  • Method for producing a monolithically integrated optoelectronic device
    Patent number: 5001080
    Abstract: A semiconductor device including a substrate having a low substrate surface formed in the substrate with a first gentle slope from the substrate surface; a single crystalline layer formed on the low substrate surface nearly level with the substrate surface and having a gentle slope facing the first gentle slope; an optical semiconductor element is constructed using the single crystalline layer. An electronic semiconductor element is constructed using the substrate surface. A wiring layer connects electrodes of the optical semiconductor element and the electronic semiconductor element through the first and the second gentle slopes.
    Type: Grant
    Filed: October 26, 1987
    Date of Patent: March 19, 1991
    Assignee: Fujitsu Limited of 1015
    Inventors: Osamu Wada, Tatsuyuki Sanada, Shuichi Miura, Hideki Machida, Shigenobu Yamakoshi, Teruo Sakurai
