A process for producing a metal oxide semiconductor (MOS) transistor is provided. At least two trenches are formed at a surface of a first substrate. Oxide is deposited onto the at least two trenches. The at least two trenches each have a surface spaced apart from the surface of the first substrate. A second substrate is placed onto the surface of the first substrate. A layer is delaminated from the first substrate. The layer includes the at least two oxide-filled trenches and a portion of the first substrate. The layer is then bonded to a second substrate. First and second active regions are then formed, in the portion of the first substrate, overlaying the surfaces of the at least two trenches.
