Abstract

Abstract In a CMOS circuit, impurity regions are formed in the channel forming region of each of an n-channel and p-channel transistors along the channel direction. The intervals between the impurity regions in the n-channel transistor is set narrower than those between the impurity regions in the p-channel transistor so as to make the absolute values of the threshold voltages of the n-channel and p-channel transistors approximately equal to each other. Where active layers are formed by utilizing a crystal structural body that is a collection of needle-like or columnar crystals, the same effect can be attained by controlling the width of the needle-like or columnar crystals.
