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 system and method for stacking semiconductor dies is disclosed. A preferred embodiment comprises forming through-silicon vias through the wafer, protecting a rim edge of the wafer, and then removing the unprotected portions so that the rim edge has a greater thickness than the thinned wafer. This thickness helps the fragile wafer survive further transport and process steps. The rim edge is then preferably removed during singulation of the individual dies from the wafer.

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.
