Abstract:
1. A thin film semiconductor device comprising: a semiconductor layer; source/drain electrodes positioned in communication with the semiconductor layer and defining a conductive channel in the semiconductor layer; a gate electrode in communication with the conductive channel and positioned to control conduction of the channel; the semiconductor layer including an amorphous insulating covalent metal oxide material and an amorphous semiconductor ionic metal oxide material; the amorphous insulating covalent metal oxide material and the amorphous semiconductor ionic metal oxide material being mixed in a predetermined ratio that forms a continuous network of the amorphous semiconductor ionic metal oxide material and prevents the amorphous semiconductor ionic metal oxide material from becoming poly crystalline at processing temperatures; the mixture of the amorphous insulating covalent metal oxide material and the amorphous semiconductor ionic metal oxide material being deposited in an orientation supported by a substrate in one of a top gate bottom source/drain electrodes; top gate top source/drain electrodes; bottom gate bottom source drain electrodes; and bottom gate top source drain configuration electrodes; and the mixture of the amorphous insulating covalent metal oxide material and the amorphous semiconductor ionic metal oxide material having a carrier concentration determined by one of oxygen and nitrogen being included during the deposition.
