Patent ID: 8431932

Claim:
A thin-film transistor structure, comprising: a substrate; a transparent layer having a recess filled with a first metal layer and a first barrier layer which is sandwiched in between the first metal layer and the transparent layer; an insulated layer formed on the first metal layer; a semi-conductive layer formed on the insulated layer, wherein the insulated layer and semi-conductive layer have the same pattern from a top view with respect to the recess where the first metal layer and a first barrier layer been filled therein; a source metal layer and a drain metal layer formed on the part edge of the semi-conductive layer, wherein the source metal layer and the drain metal layer include a multilayer structure of TiN/Al—Cu alloy/Ti or TiN/Al—Si—Cu alloy/Ti; and a transparent electrode layer formed on the part transparent layer and the part drain metal layer which electrically connects with the transparent electrode layer.
