Abstract
A semiconductor device includes a photodiode formed using a silicon substrate, a wide-bandgap semiconductor layer formed on the silicon substrate and having a bandgap larger than that of silicon, and a switching element formed using the wide-bandgap semiconductor layer. The switching element is electrically connected to the photodiode so as to be on/off-controlled by a control signal from the photodiode.
