摘要:
An embodiment of the instant invention is a method of depositing a TiN-based film over a semiconductor wafer, the method comprising the steps of: substantially simultaneously subjecting the semiconductor wafer to TiCl 4 , H 2 , and N 2 ; and subjecting the semiconductor wafer to a plasma, such that the combination of the TiCl 4 , H 2 , and N 2 and the plasma cause the deposition of a TiN based film to form over the semiconductor wafer. Another embodiment of the instant invention involves additionally subjecting the semiconductor wafer to SiH 4 so as to form a TiSi x N y film over the semiconductor wafer. Another embodiment of the instant invention involves additionally subjecting the semiconductor wafer to B 2 H 6 so as to form a TiN x B y layer over the semiconductor wafer.
