Abstract:
Embodiments of the present disclosure describe semiconductor devices comprised of a semiconductor substrate with a metal oxide semiconductor field effect transistor having a channel including germanium or silicon-germanium, where a dielectric layer is coupled to the channel. The dielectric layer may include a metal oxide and at least one additional element, where the at least one additional element may increase a band gap of the dielectric layer. A gate electrode may be coupled to the dielectric layer. Other embodiments may be described and/or claimed.
Abstract:
Ge and III-V channel semiconductor devices having maximized compliance and free surface relaxation and methods of fabricating such Ge and III-V channel semiconductor devices are described. For example, a semiconductor device includes a semiconductor fin disposed above a semiconductor substrate. The semiconductor fin has a central protruding or recessed segment spaced apart from a pair of protruding outer segments along a length of the semiconductor fin. A cladding layer region is disposed on the central protruding or recessed segment of the semiconductor fin. A gate stack is disposed on the cladding layer region. Source/drain regions are disposed in the pair of protruding outer segments of the semiconductor fin.
Abstract:
Techniques are disclosed for converting a strain-inducing semiconductor buffer layer into an electrical insulator at one or more locations of the buffer layer, thereby allowing an above device layer to have a number of benefits, which in some embodiments include those that arise from being grown on a strain-inducing buffer and having a buried electrical insulator layer. For instance, having a buried electrical insulator layer (initially used as a strain-inducing buffer during fabrication of the above active device layer) between the Fin and substrate of a non-planar integrated transistor circuit may simultaneously enable a low-doped Fin with high mobility, desirable device electrostatics and elimination or otherwise reduction of substrate junction leakage. Also, the presence of such an electrical insulator under the source and drain regions may further significantly reduce junction leakage. In some embodiments, substantially the entire buffer layer is converted to an electrical insulator.

Abstract:
Embodiments include a resistive random access memory (RRAM) storage cell, having a resistive switching material layer and a semiconductor layer between two electrodes, where the semiconductor layer serves as an OEL. In addition, the RRAM storage cell may be coupled with a transistor to form a RRAM memory cell. The RRAM memory cell may include a semiconductor layer as a channel for the transistor, and also shared with the storage cell as an OEL for the storage cell. A shared electrode may serve as a source electrode of the transistor and an electrode of the storage cell. In some embodiments, a dielectric layer may be shared between the transistor and the storage cell, where the dielectric layer is a resistive switching material layer of the storage cell.
Abstract:
Embodiments herein describe techniques for a semiconductor device including a TFT having a gate electrode with a gate length determined by a spacer. Embodiments may include a gate electrode above a substrate, a channel layer above the gate electrode, and a source electrode, a drain electrode, and a spacer above the channel layer. The drain electrode may be separated from the source electrode by the spacer. The drain electrode and the source electrode may have different widths or include different materials. Furthermore, the spacer may overlap with the gate electrode, hence the gate length of the gate electrode may be determined by the spacer width. Other embodiments may be described and/or claimed.

Embodiments of the present disclosure describe a non-planar gate thin film transistor. An integrated circuit may include a plurality of layers formed on a substrate, and the plurality of layers may include a first one of a source or drain, an inter-layer dielectric (ILD) formed on the first one of the source or drain, and a second one of the source or drain formed on the ILD. A semiconductive layer may be formed on a sidewall of the plurality of layers. A gate dielectric layer formed on the semiconductive layer, and a gate may be in contact with the gate dielectric layer.

Abstract:
Techniques are disclosed for forming transistor devices having reduced interfacial resistance in a local interconnect. The local interconnect can be a material having similar composition to that of the source/drain material. That composition can be a metal alloy of a group IV element such as nickel germanide. The local interconnect of the semiconductor integrated circuit can function in the absence of barrier and liner layers. The devices can be used on MOS transistors including PMOS transistors.
