Patent number: 8766294Abstract: A semiconductor light-emitting device has a first principal surface, a second principal surface formed on a side opposite to the first principal surface, and a light-emitting layer. A p-electrode on the second principal surface is in the region of the light-emitting layer and surrounds an n-electrode. An insulating layer on the side of the semiconductor layer surrounds the p- and the n-electrodes. A p-metal pillar creates an electrical connection for the p-electrode, and an n-metal pillar creates an electrical connection for the n-electrode. A resin layer surrounds the end portions of the p- and the n-metal pillars, and also covers the side surface of the semiconductor layer, the second principal surface, the p-electrode, the n-electrode, the insulating layer, the p-metal pillar and the n-metal pillar.Type: GrantFiled: December 6, 2012Date of Patent: July 1, 2014Assignee: Kabushiki Kaisha ToshibaInventor: Keisuke Unosawa
