  • Publication number: 20090280025
    Abstract: An object of the present invention is to provide a high-purity Ru alloy target for sputtering and its manufacturing method, which are capable of reducing harmful substances as much as possible, refining the crystal grains as much as possible so as to make the film thickness distribution during deposition to be uniform, and preventing deterioration in adhesiveness with an Si substrate, and which are suitable in forming a capacitor electrode material of a semiconductor memory, as well as a high-purity Ru alloy sputtered film obtained by sputtering this Ru alloy target. In order to achieve the foregoing object, the present invention provides a high-purity Ru alloy target, wherein the content of the platinum group elements excluding Ru is 15 to 200 and remnants are Ru and inevitable impurities.

  • Publication number: 20090107837
    Abstract: A method of recycling ruthenium (Ru) and Ru-based alloys comprises steps of: providing a solid body of Ru or a Ru-based alloy; segmenting the body to form a particulate material; removing contaminants, including Fe, from the particulate material; reducing the sizes of the particulate material to form a powder material; removing contaminants, including Fe, from the powder material; reducing oxygen content of the powder material to below a predetermined level to form a purified powder material; and removing particles greater than a predetermined size from the purified powder material. The purified powder material may be utilized for forming deposition sources, e.g., sputtering targets.
