摘要： The present invention relates to a method for recycling a tantalum coil for sputtering that is disposed between a substrate and a sputtering target. The method for recycling a tantalum coil for sputtering is characterized in that the whole or partial surface of a spent tantalum coil is subject to cutting (cutting is performed until a re-deposited film and knurling traces are eliminated) so as to eliminate the re-deposited film that was formed during sputtering, and knurling is newly performed to the cut portion. While sputtered grains are accumulated (re-deposited) on the surface of the tantalum coil disposed between the substrate and the sputtering target during sputtering, by eliminating the sputtered grains accumulated on the spent coil by way of cutting after the sputtering is complete, the tantalum coil can be efficiently recycled. Thus, provided is technology capable of lean manufacturing of new coils, improving productivity, and stably providing such coils.
摘要翻译：本发明涉及设置在基板和溅射靶之间的用于再循环用于溅射的钽线圈的方法。用于再循环用于溅射的钽线圈的方法的特征在于，废钽线圈的整个或部分表面被切割（进行切割直到重新淀积的膜和滚花痕迹被消除），以便消除重新在溅射期间形成的沉积膜，并且对切割部分新进行滚花。当在溅射期间溅射的晶粒在设置在衬底和溅射靶之间的钽线圈的表面上积累（重新沉积）时，通过在溅射完成之后通过切割消除积聚在废线圈上的溅射晶粒，钽线圈可以有效回收。因此，提供了能够精密制造新线圈的技术，提高生产率并稳定地提供这种线圈。
