  • Patent number: 8999498
    Abstract: Methods and apparatuses for releasably attaching support members to microfeature workpieces to support members are disclosed herein. In one embodiment, for example, a method for processing a microfeature workpiece including a plurality of microelectronic dies comprises forming discrete blocks of material at a first side of a support member. The blocks are arranged on the support member in a predetermined pattern. The method also includes depositing an adhesive material into gaps between the individual blocks of material and placing a first side of the workpiece in contact with the adhesive material and/or the blocks. The method further includes cutting through a second side of the workpiece to singulate the dies and to expose at least a portion of the adhesive material in the gaps. The method then includes removing at least approximately all the adhesive material from the support member and/or the workpiece with a solvent.

  • Patent number: 8669179
    Abstract: A through-wafer interconnect for imager, memory and other integrated circuit applications is disclosed, thereby eliminating the need for wire bonding, making devices incorporating such interconnects stackable and enabling wafer level packaging for imager devices. Further, a smaller and more reliable die package is achieved and circuit parasitics (e.g., L and R) are reduced due to the reduced signal path lengths.
