  • Method for manufacturing optical bench, optical bench, optical module, silicon wafer substrate in which wiring and groove are formed, and wafer
    Patent number: 7118933
    Abstract: An optical bench on which an optical component is mounted comprises an Si substrate made of a silicon wafer, a groove disposed on the Si substrate and designed to mount the optical component thereon, and a metal thin-film wiring for driving the optical component or a driver component. The metal thin-film wiring is formed in an electroless plating process before a groove manufacturing process which forms the groove by micromachining by means of wet processing.
