Process for producing optical semiconductor device

摘要

The present invention relates to a process for producing an optical semiconductor device, the process including: disposing a sheet for optical-semiconductor-element encapsulation including a resin sheet A (1) and a plurality of resin layers B (2) discontinuously embedded in the resin sheet A (1) and a plurality of optical semiconductor elements mounted on a substrate in such a way that each of the plurality of optical semiconductor elements faces either one of the plurality of resin layers B (2); and followed by embedding each of the plurality of optical semiconductor elements in either one of the plurality of resin layers B (2). According to the process of the invention, optical semiconductor elements can be embedded at once. As a result, an optical semiconductor device which is excellent in LED element protection and durability can be easily obtained. Consequently, the optical semiconductor device obtained can have a prolonged life.
