Patent number: 10156019Abstract: Disclosed are an electrodeposition system and method with an anode assembly comprising a capacitor comprising a first conductive plate (i.e., an anode) with a frontside having a surface exposed to a plating solution, a second conductive plate on a backside of the first conductive plate, and a dielectric layer between the two conductive plates. During a non-plating mode, a power source, having positive and negative terminals connected to the first and second conductive plates, respectively, is turned on, thereby polarizing the first conductive plate (i.e., the anode) relative to the second conductive plate to prevent degradation of the anode and/or plating solution. During an active plating mode, another power source, having positive and negative terminals connected to the first conductive plate (i.e., the anode) and a cathode, respectively, is turned on, thereby polarizing the anode relative to the cathode in order to deposit a plated layer on a workpiece.Type: GrantFiled: November 3, 2017Date of Patent: December 18, 2018Assignees: International Business Machines Corporation, Ancosys GmbHInventors: Charles L.

Patent number: 8528593Abstract: Method for carrying out a bleed and feed of process solutions in a process tank. The feed solution is pumped out of a first tank into a first receiving space. The first receiving space is subsequently emptied into the process tank of with a pump. The volume of delivered feed solution in the process tank is measured. The bleed solution is pumped from the process tank with a pump into a second receiving space. The volume of delivered bleed solution in the second receiving space is measured. The bleed solution in the second receiving space is subsequently emptied into the second tank. The first receiving space differs from the second receiving space. A correction factor is calculated by comparing the measured and calculated volumes of the bleed and feed solution delivered by the pumps, with which correction factor the nominal delivery volume of the pumps are corrected in the next cycle.Type: GrantFiled: January 18, 2011Date of Patent: September 10, 2013Assignee: ancosys GmbHInventor: Juerg Stahl
