부에 있을경우 과잉식각에 의한 손상을 방지할 수 있도록 한 박막트랜지스터의 제조방법에 관한 것으로, 기판상에 소정길이의 게이트를 형성하고 전면에 소정두께의 절연막, 최종형성 두께보다 두꺼운 비정질 실리콘을 차례로 증착시키는 제1공정과, 상기 비정질실리콘을 소오스 및 드레인전극 형성영역으로 한정해서 그 부분에 대해서 일정두께가 되도록 식각하는 제2공정과, 전면에 소정도전형의 비정질 실리콘을 도포하는 제3공정과, 상기 소정도전형의 비정질 실리콘과 상기 비정질실리콘을 트랜지스터 형성영역만 남기고 제거하는 제4공정과, 그위에 소오스 및 드레인 전극을 형성한후 상기 전극 형성시 노출된 소정도전형의 비정질실리콘을 식각하고 그 하부의 비정질실리콘의 일정두께가 되도록 더 식각하는 제5공정으로 이루어진다.

Title: Polymeric film
Inventor: MILLS PAUL DAVID ALAN
IPC: B32B27/20
Filed: 1992-05-15
Granted: 1999-06-15
Abstract: A polymeric film, particularly a polyester film, comprising an essentially unfilled primary layer substrate and a filled secondary layer exhibiting an improved combination of transparency and handling properties. The filler is glass particles having a volume distributed median particle diameter of 1.0 to 7.0  mu m, which are present in the secondary layer at a concentration of 100 to 1000 ppm. The film is suitable for use in a wide range of applications, particularly for information storage and display.
