  • Optical wiring layer, optoelectric wiring substrate, mounted substrate, and methods for manufacturing the same
    Patent number: 6438281
    Abstract: A first clad layer is formed on a smooth support substrate via a release layer. On the first clad layer, a core through which light propagates and alignment marks are simultaneously formed. Further, these layers are covered with a second clad to obtain an optical wiring layer. Then, the optical wiring layer is released from the support substrate and stuck to a substrate having an electric wiring. Subsequently, on the resulting substrate are formed a mirror for reflecting light propagating through the core, pads for installing optical parts or the like, and via holes for electrically connecting the electric wiring on the substrate to the pads. For this formation, the alignment marks are used as references.
