Abstract:
A semiconductor device with a simplified structure including an energization control element and reverse coupling protection element, and a manufacturing method therefor. Its semiconductor substrate has deep and shallow trenches in its first surface. A first n-type impurity region lies in its second surface in contact with the deep trench bottom. A p-type impurity region includes: a p-type base region to make a pn junction with the first n-type region and in contact with the shallow trench bottom; and a back gate region joined to the p-type base region, lying in the first surface. A second n-type impurity region makes a pn junction with the p-type impurity region, lying in the first surface in contact with the shallow trench side face. An n +  source region makes a pn junction with the p-type region, lying in the first surface in contact with the side faces of deep and shallow trenches.

Claim (Index 6):
The semiconductor device according to  claim 1 ,\n wherein the deep trench has a first deep trench part and a second deep trench part, wherein the shallow trench has a first shallow trench part and a second shallow trench part, wherein the first deep trench part surrounds the first shallow trench part in the first surface and the second deep trench part surrounds the second shallow trench part in the first surface, and wherein the first deep trench part and the second deep trench part are separated from each other.
