Abstract:
1. A method for processing a microelectronic substrate, comprising: forming an aperture in a substrate material plane of a microelectronic substrate; disposing a conductive material on the microelectronic substrate and in the aperture, the conductive material having a conductive material plane external to the aperture and offset from the substrate material plane; disposing a fill material on the microelectronic substrate and in the aperture, the fill material having a fill material plane external to the aperture and offset from the substrate material plane and the conductive material plane; removing at least part of the fill material external to the aperture recessing the fill material inwardly from the conductive material plane toward the aperture; removing at least part of the conductive material external to the aperture so that the fill material projects away from the aperture beyond the substrate material plane; and disposing a microelectronic feature in the aperture.
