Filed: 2000-11-13
Abstract: PROBLEM TO BE SOLVED: To reduce the frequency at which a film sticking to the inside surface of a plasma CVD chamber is removed, related to formation of an ohmic contact layer comprising an n-type amorphous silicon of a thin-film transistor. SOLUTION: Phosphorus films 54a and 54b whose film thickness is about several Å are formed on both surfaces of an upper surface of a channel protective film 35 and on the upper surface of a semiconductor thin-film 34 on both sides of it, and a drain electrode 42 and a source electrode 43 comprising chrome are formed on each upper surface.

The phosphorus films 54a and 54b are formed by a plasma CVD using a mixture gas of PH3 and H2. Here, since the very thin thickness of phosphorus films 54a and 54b is several Å, the stuck amount per film-forming is very small even if a phosphorus film sticks to the inside surface of the plasma CVD chamber.
