Abstract:
A process for depositing titanium aluminum or tantalum aluminum thin films comprising nitrogen on a substrate in a reaction space can include at least one deposition cycle. The deposition cycle can include alternately and sequentially contacting the substrate with a vapor phase Ti or Ta precursor and a vapor phase Al precursor. At least one of the vapor phase Ti or Ta precursor and the vapor phase Al precursor may contact the substrate in the presence of a vapor phase nitrogen precursor.

Claim (Index 2):
A process for depositing a metal aluminum thin film comprising nitrogen and having a work function of less than 4.5 eV on a substrate in a reaction space, the process comprising at least one deposition cycle comprising alternately and sequentially contacting the substrate with a vapor phase metal precursor and a vapor phase aluminum precursor comprising tritertbutylaluminum (TTBA), wherein at least one of the vapor phase metal precursor and the vapor phase aluminum precursor contacts the substrate in the presence of a vapor phase nitrogen precursor comprising N 2 , and wherein the metal aluminum thin film comprises at least 5% nitrogen on an atomic basis.
