Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a method of designing a MOS transistor, which can raise the accuracy of the design of the transistor in consideration of the effect of reduction of impurity concentration within a channel. SOLUTION: The initial value of an impurity concentration NA within a channel is set (step 10). Subsequently, the effect of reduction of the impurity concentration within the channel due to a channel length is evaluated using an analytic model formula and the ratio (r) of a residual impurity concentration within the channel in the proposed gate length to the impurity concentration within the channel on the side of a long channel is found (step 102). Subsequently, for reinforcing the component of reduction of the impurity concentration within the channel, the initial value of the concentration NA within the channel is divided by the above ratio (r) and the value obtained by the division is decided as the design value of the last impurity concentration within the channel (step) 103.  That is, the impurity concentration in the purposed gate length becomes impurity concentration of rNA to the impurity concentration NA on the side of the long channel.
