  • Publication number: 20140319567
    Abstract: A provided light includes a semiconductor chip including a p-type semiconductor layer and an n-type semiconductor layer, the semiconductor chip being adapted to emit light between the p-type semiconductor layer and the n-type semiconductor layer; a p-side pad electrode disposed on an upper surface side of the semiconductor chip and over the p-type semiconductor layer; an n-side pad electrode disposed on an upper surface side of the semiconductor chip and over the n-type semiconductor layer; a resin layer disposed to cover the upper surface of the semiconductor chip; a p-side connection electrode and an n-side connection electrode disposed at an outer surface of the resin layer and positioned on the upper surface side of the semiconductor chip; and a metal wire disposed in the resin. The metal wire is adapted to make connection at least one of between the p-side pad electrode and the p-side connection electrode, and between the n-side pad electrode and the n-side connection electrode.

  • Publication number: 20140227813
    Abstract: A light emitting element for flip-chip mounting having a flat mounting surface which allows a decrease in the width of the streets of a wafer. In the light emitting element, the insulating member filling around the bumps and flattening the upper surface is formed with a margin of a region with a width which is equal to or larger than the width of the streets on the dividing lines, so that at the time of dividing the wafer along the dividing lines, the insulating member is not processed, which allows designing of the streets with a small width.

  • Publication number: 20140027804
    Abstract: To provide a method of manufacturing at low cost a light emitting device that converts the wavelength of light radiated by a light emitting element and emits, the method includes: forming a phosphor layer on a translucent substrate; arranging a plurality of light emitting elements with a predetermined spacing, the light emitting elements having an electrode formed face provided with positive and negative electrodes respectively and arranged with the electrode formed faces on the top; embedding a resin containing phosphor particles so that an upper face of the embedded resin does not bulge over a plane containing the electrode formed faces; and curing the resin, and then cutting and dividing the cured resin, the phosphor layer and the translucent substrate into a plurality of light emitting devices each including one or more of the light emitting elements.
