  • Patent number: 8749263
    Abstract: 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.

  • Publication number: 20100022040
    Abstract: [Object] To restrain color variation in light emitted from a light-emitting device. [Means to achieve the object] A method for producing a light-emitting device includes the steps of: (a) die-bonding a chip onto a substrate so as to prepare a die-bonded substrate; (b) preparing a mold having a cavity; (c) setting the die-bonded substrate such that the chip is placed in the cavity; and (d) injecting sealing resin into the cavity via a runner section. In the method, the runner section is capable of maintaining its temperature at a low temperature lower than a temperature of the mold and the step (d) injecting the sealing resin that is maintained at the low temperature in the runner section, into the cavity via the runner section.
