  • Patent number: 9799694
    Abstract: A wafer thinning system and method are disclosed that includes grinding away substrate material from a backside of a semiconductor device. A current change is detected in a grinding device responsive to exposure of a first set of device structures through the substrate material, where the grinding is stopped in response to the detected current change. Polishing repairs the surface and continues to remove an additional amount of the substrate material. Exposure of one or more additional sets of device structures through the substrate material is monitored to determine the additional amount of substrate material to remove, where the additional sets of device structures are located in the semiconductor device at a known depth different than the first set.

  • Patent number: 9793192
    Abstract: 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.

  • Patent number: 9786580
    Abstract: An apparatus comprising a substrate with multiple electronic devices. An interconnect structure formed on a first side of the substrate interconnects the electronic devices. Dummy TSVs each extend through the substrate and form an alignment mark on a second side of the substrate. Functional TSVs each extend through the substrate and electrically connect to the electronic devices. A redistribution layer (RDL) formed on the second side of the substrate interconnects ones of the dummy TSVs with ones of the functional TSVs. Step heights of the RDL over the functional TSVs are less than a predetermined value, whereas step heights of the RDL over the dummy TSVs are greater than the predetermined value.
