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.
