SUBSTRATE FOR OPTICAL SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME, AND OPTICAL SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A substrate for an optical semiconductor device, a manufacturing method thereof, an optical semiconductor device, and a manufacturing method thereof manufacture an optical semiconductor device with high durability and high heat dissipation at low costs by integrally forming a first lead frame and a second lead frame with resin and bonding a resin frame. CONSTITUTION: A light emitting device is mounted on a first lead frame (2). A second lead frame (3) is electrically connected to the light emitting device. The first lead frame and the second lead frame are integrally formed with resin (6). A base part (4) is formed by a transfer mold. A resin frame (5) is bonded on a region where the light emitting device of the base part is mounted. The resin frame is bonded by printing coating or dispenser coating.
