Abstract:
1. An integrated circuit die, comprising: a device wafer portion having a face side surface, the device wafer portion comprising a semiconductor wafer portion and an interconnect portion, the interconnect portion having a surface that is the face side surface of the device wafer, the semiconductor wafer portion comprising a source region of a first conductivity type, a drain region of the first conductivity type and a channel structure of a second conductivity type opposite the first conductivity type, wherein the source region, the drain region and the channel structure are parts of a single layer of a semiconductor material and together form an island of the semiconductor material; and a supporting structure portion that is bonded to the face side surface of the device wafer portion; wherein the island extends outward from a back side surface of the interconnect portion opposite the face side surface of the device wafer portion, and wherein at least one surface of the island substantially normal to the back side surface of the interconnect portion is exposed.
