Patent ID: 7816258

Claim:
A method for manufacturing an electro-optic device substrate, comprising: forming a TFT element having a source region and a drain region on a base, the TFT element including a silicon layer in the source region or the drain region; forming an insulating layer on the silicon layer; forming a contact hole in the insulating layer; forming a titanium layer so as to be in contact with the silicon layer at the contact hole in an atmosphere; forming a titanium nitride layer on the titanium layer in equipment that is the same as equipment used for the forming the titanium layer; and annealing the base having the layers up to the titanium nitride layer to silicide the portion of the silicon layer in contact with the titanium layer, thereby forming a titanium silicide layer, the titanium silicide layer being formed between the silicon layer and the titanium layer, and the annealing being performed after the forming of the titanium nitride layer on the titanium layer.
