摘要:
An SiC semiconductor device has a p type region including a low concentration region and a high concentration region filled in a trench formed in a cell region. A p type column is provided by the low concentration region, and a p+ type deep layer is provided by the high concentration region. Thus, since a SJ structure can be made by the p type column and the n type column provided by the n type drift layer, an on-state resistance can be reduced. As a drain potential can be blocked by the p+ type deep layer, at turnoff, an electric field applied to the gate insulation film can be alleviated and thus breakage of the gate insulation film can be restricted. Therefore, the SiC semiconductor device can realize the reduction of the on-state resistance and the restriction of breakage of the gate insulation film.

A method of manufacturing a semiconductor device includes forming a drift layer on a substrate; forming a base layer on the drift layer; forming a trench to penetrate the base layer and to reach the drift layer; rounding off a part of a shoulder corner and a part of a bottom corner of the trench; covering an inner wall of the trench with an organic film; implanting an impurity to a surface portion of the base layer; forming a source region by activating the implanted impurity; and removing the organic film after the source region is formed, in which the substrate, the drift layer, the base layer and the source region are made of silicon carbide, and the implanting and the activating of the impurity are performed under a condition that the trench is covered with the organic film.

A rectangular rear substrate which constitutes an envelope of an image display device is fitted with a reinforcing frame which reinforces the envelope. The reinforcing frame has a pair of first frame portions individually extending substantially parallel to long sides of the rear substrate and a pair of second frame portions extending substantially parallel to short sides of the rear substrate and connecting the first frame portions. Each of the second frame portions meets a relationship ΔH/H=13 to 33%, where H is a length of each long side of the rear substrate and ΔH is a distance between each short side of the rear substrate and each of the second frame portions.
