Optical semiconductor device and method for manufacturing same

摘要

According to one embodiment, an optical semiconductor device includes a light emitting layer, a transparent layer, a first metal post, a second metal post and a sealing layer. The light emitting layer includes a first and a second major surface, a first and a second electrode. The second major surface is a surface opposite to the first major surface, and the first electrode and second electrodes are formed on the second major surface. The transparent layer is provided on the first major surface. The first metal post is provided on the first electrode. The second metal post is provided on the second electrode. The sealing layer is provided on the second major surface. The sealing layer covers a side surface of the light emitting layer and seals the first and second metal posts while leaving end portions of the first and second metal posts exposed.

1. An optical semiconductor device, comprising:
a light emitting layer having a first major surface and a second major surface opposite to the first major surface; a first electrode provided on the second major surface; a second electrode provided on the second major surface; a transparent layer provided on the first major surface, the transparent layer being transparent, and the transparent layer laterally extending beyond the light emitting layer;a fluorescent layer provided on the transparent layer and containing phosphor,
a first metal post provided on the first electrode; a second metal post provided on the second electrode; and a sealing layer provided on the second major surface, the sealing layer being formed of a material that is light-shielding with respect to a light emitted from the light emitting layer, the sealing layer sealing the first metal post and the second metal post, and the sealing layer covering a side surface of the light emitting layer, a side surface of the transparent layer having a portion that is not covered with the fluorescent layer and the sealing layer, a part of the light emitted from the light emitting layer propagating through the transparent layer and entering the fluorescent layer, and another part of the light emitted from the light emitting layer propagating through the transparent layer and emitted outside from the side surface of the transparent layer.
