An integrated circuit chip is formed with a circuit layer, a trap rich layer and through-semiconductor-vias. The trap rich layer is formed above the circuit layer. The through-semiconductor-vias are also formed above the circuit layer. In some embodiments, the circuit layer is included in a wafer, and the trap rich layer and through-semiconductor-vias are included in another wafer. The two wafers are bonded together after formation of the trap rich layer and through-semiconductor-vias. Additionally, in some embodiments, yet another wafer may also be bonded to the wafer that includes the trap rich layer and through-semiconductor-vias. Furthermore, in some embodiments, another circuit layer may be formed in the wafer that includes the trap rich layer and through-semiconductor-vias.

Trap rich layer with through-silicon-vias in semiconductor devices

An integrated circuit assembly comprises an insulating layer, a semiconductor layer, a handle layer, a metal interconnect layer, and transistors. The insulating layer has a first surface, a second surface, and a hole extending from the first surface to the second surface. The semiconductor layer has a first surface and a second surface, the first surface of the semiconductor layer contacting the first surface of the insulating layer. The handle layer is coupled to the second surface of the semiconductor layer. The metal interconnect layer is coupled to the second surface of the insulating layer, the metal interconnect layer being disposed within the hole in the insulating layer. The transistors are located in the semiconductor layer. The hole in the insulating layer extends to at least the first surface of the semiconductor layer. The metal interconnect layer electrically couples a plurality of the transistors to each other.

Semiconductor-on-insulator integrated circuit with interconnect below the insulator

Semiconductor-on-insulator integrated circuit with reduced off-state capacitance

An integrated circuit chip is formed with an active layer and a trap rich layer. The active layer is formed with an active device layer and a metal interconnect layer. The trap rich layer is formed above the active layer. In some embodiments, the active layer is included in a semiconductor wafer, and the trap rich layer is included in a handle wafer.

Methods for the formation of a trap rich layer

An integrated circuit fabricated on a semiconductor-on-insulator transferred layer is described. The integrated circuit includes an interconnect layer fabricated on the back side of the insulator. This interconnect layer connects active devices to each other through holes etched in the insulator. This structure provides extra layout flexibility and lower capacitance, thus enabling higher speed and lower cost integrated circuits.

A thermal path is formed in a layer transferred semiconductor structure. The layer transferred semiconductor structure has a semiconductor wafer and a handle wafer bonded to a top side of the semiconductor wafer. The semiconductor wafer has an active device layer formed therein. The thermal path is in contact with the active device layer within the semiconductor wafer. In some embodiments, the thermal path extends from the active device layer to a substrate layer of the handle wafer. In some embodiments, the thermal path extends from the active device layer to a back side external thermal contact below the active device layer.
