    摘要: The formation of through silicon vias (TSVs) in an integrated circuit (IC) die or wafer is described in which the TSV is formed in the integration process prior to contact or metallization processing. Contacts and bonding pads may then be fabricated after the TSVs are already in place, which allows the TSV to be more dense and allows more freedom in the overall TSV design. By providing a denser connection between TSVs and bonding pads, individual wafers and dies may be bonded directly at the bonding pads. The conductive bonding material, thus, maintains an electrical connection to the TSVs and other IC components through the bonding pads.

    摘要: A stacked structure includes a first die bonded over a second die. The first die has a first die area defined over a first surface. At least one first protective structure is formed over the first surface, around the first die area. At least one side of the first protective structure has at least one first extrusion part extending across a first scribe line around the protective structure. The second die has a second die area defined over a second surface. At least one second protective structure is formed over the second surface, around the second die area. At least one side of the second protective structure has at least one second extrusion part extending across a second scribe line around the protective structure, wherein the first extrusion part is connected with the second extrusion part.

    摘要: A method for providing a stacked wafer configuration is provided. The method includes bonding a first wafer to a second wafer. A filler material is applied in a gap formed along edges of the first wafer and the second wafer. The filler material provides support along the edges during a thinning and transportation process to help reduce cracking or chipping. The filler material may be cured to reduce any bubbling that may have occurred while applying the filler material. Thereafter, the second wafer may be thinned by grinding, plasma etching, wet etching, or the like. In some embodiments of the present invention, this process may be repeated multiple times to create a stacked wafer configuration having three or more stacked wafers.

    摘要: A method for singulating semiconductor wafers is disclosed. A preferred embodiment comprises forming scrub lines on one side of the wafer and filling the scrub lines with a temporary fill material. The wafer is then thinned by removing material from the opposite side of the wafer from the scrub lines, thereby exposing the temporary fill material on the opposite side. The temporary fill material is then removed, and the individual die are removed from the wafer.
