Abstract: A thin film transistor includes an active layer and at least one gate stack. The active layer may be formed using multiple iterations of a unit layer stack deposition process, which includes an acceptor-type oxide deposition process and a post-transition metal oxide deposition process. A surface of each gate dielectric within the at least one gate stack contacts a surface of a respective layer of the oxide of the acceptor-type element so that leakage current of the active layer may be minimized. A source electrode and a drain electrode may contact an oxide layer providing lower contact resistance such as a layer of the post-transition metal oxide or a zinc oxide layer within the active layer.

Abstract: A semiconductor device includes a gate, a semiconductor structure, a gate insulating layer, a first source/drain feature and a second source/drain feature. The gate insulating layer is located between the gate and the semiconductor structure. The semiconductor structure includes at least one first metal oxide layer, a first oxide layer, and at least one second metal oxide layer. The first oxide layer is located between the first metal oxide layer and the second metal oxide layer. The first source/drain feature and the second source/drain feature are electrically connected with the semiconductor structure.

Abstract: Some embodiments relate to a thin film transistor comprising an active layer over a substrate. An insulator is stacked with the active layer. A gate electrode structure is stacked with the insulator and includes a gate material layer having a first work function and a first interfacial layer. The first interfacial layer is directly between the insulator and the gate material layer, wherein the gate electrode structure has a second work function that is different from the first work function.
