Patent ID: 8492767

Claim:
A manufacturing method of a thin film transistor (TFT) substrate, comprising: after a first metallic layer is formed on the TFT substrate, annealing the TFT substrate so that lattices of the first metallic layer are re-arranged to prevent occurrences of lattice interface defects in the first metallic layer; wherein annealing the TFT substrate comprises: placing the TFT substrate in a temperature-rising environment and controlling a temperature of the temperature-rising environment to rise from 25° C. to 400° C.˜600° C. at a uniform rate within 30˜60 minutes; keeping the temperature of 400° C.˜600° C. for 40˜60 minutes; and controlling the temperature of the temperature-rising environment to decrease to 25° C. at a uniform rate within 60˜80 minutes.
