Abstract:
1. A system, comprising: a deposition chamber; a solid material disposed within the deposition chamber; a silicon wafer disposed within the deposition chamber; a titanium-based film deposited on the silicon wafer as a result of a chemical reaction between hydrogen and a titanium source gas within the deposition chamber; and halide-based contaminants within the deposition chamber as a result of the chemical reaction, wherein the solid material has a greater affinity for the halide-based contaminants than the titanium-based film and wherein a sufficient amount of the halide-based contaminants is adsorbed in the solid material to cause the titanium-based film to have a halide-based contaminant content of less than 1%.
