摘要:
A method of fabricating a high mobility semiconductor metal oxide thin film transistor including the steps of depositing a layer of semiconductor metal oxide material, depositing a blanket layer of etch-stop material on the layer of MO material, and patterning a layer of source/drain metal on the blanket layer of etch-stop material including etching the layer of source/drain metal into source/drain terminals positioned to define a channel area in the semiconductor metal oxide layer. The etch-stop material being electrically conductive in a direction perpendicular to the plane of the blanket layer at least under the source/drain terminals to provide electrical contact between each of the source/drain terminals and the layer of semiconductor metal oxide material. The etch-stop material is also chemical robust to protect the layer of semiconductor metal oxide channel material during the etching process.
