Abstract:
A semiconductor device having a first surface formed at a first height and a second surface formed at a second height on a semiconductor substrate includes: a base region formed in the semiconductor substrate; a trench formed from the first surface and the second surface into the semiconductor substrate; a gate insulating film covering an inner side of the trench; a gate electrode embedded to a third height; an insulating film formed on the gate electrode; a first region which has the first surface and in which a base contact region is formed; and a second region which has the second surface and in which a source region is formed, the first region and the second region being alternately arranged in the trench extension direction to prevent a reduction in channel formation density.

Claim (Index 6):
A semiconductor device according to  claim 3 , wherein the semiconductor device is an insulated gate bipolar transistor including a collector layer of the second conductivity type between the back surface semiconductor electrode layer and the second electrode.
