Abstract: Embodiments of the present disclosure are contact structures for thin film transistor (TFT) devices. One embodiment is a TFT device comprising: a substrate; a gate formed above the substrate; a TFT channel formed above the substrate; and a pair of contacts formed on the TFT channel, wherein each of the contacts comprises one or more layers including: a metal that is non-reactive with a material of the TFT channel; or a plurality of layers including a first metal layer formed on a second layer, the second layer in contact with the TFT channel and between the first mater layer and the TFT channel. Other embodiments may be disclosed and/or claimed.

Abstract: Embodiments herein describe techniques for a semiconductor device including a transistor. The transistor includes a first metal contact as a source electrode, a second metal contact as a drain electrode, a channel area between the source electrode and the drain electrode, and a third metal contact aligned with the channel area as a gate electrode. The first metal contact may be located in a first metal layer along a first direction. The second metal contact may be located in a second metal layer along the first direction, in parallel with the first metal contact. The third metal contact may be located in a third metal layer along a second direction substantially orthogonal to the first direction. The third metal layer is between the first metal layer and the second metal layer. Other embodiments may be described and/or claimed.

Abstract: In accordance with disclosed embodiments, there are provided systems, methods, and apparatuses for implementing a high mobility low contact resistance semiconducting oxide in metal contact vias for thin film transistors. For instance, there is disclosed in accordance with one embodiment an oxide semiconductor transistor, having therein: a substrate layer; a channel layer formed atop the substrate; a metal gate and a gate oxide material formed atop the semiconducting oxide material of the channel layer; spacers positioned adjacent to the gate and gate oxide material; a dielectric layer formed atop the channel layer, the dielectric layer encompassing the spacers, the gate, and the gate oxide material; contact vias opened into the dielectric material forming an opening through the dielectric layer to the channel layer; a high mobility liner material lining the contact vias and in direct contact with the channel layer, the high mobility liner formed from a high mobility oxide material; and metallic contact material filling the contact vias opened into the dielectric material and separated from the channel layer by the high mobility liner of the contact vias. Other related embodiments are disclosed.
