Method for manufacturing a read head having conductive filler in insulated hole through substrate

Abstract

A method for manufacturing a read head includes the step of depositing a conductive filler into a plurality of holes that extend through a wafer. Each of the holes extends from a wafer top surface to a wafer bottom surface. Each of the holes includes an inner surface that includes an insulative layer. The method further includes the steps of fabricating a read transducer on the wafer top surface, and depositing a plurality of electrically conductive leading connection pads on the wafer bottom surface. The plurality of electrically conductive leading connection pads are in electrical contact with the conductive filler.
