Chemical vapor deposition of Ti-Si-N films for diffusion barrier applications
- and others
Structurally disordered refractory ternary films such as titanium silicon nitride (Ti-Si-N) have potential as advanced diffusion barriers in future ULSI metallization schemes. The authors demonstrate chemical vapor deposition (CVD) of Ti-Si-N-containing films in a commercially available single-wafer CVD system using two different Ti precursors, TiCl{sub 4} and tetrakis(diethylamino)titanium (TDEAT). In particular, the TDEAT-based films can be grown conformally with low impurity content, and are promising candidates for advanced diffusion barrier applications.
