Patent ID: 10930791

Abstract:
In accordance with disclosed embodiments, there are provided systems, methods, and apparatuses for implementing bi-layer semiconducting oxides in a source/drain for low access and contact resistance of thin film transistors. For instance, there is disclosed in accordance with one embodiment a semiconductor device having therein a substrate; a bi-layer oxides layer formed from a first oxide material and a second oxide material, the first oxide material comprising a semiconducting oxide material and having different material properties from the second oxide material comprising a high mobility oxide material; a channel layer formed atop the substrate, the channel layer formed from the semiconducting oxide material of the bi-layer oxides layer; a high mobility oxide layer formed atop the channel layer, the high conductivity oxide layer formed from the high mobility oxide material of the bi-layer oxides layer; metallic contacts formed atop the high mobility oxide layer; a gate and a gate oxide material formed atop the high mobility oxide layer, the gate oxide material being in direct contact with the high mobility oxide layer; and spacers separating the metallic contacts from the gate and gate oxide material. Other related embodiments are disclosed.
