Patent ID: 8085825

Claim:
A semiconductor laser diode apparatus comprising: a substrate; a first semiconductor laser diode portion having a cavity, formed on a surface of said substrate; and an electrode layer electrically connected to a first surface of said first semiconductor laser diode portion, wherein said cavity extends in a first direction, said first direction is parallel to said surface of said substrate, a second surface of said first semiconductor laser diode portion is opposite to said first surface, and said second surface is bonded to said substrate through a conductive adhesive layer, a length in a second direction of said substrate is larger than a length in said second direction of said first semiconductor laser diode portion, said second direction is parallel to said surface of said substrate, said second direction intersects with said first direction, said electrode layer is formed on both said first surface and an adjacent surface of said substrate to said first semiconductor laser diode portion in said second direction, said electrode layer extends in said second direction from said first surface to said adjacent surface of said substrate, an insulating film is formed between said electrode layer and said conductive adhesive layer, a metal wire is wire-bonded onto said electrode laver, and a wire-bonded portion of said metal wire is positioned over said adjacent surface of said substrate.
