Patent number: 8226805Abstract: An insoluble anode for metal wire electroplating capable of simultaneously electroplating a plurality of metal wires and uniformalizing the electroplating amounts of the metal wires stably for a long time. For realizing these, a plurality of insoluble electrode plates are disposed in a parallel alignment to be placed sandwiching a plurality of wire travel paths from both sides. A plurality of the insoluble electrode plates are tightened and fixed by through-bolts at a plurality of places along the travel path direction. A conductive spacer is interposed in each gap between the insoluble electrode plates at a tightening part by the through-bolt and also a conductive member is provided so as to contact all the electrode plates and the conductive spacers.Type: GrantFiled: June 29, 2007Date of Patent: July 24, 2012Assignees: Daiso Co., Ltd., Bridgestone CorporationInventors: Kenji Kawaguchi, Ryuichi Otogawa, Kenichi Murakami, Yuji Nakamura -
Patent number: 8216438Abstract: Provided is a copper anode or a phosphorous-containing copper anode for use in performing electroplating copper on a semiconductor wafer, wherein purity of the copper anode or the phosphorous-containing copper anode excluding phosphorous is 99.99 wt % or higher, and silicon as an impurity is 10 wtppm or less. Additionally provided is an electroplating copper method capable of effectively preventing the adhesion of particles on a plating object, particularly onto a semiconductor wafer during electroplating copper, a phosphorous-containing copper anode for use in such electroplating copper, and a semiconductor wafer comprising a copper layer with low particle adhesion formed by the foregoing copper electroplating.Type: GrantFiled: October 6, 2008Date of Patent: July 10, 2012Assignee: JX Nippon Mining & Metals CorporationInventors: Akihiro Aiba, Hirofumi Takahashi
