Abstract:
A method for making a plurality of silicon oxide insulator (SOI) devices, comprising the steps of:disposing at least one SOI layer on at least one silicon substrate;supporting a first body region on the SOI layer, the first body region being characterized by a first conductivity type;juxtaposing at least source and drain regions with the first body region, the source and drain regions being characterized by a second conductivity type;supporting a second body region on the SOI layer, the second body region being characterized by the first conductivity type;disposing a transition region near the first body region and the second body region above the SOI layer, the transition region being characterized by a transition conductivity type, the transition conductivity type being established to be the first conductivity type for suppressing floating body effects in the first body region and the second body region by linking the first body region and the second body region;supporting a third body region on the SOI layer;supporting a fourth body region on the SOI layer; anddisposing a second transition region near the third body region and the fourth body region above the SOI layer, wherein the third body region and the fourth body region have the same conductivity type, and the second transition region has a conductivity type which is opposite from the conductivity type of the third body region and the fourth body region so that the second transition region isolates the third body region from the second body region so that the third body region exhibits a floating effect.
