Abstract

PURPOSE: To improve the dielectric strength of a junction by the constitution in which a reversely-conductive region to a semi-conductor substrate as the source region or drain region of a MOS transistor is made several μm or more away from the guard ring layer of the same conductive direction as and higher in impurity density than the substrate and the region is not provided under the gate electrode.
