Abstract
A transparent conductive film formed on a transparent substrate of a thin film transistor or solar cell contains an element falling in Group III or V of the periodic table. The transparent conductive film is formed in contact with a semiconductor layer.
Claims4
A laminate of a transparent conductive film and a semiconductor layer, said transparent conductive film being an ITO film containing phosphorus and being formed on an insulating substrate, said semiconductor layer being formed on said ITO film through a plasma assisted chemical vapor deposition process, at least the surface area of said semiconductor layer in contact with said ITO film containing phosphorus to form an ohmic contact layer.
A thin film transistor comprising source and drain electrodes of an ITO film containing phosphorus and formed on an insulating substrate, a semiconductor layer partly in contact with said source and drain electrodes and forming an active region of said thin film transistor, said semiconductor layer being formed through a plasma assisted chemical vapor deposition process, surface areas of said semiconductor layer in contact with said ITO film containing phosphorus to form an ohmic layer.
