Abstract: A back end of line device and method for fabricating a transistor device include a substrate having an insulating layer formed thereon and a channel layer formed on the insulating layer. A gate structure is formed on the channel layer. Dopants are implanted into an upper portion of the channel layer on opposite sides of the gate structure to form shallow source and drain regions using a low temperature implantation process. An epitaxial layer is selectively grown on the shallow source and drain regions to form raised regions above the channel layer and against the gate structure using a low temperature plasma enhanced chemical vapor deposition process, wherein low temperature is less than about 400 degrees Celsius.

Abstract: Heterojunction bipolar transistors are provided that include at least one contact (e.g., collector, emitter, and/or base) formed by a heterojunction between a crystalline semiconductor material and a doped non-crystalline semiconductor material layer. An interfacial intrinsic non-crystalline semiconductor material layer is present at the heterojunction between the crystalline semiconductor material and the doped non-crystalline semiconductor material layer. The presence of the interfacial intrinsic non-crystalline semiconductor material layer improves the surface passivation of the crystalline semiconductor material by reducing the interface defect density at the heterojunction.

Abstract: High resolution active matrix structures are fabricated using techniques applicable to flexible substrates. A backplane layer including active semiconductor devices is formed using a semiconductor-on-insulator substrate. The substrate is thinned using a layer transfer technique or chemical/mechanical processing. Driver transistors are formed on the semiconductor layer of the substrate along with additional circuits that provide other functions such as computing or sensing. Contacts to passive devices such as organic light emitting diodes may be provided by heavily doped regions formed in the handle layer of the substrate and then isolated. A gate dielectric layer may be formed on the semiconductor layer, which functions as a channel layer, or the insulator layer of the substrate may be employed as a gate dielectric layer.

Abstract: A circuit includes a first field effect transistor having a gate, a first drain-source terminal, and a second drain-source terminal; and a second field effect transistor having a gate, a first drain-source terminal, and a second drain-source terminal. The second field effect transistor and the first field effect transistor are of the same type, i.e., both re-channel transistors or both p-channel transistors. The second drain-source terminal of the first field effect transistor is coupled to the first drain-source terminal of the second field effect transistor; and the gate of the second field effect transistor is coupled to the first drain-source terminal of the second field effect transistor. The resulting three-terminal device can be substituted for a single field effect transistor that would otherwise suffer breakdown under proposed operating conditions.

Abstract: A method for forming a back-illuminated image sensor includes forming a higher doped crystalline layer on a crystalline substrate, growing a lower doped crystalline layer on the higher doped crystalline layer and forming a photodiode and component circuitry from the lower doped crystalline layer. Metallization structures are formed to make connections to and between components. The crystalline substrate is removed to expose the higher doped crystalline layer. An optical component structure is provided on an exposed surface of the higher doped crystalline layer to receive light therein such that the higher doped crystalline layer provides a passivation layer for the photodiode and the component circuitry.
