Abstract
A method of manufacturing a semiconductor device, which has a gate electrode and a pair of diffusion layers formed in a semiconductor substrate on sides of the gate electrode, includes forming an insulating film and a gate electrode on a semiconductor substrate, obtaining a thickness of an affected layer formed in a surface of the semiconductor substrate, forming a pair of diffusion layers by injecting an impurity element into the semiconductor substrate in areas flanking the gate electrodes based on a predetermined injection parameter, performing activating heat treatment based on a predetermined heat treatment parameter, and a parameter deriving step provided between the obtaining step and the diffusion layer forming step, the parameter deriving step deriving the injection parameter or heat treatment parameter in response to the obtained thickness of the affected layer such that the diffusion layers are set to a predetermined sheet resistance.
