Abstract:
1. A semiconductor element comprising a plurality of field effect transistors each including: a schottky electrode which is disposed on the upper surface of said drift region so as to form a schottky junction with the upper surface of said drift region, wherein: said semiconductor layer is divided into a plurality of cells by a virtual border line in plan view; said drift region and said second source/drain electrode are formed so as to extend over the plurality of cells; the plurality of cells are constituted of a transistor cell in which said field effect transistor is formed and a diode cell in which said schottky electrode is formed; the plurality of transistor cells are formed adjacent to each other in a transistor forming region; and a diode forming region where the diode cells, the number of which is one or more, are formed is formed so as to surround the transistor forming region.
