    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.
