Abstract: Disclosed is a process of annealing through silicon vias (TSVs) or other deeply buried metallic interconnects using a back side laser annealing process. The process provides several advantages including sufficient grain growth and strain relief of the metal such that subsequent thermal processes do not cause further grain growth; shorter anneal times thereby reducing cycle time of 3D device fabrication; and reduced pattern sensitivity of laser absorption.

Abstract: A method of forming through silicon vias (TSVs) on integrated circuit (IC) chips and the IC chips. A TSV pattern on a stack of wiring layers on the surface of the IC chip identifies TSV locations. Etching the IC chip TSV pattern opens a cup shaped through hole through the stack to the silicon substrate at each TSV pattern location. The etched stack forms a TSV hard mask open (HMO) for the silicon substrate. Via through holes etched through the silicon substrate masked by the HMO are filled with conductor connecting IC circuits, e.g., to signal lines on the bottom of the chip.
