In atomic layer deposition (ALD) process, selecting the right precursor is critical for process control and film performance, etc. Meanwhile, based on the precursor properties such as volatility and reactivity, matching the right canister will have a synergistic effect on the process. Through high quality control of the material selection to the molding process, CSR Series Canister Assemblies can accommodate the packaging and storage of most precursors and provide excellent safety and cleanliness for the entire deposition process.
