  • Optical cap for semiconductor device
    Patent number: 6984849
    Abstract: An optical cap for semiconductor device, the cap comprising: a metal cap body having an opening and a transparent optical window sealed with the metal cap body to cover the opening by means of a sealing member. The sealing member includes a bismuth low-melting point glass containing no lead, an intermediate metal layer attached to the metal cap body, the intermediate metal layer being a metal capable of causing a eutectic reaction with respect to Bi contained in the low-melting point glass, and an eutectic alloy layer thus formed between the low-melting point glass and the intermediate metal layer.
    Type: Grant
    Filed: April 1, 2004
    Date of Patent: January 10, 2006
    Assignee: Shinko Electric Industries Co., LTD
    Inventors: Hironori Nishizawa, Yasushi Hatakeyama, Toshihisa Yoda, Kenji Kawamura
