  • Semiconductor photodetectors
    Patent number: 8257997
    Abstract: In one aspect, a method includes forming a pit in a top surface of a substrate by removing a portion of the substrate and growing a semiconductor material with a bottom surface on the pit, the semiconductor material different than the material of the substrate. The pit has a base recessed in the top surface of the substrate. In another aspect, a structure includes a substrate having a top surface, the substrate including at least one pit having a base lower than the top surface of the substrate, and a semiconductor material having a bottom surface formed on the base of the pit.
    Type: Grant
    Filed: October 17, 2008
    Date of Patent: September 4, 2012
    Assignee: Sifotonics Technologies (USA) Inc.
    Inventors: Liang Chen, Chingyin Hong, Fuwan Gan, Dong Pan
