Abstract:
A method of calculating characteristics of a semiconductor device, comprising the steps of:determining a gate length of a semiconductor device including a gate electrode on or above a partial area of a surface of a semiconductor substrate and setting the gate length determined as an upper-limit gate length; determining an impurity implantation condition for a semiconductor device of which a gate length is substantially equal to said upper-limit gate length and calculating a representative impurity concentration distribution of the semiconductor device; obtaining a limit gate length according to said representative impurity concentration distribution; determining, for a semiconductor device of which a gate length is equal to or greater than said limit gate length and equal to or less than said upper-limit gate length, an impurity concentration distribution of the semiconductor device according to said representative impurity concentration distribution; and obtaining characteristics of the semiconductor device according to the impurity concentration distribution thus determined.
