SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD OF THE SAME |
摘要 |
At least part of a semiconductor layer or a semiconductor substrate includes a semiconductor region having a large energy gap. The semiconductor region having a large energy gap is preferably formed from silicon carbide and is provided in a position at least overlapping with a gate electrode provided with an insulating layer between the semiconductor region and the gate electrode. By making a structure in which the semiconductor region is included in a channel formation region, a dielectric breakdown voltage is improved.
