ABSTRACT:
A method of fabricating a semiconductor device includes the steps of protecting a front surface of a semiconductor substrate by an adhesive medium, grinding a rear surface of the semiconductor substrate in a state that the front surface is protected by the adhesive medium, removing the adhesive medium from the rear surface, and heating the semiconductor substrate, after the step of removing, to a temperature higher than a thermal decomposition temperature of an adhesive provided on the adhesive medium.
