Process and equipment simulation of copper chemical vapor deposition using Cu(hfac)vtms
The numerical simulation of organometallic chemical vapor deposition (OMCVD) of copper films using copper(I) hexafluoroacetylacetonate vinyltrimethylsilane and argon was performed. For the solution of the fluid dynamic transport equations, we used the PHOENICS-CVD simulation tool, which includes the treatment of all relevant transport phenomena. Transport properties of the organic species were estimated using standard methods. Kinetic data were derived from deposition experiments. The model was applied to copper deposition in cold-wall single-wafer R&D equipment. The radial course of deposition rates and their dependence on wafer temperature were calculated and compared with deposition experiments. The simulation represents the main experimental trends and appears to be suitable for process and equipment optimization.
