Abstract: 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.

Abstract: Methods and apparatuses for fabricating thin film transistors. An apparatus comprises a first chamber and a second chamber. A substrate comprising a metal gate formed thereon is brought into the first chamber to form a passivation layer on the metal gate. The substrate is then transported to the second chamber to form a gate insulating layer and a semiconductor layer on the passivation layer. Accordingly, the second chamber experiences no metal contamination resulting from the metal gate.

Abstract: A method for forming a thin film transistor on a substrate is disclosed. A gate electrode and a gate insulation layer are disposed on a surface of the substrate. A deposition process is performed by utilizing hydrogen diluted silane to form a silicon-contained thin film on the gate insulation layer first.

Finally, an amorphous silicon layer, n+ doped Si layers, a source electrode, and a drain electrode are formed on the interface layer.
