Abstract
A semiconductor position sensor functions as a PSD or as a two-part split PD or the like, based on control of disconnection/connection of basic, electroconductive strips by controlling a voltage of gate electrode. This semiconductor position sensor does not require a PD separate from the PSD, whereby the device itself can be constructed in compact size. Further, since all signal light can impinge on a photosensitive area, detection sensitivity can be improved.
