Abstract:
1. A body biasing structure for Silicon-On-Insulator (SOI) devices comprising: an SOI substrate; an active region in the SOI substrate comprising: a first conducting layer, which is formed on an insulating layer over both one part of the body biasing contact region and one part of the common active region; a second conducting layer, which is formed on an insulating layer over the device active region; a source region, which is formed in the other part of the common active region, over which the first conducting layer is not formed; a common source/drain region, which is formed in the device active region between the first conducting layer and the second conducting layer; and a body region, which is formed in the active region, where the source region and the common source/drain region are not formed, wherein the common source/drain region has a shallow junction to enable the second conducting layer to body bias through a body contact, which is formed on the body biasing contact region.
