Abstract
A semiconductor switch includes an insulating film on a semiconductor substrate. A switching circuit is on a first portion of the insulating film. The switching circuit is configured to switch a path of a high-frequency signal. A wiring layer is provided on the insulating film. The wiring layering includes a signal wire and a ground wire. A conductive layer is between the wiring layer and the insulating film. The conductive layer, in some embodiments, includes a first conductive region between the high-frequency wiring and the insulating film and a second conductive region between the grounding wiring and the insulating film.
