Abstract:
1. A method of manufacturing a thin film transistor device that includes a p-type thin film transistor and an n-type thin film transistor, the method comprising: (a) forming a first semiconductor film that is an active layer of said n-type thin film transistor and a second semiconductor film that is an active layer of said p-type thin film transistor such that their edges have slanted portions, respectively; (b) forming a resist film on said first semiconductor film so as to expose said slanted portions and so as to cover said second semiconductor film in its entirety; (c) performing half exposure of said resist film formed on said first semiconductor film to reduce a film thickness thereof; (d) injecting a p-type impurity only into said slanted portions of said first semiconductor film; (e) removing said resist film formed on said first semiconductor film; and (f) injecting the p-type impurity into said first semiconductor film in its entirety.
