Abstract: An insulated-gate semiconductor device comprises a source region (S) formed on a predetermined semiconductor substrate such as a spherical semiconductor; a drain region (D) formed on the semiconductor substrate away from the source region; and a gate electrode (G) formed on an insulating layer of the semiconductor substrate to create a channel region between the source and drain regions. The insulated-gate semiconductor device is advantageously used in a rectifier for full-wave rectification of power supplied through inductive coupling of coils. The drain region and the source region are formed asymmetrically with respect to the channel region. In particular, the channel region is formed to surround the source region while the drain region is formed outside the channel region so that the effective channel width viewed from the source region may be different from that viewed from the drain region.
