Patent ID: 8602661

Claim:
A manufacturing method of a housing-integrated optical semiconductor component, comprising the steps of: packaging a plurality of optical devices on a lead frame having a leg portion; forming an optical semiconductor component by sealing a periphery of the optical devices by an optically transmissive material; forming a first through hole in the optical semiconductor component, the first through hole being disposed between the optical devices; and thereafter integrally molding a housing to the optical semiconductor component so that the housing has a second hole through which lights from/to the optical device pass, and covers the sealed portion of the optical semiconductor component formed in the sealing step, wherein: the optically transmissive material includes silicone, a material of the housing includes a liquid crystal polymer, and the optically transmissive material is softer than the housing; and the material of the housing is filled into the first through hole in the optical semiconductor component in the integrally molding step.
