摘要:
An insulated gate field effect transistor formed on one main surface of a semiconductor substrate comprises a drain region the impurity concentration of which is lower than twice that of the semiconductor substrate and the conductivity type is reverse to that of the substrate and a region of a high impurity concentration, formed in the low impurity concentration region, the conductivity type of which is the same as that of the low impurity concentration region.
