Abstract:
A semiconductor substrate is easily warped by the shrink of the insulating film formed within the deep trench according to the thermal processing in the super junction structure. In order to solve the above problem, in a semiconductor device, an element region and a terminal region are defined on one main surface of the semiconductor substrate. The terminal region is arranged to surround the element region. In the terminal region, a plurality of buried insulators are formed from the main surface of the semiconductor substrate in a way of penetrating an n-type diffusion layer and an n-type column layer and arriving at an n-type epitaxial layer. The buried insulator is formed within a deep trench. The plural buried insulators are arranged in island shapes mutually at a distance from each other.

Claim (Index 8):
The device according to  claim 7 ,\n wherein, of the first buried insulator rectangle portions, the long sides of ones and the short sides of the others are alternately arranged in an intersectional way mutually at a distance from each other.
