Abstract
The number of mask steps used to fabricate a TFT in an AMLCD is reduced. In particular, source and drain metallizations, as well as doped and undoped semiconductor layers are patterned at the same time, and the source and drain metallizations and the doped semiconductor layer are etched in a single etching step using an insulating passivation layer as a mask to form source and drain electrodes. Manufacturing costs can be reduced and the manufacturing yield can be improved.
