Abstract

PURPOSE: To increase the dielectric strength as well as to decrease the output conductance with a high speed and a high density by setting the impurity concentration right under the channel formation region lower than the concentration on the channel surface and inside the substrate when forming the N-type channel to the P-type semiconductor substrate.
