A method of forming a thin film poly silicon layer includes following steps. Firstly, a substrate is provided. A heating treatment is then performed. A thin film poly silicon layer is then directly formed on a first surface of the substrate by a silicon thin film deposition process. A method of forming a thin film transistor includes following steps. Firstly, a substrate is provided. A heating treatment is then performed. A thin film poly silicon layer is then directly formed on a first surface of the substrate by a silicon thin film deposition process. A first patterning process is performed on the thin film poly silicon layer to form a semiconductor pattern. Subsequently, a gate insulation layer, a gate electrode, a source electrode and a drain electrode are formed. |
