Patent ID: 10497725

Abstract:
A method includes a conductive film forming process of forming a conductive film 51 covering a gate insulation film IS and a semiconductor film 42, the gate insulation film 45 covering a gate electrode 37G and a gate line 35G formed on a glass substrate 32 and the semiconductor film 42 formed on the gate insulation film 45 while overlapping the gate electrode 37G, a first etching process of etching the conductive film 51 and forming a source conductive film 46S connected to the semiconductor film 42 and a drain conductive film 46D connected to the semiconductor film 42, a resist forming process performed after the first etching process and forming a resist 53R covering the semiconductor film 42, the source conductive film 46S, and the drain conductive film 46D, and a second etching process performed after the resist forming process and performing etching for removing the conductive film 51 while using the resist 53R as a mask.
