Abstract

A semiconductor device includes a semiconductor chip provided inside with a p-n junction, an opaque sealing resin covering a surface of the semiconductor chip, and a functional region arranged between the semiconductor chip and the sealing resin and configured to prevent light, which is generated when a forward current flows through the p-n junction and has a particular wavelength causing deterioration of the sealing resin, from reaching the sealing resin.
