Improves light extraction efficiency. A light emitting deviceusing a white resin molding packageintegrally molded with lead framesconstituting an electrode corresponding to one or a plurality of light emitting elementand white resin, wherein an area in a plane view of a white resin surface on a reflective surface that is level with amounting surface of the light emitting elementis configured to be larger than total area in a plane view occupied by surfaces of the lead framesand the light emitting element. Further, a step section is formed on the surfaces of lead frames, white resin is filled in the step section, and the area of white resin surface on a reflective surface where the light emitting elementis mounted is increased.

Light-emitting device with reflective resin

A semiconductor apparatus according to the present invention with a semiconductor element implemented on an insulated substrate comprises: a substrate front surface electrode formed on a front surface side of the insulated substrate and connected with an element electrode of the semiconductor element; a substrate back surface electrode formed on a back surface side of the insulated substrate and electrically connected with the substrate front surface electrode; and a plurality of connection electrodes, extending in a thickness direction of the insulated substrate from one side to the other side of a front surface and a back surface thereof, for electrically connecting the substrate front surface electrode with the substrate back surface electrode, where the substrate front surface electrode or the substrate back surface electrode is formed to have a plane pattern separated for each of the plurality of connection electrodes.

Semiconductor apparatus, inspection method thereof and electric device

There is provided a light emitting device which makes it possible to reduce optical loss and improve brightness by increasing a ratio of fluorescent light that is not reabsorbed by a light emitting element while decreasing a ratio of scattered light that is reabsorbed by the light emitting element. Individual faces forming outer faces of the light emitting elementare in contact with a bonding memberor sealing member. The bonding memberand the sealing membercontain a fluorophor. Emitted light emitted from the faces of the light emitting elementis transformed into fluorescent light by the fluorophor. Therefore, the ratio of scattered light that is not transformed from the emitted light into the fluorescent light can be decreased while the ratio of fluorescent light is increased.
