Patent ID: 6995045

Claim:
A method of forming a thin film transistor (TFT), comprising: providing a substrate; forming a gate and a non-transparent structure on said substrate; forming a dielectric layer which covers said gate on said substrate; forming a first semi-conductive layer on said dielectric layer; forming a second semi-conductive layer on said first semi-conductive layer; forming a photoresist layer on said second semi-conductive layer; placing a mask on said photoresist layer, wherein said mask has a slit pattern aimed at said gate; patterning said photoresist layer to form a photoresist pattern over said gate and still over said substrate around said gate, wherein said photoresist pattern further comprises a thin photoresist pattern formed under said slit pattern and a thick photoresist pattern; removing the portions of said second semi-conductive layer and said first semi-conductive layer without said photoresist pattern covering; removing said thin photoresist pattern; and removing the portion of said second semi-conductive layer without the portion of the photoresist pattern covering.
