Semiconductor device and method for manufacturing the same
First Claim
1. A semiconductor device comprising:
- a substrate;
a light emitting element mounted on the substrate by flip chip bonding;
a sealing structure sealing the light emitting element; and
a phosphor film which is formed on an internal surface of the sealing structure, wherein the sealing structure includes;
a blocking portion which is formed integrally with the substrate so as to surround the light emitting element on the substrate and functions as a reflector that reflects a light emitted from the light emitting element; and
a cover portion which is arranged on top of the blocking portion and is bonded to the blocking portion.

Abstract
There is provided a semiconductor device mounted with a light emitting element, which can be downsized easily, improve light emitting efficiency and be formed easily, and a method for manufacturing the semiconductor device effectively. The semiconductor device includes a substrate, a light emitting element mounted on the substrate by flip chip bonding, a sealing structure sealing the light emitting element and a phosphor film which is formed on an internal surface of the sealing structure. The sealing structure includes a blocking portion which is formed integrally with the substrate so as to surround the light emitting element on the substrate and functions as a reflector that reflects a light emitted from the light emitting element and a cover portion which is arranged on the top of the blocking portion and is bonded to the blocking portion.
