Patent ID: 6879029

Claim:
A semiconductor device comprising: a semiconductor chip including: a semiconductor layer having a principle surface and a back surface, the back surface of the semiconductor layer corresponding to a back side of the semiconductor chip, wherein the semiconductor layer has a thickness that is several micrometers to at most about 20 micrometers; a semiconductor element region located within the semiconductor layer, wherein a semiconductor element is formed in the semiconductor element region; an isolation region located within the semiconductor layer to laterally isolate the semiconductor element region from another semiconductor region within the semiconductor layer, the isolation region comprising: a trench surrounding the semiconductor element region and formed within the semiconductor layer from the principal surface to the back surface, the back side of the semiconductor chip exposing a bottom portion of the trench; and a buried material filling the trench; and a supporting member attached to the back side of the semiconductor chip through an adhesive, wherein the supporting member has sidewalls that are coplanar with sidewalls of the semiconductor chip.
