Patent ID: 7146106

Claim:
An optic semiconductor module comprising: a main board of an approximately planar plate shape having an aperture therethrough and a plurality of board metal patterns formed at a periphery of the aperture; a package portion coupled to the main board, the package portion comprising: a laser diode for converting an electric signal to an optical signal; a photo detector for converting an optical signal to an electric signal, wherein the laser diode and the photo detector are electrically coupled to the main board through the board metal patterns; a cap type substrate comprising: a base having inside surfaces defining a space within the base and defining an opening at a lower part of the base; a plurality of substrate metal patterns formed on first portions of the inside surfaces and an outside surface of the base; and an adhesive layer interposed between the substrate metal patterns and the first portions of the inside surfaces and the outside surface of the base, wherein the laser diode and the photo detector are bonded to a second portion of the inside surfaces of the base; a plurality of conductive wires electrically connecting the laser diode and photo detector to the substrate metal patterns; a glass attached to a perimeter edge of the opening; and a glass attach material interposed between the glass and the perimeter edge of the opening, wherein the glass and the glass attach material seal the opening; and an optical fiber inserted into the aperture of the main board, an end of the optical fiber being disposed adjacent to the package portion.
