Abstract
A semiconductor deviceincludes a substrate and an optical sensor unitformed on the substrate for sensing light and for generating a sensing signal, the optical sensor unitincluding a first thin film diodeA for detection of light in a first wavelength range, a second thin film diodeB detecting light in a second wavelength range that contains wavelengths longer than the longest wavelength in the first wavelength range. The first thin film diodeA and the second thin film diodeB are connected in parallel to each other. The sensing signal is generated based on the output from one of the first thin film diodeA and the second thin film diodeB. By this means, the wavelength range that can be detected by the optical sensor unit can be expanded and the sensing sensitivity can be increased.
