Method of manufacturing optical semiconductor device
First Claim
1. A method of manufacturing an optical semiconductor device comprising the steps of:
- forming an optical semiconductor device on a lead frame so that the optical semiconductor device is connected to the lead frame through leads and hanging leads, cutting the leads so that only the hanging leads are connected to the optical semiconductor device to thereby form a support frame in the lead frame, and processing the optical semiconductor device by holding the support frame without unnecessarily touching the optical semiconductor device in a remaining process of manufacturing the optical semiconductor device.

Abstract
An optical semiconductor device includes a semiconductor chip, leads electrically connected to the semiconductor chip, and a package through which the leads are projected. In a manufacturing method, a lead frame is formed to have leads and hanging leads that reach the package of the optical semiconductor device. Then, only the leads are cut from the lead frame to form a support frame where the hanging leads support a plurality of the optical semiconductor devices. During the manufacturing process after the support frame is formed, only the support frame is contacted. Therefore, the optical semiconductor devices are processed in a non-contact state during the manufacturing process.
