Latest Patents

Wuwen Yi holds a patent for a methodology that focuses on recycling ruthenium (Ru) and Ru-based alloys. The patent outlines a comprehensive process that includes providing a solid body of Ru or a Ru-based alloy, segmenting the body to create a particulate material, and removing contaminants such as iron (Fe) from the particulate material. The process further involves reducing the sizes of the particulate material to form a powder, purifying the powder by reducing its oxygen content, and ensuring that only particles below a predetermined size are retained. This purified powder material can then be utilized for forming deposition sources, such as sputtering targets.
