SEMICONDUCTOR LIGHT EMITTING DEVICE AND METHOD FOR MANUFACTURING SAME

摘要

According to one embodiment, a semiconductor light emitting device includes a light emitting chip and a fluorescent material layer. The light emitting chip includes a semiconductor layer, a first electrode, a second electrode, an insulating layer, a first interconnect layer, a second interconnect layer, a first metal pillar, a second metal pillar, and a resin layer. The semiconductor layer includes a light emitting layer, a first major surface, and a second major surface formed on a side opposite to the first major surface. The fluorescent material layer is provided on the first major surface and has a larger planer size than the light emitting chip.
