Abstract:
A thin film transistor, consisting ofa substrate composed of low-temperature plastic, said low-temperature plastic substrate being not capable of withstanding sustained processing temperatures greater than about 250Â° C. an insulating layer of SiO2 on the plastic, a layer of silicon on the insulating SiO2 layer, said layer of silicon being composed of sections of doped silicon and undoped silicon, said layer of silicon including sections of poly-silicon, a gate dielectric layer of SiO2 on at least a section of the layer of silicon, a layer of gate metal on at least a section of the gate dielectric layer of SiO2, a layer of oxide on sections of said layer of silicon and said layer of gate metal, and metal contacts on sections of said layer of silicon and said layer of gate metal, defining source, gate, and drain contacts and interconnects.
