  • Patent number: 8138569
    Abstract: A guard ring structure for use in a semiconductor device. The guard ring structure includes a semiconductor layer stack having a first layer and a second layer on top of the first layer, gates structures formed in the first layer; and guard rings formed in the first layer. The second layer has a dopant concentration that is higher than the dopant concentration of the first layer. The gates and the guard rings are formed simultaneously using a single mask.
    Type: Grant
    Filed: October 7, 2010
    Date of Patent: March 20, 2012
    Assignee: Northrop Grumman Systems Corporation
    Inventors: John Victor D. Veliadis, Megan J. Snook
