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： A metal film with a lowered resistance by controlling a crystal structure. A tungsten film is formed through a first tungsten film formation in which a first tungsten film with amorphous content is formed by alternately executing multiple times a supplying a metal base material gas such as WF6 gas and supplying a hydrogen compound gas such as SiH4 gas, with a purge executed between the two gas supply by supplying an inert gas such as Ar gas or N2 gas and a second tungsten film formation in which a second tungsten film is formed by simultaneously supplying the WF6 gas and a reducing gas such as H2 gas onto the first tungsten film. The amorphous content in the first tungsten film is controlled by adjusting the length of time over which the purge is executed following the SiH4 gas supply.

摘要： An insulating film consisting of first and second tantalum oxide layers is formed on a semiconductor wafer. First, an amorphous first layer is formed by CVD, and a reforming process for removing organic impurities contained in the first layer is carried out. Then, an amorphous second layer is formed by CVD on the first layer. Then, a reforming process for removing organic impurities contained in the second layer is carried out by supplying a process gas containing ozone into a process chamber while heating the wafer to a temperature lower than a crystallizing temperature over a certain period. Further, within the same process chamber, the wafer is successively heated to a second temperature higher than the crystallizing temperature, followed by cooling the wafer to a temperature lower than the crystallizing temperature so as to crystallize the first and second layers simultaneously.
