Patent attributes
A method of fabricating self-aligned metal oxide TFTs on transparent flexible substrates is disclosed and includes the steps of providing a transparent flexible substrate with at least an opaque first metal TFT electrode in a supporting relationship on the front surface of the substrate and a layer of transparent material, including at least one of a metal oxide semiconductor and/or a gate dielectric, on the front surface of the substrate and the first metal TFT electrode. A layer of photoresist is positioned in overlying relationship to the layer of transparent material. Dual photo masks are positioned over the front and rear surfaces of the substrate, respectively, and the layer of photoresist is exposed. The layer of photoresist is developed and used to form a layer of second metal.
