Abstract:
A lateral IGBT comprising:a semiconductor substrate;an insulating film formed on said semiconductor substrate;a first base region of a first conductivity type formed on said insulating film;a second base region of a second conductivity type, which is formed in a surface region of said first base region;a first gate insulating film formed on an inner wall of a first LOCOS groove formed passing through said second base region to reach said first base region;a first gate electrode formed on said first gate insulating film;first source region of a first conductivity type, which is formed in a surface region of said second base region around said first LOCOS groove in such a manner as to contact with said first gate insulating film;a first drain region of a second conductivity type, which is formed in a surface region of said first base region in such a manner as to be spaced apart from said second base region;a source electrode formed on said first source region and on said second base region; anda drain electrode formed on said first drain region.
