Patent ID: 7112508

Claim:
A method of providing a conductive material in an opening, the method comprising: providing a substrate assembly having at least one surface; providing an opening defined through the surface of the substrate assembly, wherein the opening is defined by at least one surface; forming at least one conductive material within the opening on to at least one surface defining the opening and on at least a portion of the substrate assembly surface, wherein the at least one conductive material comprises at least one Group VIII metal; forming a support film over the at least one conductive material; forming a fill material over at least a portion of the support film, wherein the fill material at least fills the opening; removing at least the fill material outside of the opening by planarization; removing to support film outside of the opening, wherein removing the support film outside of the opening comprises removing the support film outside of the opening by planarization; removing the at least one conductive material outside of the opening, wherein removing the at least one conductive material outside of the opening comprises removing the at least one conductive material to at least the surface of the substrate assembly by at least one of wet etching and dry etching; removing the fill material within the opening; and removing the support film within the opening.
