  • Publication number: 20060252354
    Abstract: Electronic device support and processing methods are described. One embodiment includes a method of processing an electronic device including solder bumps extending therefrom. The method includes providing at least one fluid selected from the group consisting of electrorheological fluids and magnorheological fluids on a support structure. The solder bumps extending from the electronic device are positioned in the fluid. The fluid is activated by applying a field selected from the group consisting of an electric field and a magnetic field to the fluid. The activated fluid mechanically holds the electronic device in place. A surface of the electronic device is polished while the electronic device is held in place by the activated fluid. The fluid is deactivated by removing the applied field from the fluid, and the electronic device is separated from the deactivated fluid. Other embodiments are described and claimed.

  • Publication number: 20060046433
    Abstract: Wafer thinning may be accomplished by grinding while the wafer is held in the fixture. The fixture may have a series of protrusions that form an interference fit with surface features extending outwardly from the non-thinned surface of the wafer to be thinned. In some embodiments, a releasable adhesive may be utilized to augment the interference effect. Also, in some embodiments, openings in a shape memory material may be utilized that, upon heating, more firmly engage the bumps on the wafer to be thinned.
