Abstract:
1. A method of processing a microelectronic workpiece including a semiconductor substrate having a plurality of microelectronic dies, the individual dies including integrated circuitry and a terminal electrically coupled to the integrated circuitry, the method comprising: forming a first opening in the substrate from a back side of the substrate toward a front side of the substrate and in alignment with the terminal, the first opening having a generally annular cross-sectional profile and separating an island of substrate material from the substrate, and wherein the island of substrate material has an upper surface that extends outwardly past the back side of the substrate; depositing an insulating material into at least a portion of the first opening; and removing the island of substrate material after depositing the insulating material and forming a second opening aligned with at least a portion of the terminal, wherein the second opening does not extend completely through the terminal.
