    摘要: A method for fabricating integrated circuit (ICs) having through substrate vias (TSVs) includes forming active circuit elements on a semiconductor wafer and then forming a plurality of embedded vias through the top side of the wafer. A metal filler layer including a filler metal is deposited to fill the embedded vias. Chemical mechanical polishing (CMP) then forms a plurality of embedded TSVs that have polished top TSV surfaces having exposed filler metal. An electrically conductive hillock suppression structure is formed by forming a silicon or germanium doped region, or a silicide or germanicide at the polished top TSV surface or by forming a metal layer on the polished top TSV surface having a composition different from the filler metal. A dielectric layer is deposited on the semiconductor wafer including over the hillock suppression structure. The dielectric layer is removed over the polished top TSV surface to allow metal contact thereto.

    摘要: A method of forming stacked die devices includes attaching first semiconductor die onto a wafer to form a reconstituted wafer, and then bonding second semiconductor die onto the first semiconductor die to form a plurality of singulated stacked die devices on the wafer. A support tape is attached to a bottomside of the second semiconductor die. A dicing tape is attached to the wafer. The wafer is laser irradiated before or after attachment of the dicing tape at intended dicing lanes that align with gaps between the first semiconductor die to mechanically weaken the wafer at the intended dicing lanes, but not cut through the wafer. The dicing tape is pulled to cleave the wafer into a plurality of singulated portions to form a plurality of singulated stacked die devices attached to the singulated wafer portions by the dicing tape. The support tape is removed prior to cleaving.
