摘要： A first substrate has a source material forming surface on which source materials for forming a polymerized film is formed in a predetermined pattern, and a second substrate has a film forming surface on which the polymerized film will be formed. Here, the first substrate and the second substrate are installed in a processing chamber such that the source material forming surface and the film forming surface face each other. Then, the first substrate is heated to a first temperature at which the source materials on the source material forming surface are evaporated and the second substrate is heated to a second temperature at which the source materials cause polymerization reaction on the film forming surface. Therefore, the polymerized film is formed on the film forming surface by reacting the source materials and evaporated from the first substrate on the film forming surface of the second substrate.

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.
