Patent ID: 7731833

Claim:
A method of processing a workpiece comprising an upper surface, a field region defined by the upper surface, and a cavity having a depth below the upper surface and having a width, the width being greater than the depth, the method comprising: contacting the workpiece with an electrolyte solution; contacting an electrode with the electrolyte solution; forming a conductive material comprising a conductor on the workpiece, wherein forming the conductive material includes electroplating the conductor from the electrolyte solution, wherein forming the conductive material comprises: forming a first portion of the conductive material in the field region, the first portion having a first thickness above the upper surface of the workpiece; and forming a second portion of the conductive material in the cavity, the second portion filling the cavity and having a second thickness above the upper surface of the workpiece, wherein the second thickness is greater than the first thickness; and after forming the conductive material, completely removing the conductive material from the field region, wherein, after the removing, parts of the second portion of the conductive material remain above the upper surface of the cavity.
