20130220796 | COMPOSITE TARGET AND METHOD FOR MANUFACTURING THE SAME - A composite target and method for manufacturing the same are described, which manufactures the composite target according an etching condition of a waste target. The waste target is generated after an original target at least haying a substrate layer and a metal layer is processed through a sputtering process by a sputtering apparatus with a first magnetic field line distribution. By determining the etching condition caused by the first magnetic field line distribution, a magnetic layer with a second magnetic field line distribution is decided to dispose on the original target. The metal layer is formed on the substrate layer and/or the magnetic layer. The substrate layer, the magnetic layer and the metal layer are combined by a connection layer to form the composite target. The composite target can provide the second magnetic field line distribution to adjust the first magnetic field line distribution. | 08-29-2013 |
