Abstract

Official abstract text for this publication.

A source region of a MOSFET includes: a source contact region connected to a source pad; a source extension region adjacent to a channel region in a well region; and a source resistance control region arranged between the source extension region and the source contact region. The source resistance control region is different in an impurity concentration from the source extension region and the source contact region. These three regions are connected in series between the source pad and the channel region in the well region.
