Latest Patents

Yonezawa holds a patent for a method titled "Cyclic film deposition using reductant gas." This method involves depositing a film on a substrate within a processing chamber by repeating a cycle that includes a precursor step and a reactant step, along with potential purge steps. The process incorporates a reductant step, which is performed during part of the cycle. The precursor step exposes the substrate to a precursor gas, such as titanium tetrachloride, to form an intermediate film. The reactant step then involves exposing the substrate to a reactant gas, like hydrazine, to chemically react with the intermediate film. The reductant step utilizes a gas containing hydrogen, such as hydrogen gas, to enhance the deposition process. Yonezawa's innovative approach has the potential to improve film quality and deposition rates.
