    摘要: A method for depositing metal layers on semiconductor substrates by a thermal chemical vapor deposition (TCVD) process includes introducing a process gas containing a metal carbonyl precursor in a process chamber and depositing a metal layer on a substrate. The TCVD process utilizes a short residence time for the gaseous species in the processing zone above the substrate to form a low-resistivity metal layer. In one embodiment of the invention, the metal carbonyl precursor can be selected from at least one of W(CO)6, Ni(CO)4, Mo(CO)6, Co2(CO)8, Rh4(CO)12, Re2(CO)10, Cr(CO)6, and Ru3(CO)12 precursors. In another embodiment of the invention, a method is provided for depositing low-resistivity W layers at substrate temperatures below about 500° C., by utilizing a residence time less than about 120 msec.

    摘要: The present invention provides a CVD apparatus and a CVD method for use in forming an Al/Cu multilayered film. The Al/Cu multilayered film is formed in the CVD apparatus comprising a chamber for placing a semiconductor wafer W, a susceptor for mounting the semiconductor wafer W thereon, an Al raw material supply system for introducing a gasified Al raw material into the chamber and a Cu raw material supply system for introducing a gasified Cu raw material into the chamber. The Al/Cu multilayered film is formed by repeating a series of steps consisting of introducing the Al raw material gas into the chamber, depositing the Al film on the semiconductor wafer W by a CVD method, followed by generating a plasma in the chamber in which the Cu raw material gas has been introduced and depositing the Cu film on the semiconductor wafer W by a CVD method. The Al/Cu multilayered film thus obtained is subjected to a heating treatment (annealing), thereby forming a desired Al/Cu multilayered film.

    摘要: A substrate is disposed in a processing chamber. An organic Ta compound gas having Ta═N bond, a Si-containing gas and a N-containing gas are introduced into the processing chamber to form a TaSiN film on the substrate by CVD. In this film formation, at least one of a partial pressure of the Si-containing gas in the processing chamber, a total pressure in the processing chamber, a film forming temperature and a partial pressure of the N-containing gas in the processing chamber is controlled to thereby regulate Si concentration in the film. Particularly, when SiH4 gas is used as the Si-containing gas, the SiH4 gas partial pressure is determined based on the fact that the serried Si concentration in the film under giving process conditions can be expressed as a linear function involving the logarithm of the partial pressure of the SiH4 gas.

    摘要: On a Si substrate 1, i.e., a semiconductor substrate, a gate insulating film 2 is formed, and then a W-based film 3a is formed on the gate insulating film 2 by CVD using a film forming gas including W(CO)6 gas. Then, the film is oxidized under existence of a reducing gas, and the W in the W-based film 3a is not oxidized but only C is selectively oxidized to reduce the concentration of C contained in the W-based film 3a. Then, after performing heat treatment as needed, resist coating, patterning, etching and the like are performed, and, an impurity diffused region 10 is formed by ion implantation and the like, and a semiconductor device having a MOS structure is formed.
