Abstract

PURPOSE: To reduce the cost, by enabling the separation between the elements without using a voltage applying means at the separation region for which the same impurity diffusion as the impurity diffusion for the base of a transistor or a base contact is performed, through the selection of the specific resistance value for the epitaxial layer.
