    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: Thin film transistor fabrication methods. A gate electrode is formed on a substrate. The surface of metal gate is subjected to a hydrogen plasma treatment to remove a native oxide formed thereon. A nitride layer as a buffer layer is formed to cover the metal gate. 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 prevents the metal gate from damage in subsequent plasma enhanced chemical vapor deposition processes.

    摘要: 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. A hydrogen plasma etching process is thereafter performed. The deposition process and the etching process are repeated for at least one time to form an interface layer. Finally, an amorphous silicon layer, n+ doped Si layers, a source electrode, and a drain electrode are formed on the interface layer.
