Patent ID: 7344755

Claim:
A method for processing microfeature workpieces, comprising: pretreating a surface of a process chamber before beginning a workpiece deposition process in the process chamber, the pretreating comprising: depositing a layer comprising polysilicon on the surface; and contemporaneously introducing a first pretreatment precursor and a second pretreatment precursor to the process chamber to deposit a pretreatment material on the surface of the process chamber, the first pretreatment precursor comprising titanium and the second pretreatment precursor comprising nitrogen; terminating introduction of the first pretreatment precursor to the process chamber and terminating introduction of the second pretreatment precursor to the process chamber; after terminating the introduction of the first and second pretreatment precursors, positioning a microfeature workpiece in the process chamber; and after positioning the microfeature workpiece in the process chamber, depositing a deposition product comprising titanium nitride on a surface of the microfeature workpiece in the workpiece deposition process, the workpiece deposition process comprising alternately introducing a quantity of a first deposition precursor and a quantity of a second deposition precursor to the process chamber, the first deposition precursor comprising titanium and the second deposition precursor comprising nitrogen.
