    摘要: A fabrication method of thin film transistor. A patterned gate is formed on an insulator substrate. A buffer layer is formed on the insulating substrate. The patterned gate is formed by plasma enhanced chemical vapor deposition (PECVD) using a mixture of silane, argon, nitrogen to serve as reactants at a temperature of approximately 20-200° C. A gate insulating layer is formed on the buffer layer. A semiconductor layer is formed on the gate insulating layer. A source/drain layer is formed on the semiconductor layer. The buffer layer protects the metal gate from damage during subsequent plasma enhanced chemical vapor deposition.

    摘要: A method for fabricating a thin film transistor is provided. A conductive layer is formed on a substrate. A patterned mask is formed on the conductive layer to cover a predetermined thin film transistor (TFT) area, and at least one portion of the conductive layer exposed by the patterned mask are removed. A laser is applied to form a laser hole in the patterned mask to expose a portion of the conductive layer and the laser hole substantially corresponds to a channel region of the predetermined TFT area. The exposed conductive layer is etched to form source and drain electrodes on opposite sides of the channel region.
