    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.

    摘要: A method of fabricating through silicon via (TSV) die includes depositing a first dielectric layer on a substrate that includes a plurality of TSV die. The TSV die have a topside including active circuitry, a bottomside, and a plurality of TSVs including an inner metal core that reaches from the topside to protruding TSV tips that extend out from the bottomside. The first dielectric layer covers the TSV tips. A portion of the first dielectric layer is removed to expose the TSV tips. At least one metal layer is deposited on the TSV tips to form metal caps on the TSV tips to provide metal capped TSV tips. A second dielectric layer is deposited on the bottomside of the substrate to cover the metal capped TSV tips. A portion of the second dielectric layer is removed to expose a portion of the metal capped TSV tips.

    摘要: In a semiconductor device for use in a wafer level chip scale package (WLCSP) and a method for fabrication, an inner scribe seal is formed around a functional circuit area that does not extend all the way into the corners of the rectangular die, and an outer scribe seal follows the perimeter of the die and into the corners, with the outer scribe seal having a continuous barrier wall towards the die edges so that moisture penetration in dielectric layers of the die is minimized, and cracks and delamination are stopped near the die edges. Limiting the extent of the insulating layer or layers in the WLCSP to cover the functional circuit area also reduces the stresses caused by these layers near the die corners.

    摘要: In a method for fabricating a semiconductor device a redundant scribe seal structure is formed. The semiconductor device includes a die having a rectangular shape with sloped corners. A scribe seal is formed to surround the die, the scribe seal having sides to form sloped corners that match the sloped corners of the die. A scribe seal extension having sharp corners is formed by extending the sides of the scribe seal that have a perpendicular orientation towards one another. The scribe seal extension redundantly encloses a corresponding one of the sloped corners of the scribe seal.
