发明名称 Post-seed deposition process
摘要 A method involves pattern etching a photoresist that is located on a wafer that contains a deposited seed layer to expose portions of the seed layer, plating the wafer so that plating metal builds up on only the exposed seed layer until the plating metal has reached an elevation above the seed layer that is at least equal to a thickness of the seed layer, removing the solid photoresist, and removing seed layer exposed by removal of the photoresist and plated metal until all of the exposed seed layer has been removed.
