    摘要: A metal interconnection is prepared by forming an underlying metal film of high melting point metal such as Ti and/or high melting point metal compound such as TiN layers above a semiconductor substrate, plasma etching the surface of the underlying metal film in a gas atmosphere containing chloride, and forming an interconnecting metal film such as Al, Cu, Au and Ag on the underlying metal film. Alternatively, a metal interconnection is prepared by forming an insulating film above a semiconductor substrate, forming connecting holes in the insulating film, forming an underlying metal film such as TiN on the insulating film and the bottom and side wall of the connection holes by a CVD process under controlled conditions, and forming an interconnecting metal film such as Al on the underlying metal film. The TiN film has (111) preferential orientation and the aluminum film has (111) preferential orientation, smooth surface and effective coverage. The thus fabricated metal interconnection has improved reliability including electromigration immunity when used in semiconductor devices and finding advantageous use in miniaturized semiconductor devices.

    摘要: In a method of manufacturing an insulating film of a semiconductor device by a chemical vapor deposition, a surface of a semiconductor wafer is treated with an organic compound such as ethanol and methanol, and then the semiconductor wafer is transported into a reaction chamber and an insulating film is deposited on the thus treated surface of the semiconductor wafer by a chemical vapor deposition using a raw material such as organic silicon compound. By treating the surface of the semiconductor wafer with the organic compound prior to the deposition, the filling capability and planarization of the insulating film are improved. Further the insulating film thus formed is free from voids and clacks, and an amount of water contained in the insulating film is very small. The treatment of the surface of the semiconductor wafer can be performed simply by spin coating, spaying, vapor exposing or dipping, so that the throughput can be improved. Moreover, a gas of said organic compound for treating the surface of the semiconductor wafer may be mixed with raw material gas and reaction gas in the reaction chamber.
