摘要:
A method for manufacturing a thin film transistor is provided. First, a poly-silicon island is formed on a substrate. Then, a patterned gate dielectric layer and a gate are formed on the poly-silicon island. Next, a source/drain is formed in the poly-silicon island beside the gate, wherein the region between the source/drain is a channel. Furthermore, a metal layer is formed on the substrate to cover the gate, the patterned gate dielectric layer and the poly-silicon island. Moreover, the metal layer above the source/drain will react with the poly-silicon island to form a silicide layer. Then, the non-reacted metal layer is removed. Afterwards, an inter-layer dielectric (ILD) is formed to cover the substrate. Then, the inter-layer dielectric above the source/drain is removed to form a source/drain contacting hole, wherein the silicide layer is used as an etching stopper.

An analog output buffer circuit for a flat panel display is provided for improving an output signal distortion. The circuit includes a transistor, a current source, an input capacitor, an upper switch, a lower switch, a first switch, a second switch and a third switch. In which, the transistor and the current source are electrically connected in series between a first power supply and a second power supply. The current source provides a compensatory current for the transistor when a leakage current occurs. The upper switch and the first switch are turned on during the first period, and the lower switch and the second switch are turn on during the second period, in which the second period is after the first period. Those switches eliminate the drawback of different voltage levels between the input signal and the output signal obtained from the output buffer circuit inputted by the input signal.
