Abstract
A semiconductor switch device and a method of manufacturing the semiconductor switch device are provided. The semiconductor switch device includes semiconductor elements on a single semiconductor substrate. At least one of the semiconductor elements constitutes a switch circuit and at least one other of the semiconductor elements constitutes a logic (connection) circuit. Each semiconductor element includes a recess, a gate electrode in the recess, a drain electrode, and a source electrode. In one representative aspect, the gate electrode in the switch circuit can have a rectangular external shape in section, and the gate electrode in the connection circuit has a shape in section other than rectangular.
