  • Patent number: 10717219
    Abstract: The purpose of the present invention is to make it possible to shorten the time required for a burr removal step and make it difficult for the burrs to detach from a sheet member in a step for removing the burrs together with the sheet member. For removal, by making the burrs to adhere to a pliable sheet member such as paper or nonwoven fabric that has been incorporated beforehand in the molding die and stripping the sheet member from the molding die, the burrs are removed together with the sheet member. The present invention is characterized in that in order to make it difficult for the burrs to detach from the sheet member during the stripping, a radiused shape with an arc-shaped cross-section is formed by the molding die on the areas surrounding the sections where the burrs adhere to the sheet member.

  • Patent number: 9773651
    Abstract: A high-purity copper sputtering target, wherein a Vickers hardness of a flange part of the target is in a range of 90 to 100 Hv, a Vickers hardness of an erosion part in the central area of the target is in a range of 55 to 70 Hv, and a crystal grain size of the erosion part is 80 ?m or less. This invention relates to a high-purity copper sputtering target that does not need to be bonded to a backing plate (BP), and aims to provide a high-purity copper sputtering target capable of forming a thin film having superior uniformity by enhancing a strength (hardness) of the flange part of the target, and reducing an amount of warpage of the target. Moreover, the uniformity of the film thickness is improved by adjusting the (111) orientation ratio of the erosion part and the flange part in the target.
