ABSTRACT:
A method for forming an in-situ doped amorphous or polycrystalline silicon thin film on a substrate is provided. The method includes placing the substrate in a reaction chamber of a CVD reactor and introducing a silicon gas species into the reaction chamber. The flow of the silicon gas species is continued for a time period sufficient to dehydrate the substrate and form a thin layer of silicon. Following formation of the thin layer of silicon, a dopant gas species is introduced into the reaction chamber and continued with the flow of the silicon gas species to form the doped silicon thin film. In an illustrative embodiment a phosphorus doped amorphous silicon thin film for a cell plate of a semiconductor capacitor is formed in a LPCVD reactor.
