ABSTRACT:
A method of fabricating integral-type LCD devices incorporating polysilicon-type TFTs reduces the number of masks required to fabricate a thin film transistor (TFT). According to the method, a lightly-doped-drain (LDD) type TFT is formed using a single photoresist pattern and a photoresist ashing technique.
