Patent ID: 7514748

Claim:
An integrated circuit device, disposed on or in a first semiconductor region or layer which resides on or above an insulating region or layer, wherein the insulating region or layer is disposed on or over a substrate, the integrated circuit device comprising: a first portion including a plurality of transistors, wherein each transistor includes: a source region disposed on or in the first semiconductor region; a drain region disposed on or in the first semiconductor region; a body region disposed on or in the first semiconductor region and between the source region, the drain region, and the insulating region or layer, wherein the body region is electrically floating; a gate disposed over the body region; and a second portion including a plurality of transistors, wherein each transistor includes: a source region disposed in or on the first semiconductor region; a drain region disposed in or on the first semiconductor region; a body region disposed in or on the first semiconductor region and between the source region, the drain region, and the insulating region or layer; a gate disposed over the body region; and wherein the integrated circuit device further includes a second semiconductor region or layer disposed on or in the substrate and juxtaposed the body region of each transistor of the first portion of the integrated circuit device and separated therefrom by the insulating region or layer, and wherein the second semiconductor region or layer is not disposed on or in a portion of the substrate juxtaposed the body region of each transistor of the second portion of the integrated circuit device.
