20090139871 | Plating apparatus and plating method - A plating apparatus can form a bump having a flat top or can form a metal film having a good in-plane uniformity even when the plating of a plating object (substrate) is carried out under high-current density conditions. The plating apparatus includes a plating tank for holding a plating solution; an anode to be immersed in the plating solution in the plating tank; a holder for holding a plating object and disposing the plating object at a position opposite the anode; a paddle, disposed between the anode and the plating object held by the holder, which reciprocates parallel to the plating object to stir the plating solution; and a control section for controlling a paddle drive section which drives the paddle. The control section controls the paddle drive section so that the paddle moves at a velocity whose average absolute value is 70 cm/sec to 100 cm/sec. | 06-04-2009 |
20090242413 | Electroplating Head and Method for Operating the Same - An electroplating head is disposed above and proximate to an upper surface of a wafer. Cations are transferred from an anode to an electroplating solution within the electroplating head. The electroplating solution flows downward through a porous electrically resistive material at an exit of the electroplating head to be disposed on the upper surface of the wafer. An electric current is established between the anode and the upper surface of the wafer through the electroplating solution. The electric current is uniformly distributed by the porous electrically resistive material present between the anode and the upper surface of the wafer. The electric current causes the cations to be attracted to the upper surface of the wafer. | 10-01-2009 |

20150299865 | METAL TREATMENT - Metal objects are treated by anodising (P, SE) the metal object in contact with an acidic solution, and then subjecting the anodised metal object to a reversed voltage (VR). The anodising is performed in two stages, firstly to passivate (P) with the formation of a surface layer, and secondly to form pits in this surface layer (SE). The second stage (SE) of anodising is performed at a lower voltage than the first stage (P). After the reversed voltage step (VR) the metal object is then contacted with a biocidal metal-containing solution. Biocidal metal is absorbed into the surface of the metal object, resulting in improved biocidal properties. The lower voltage of the second stage anodising (SE) results in reduced processing time. | 10-22-2015 |
