  • Patent number: 7879691
    Abstract: Exemplary embodiments provide methods and systems for assembling electronic devices, such as integrated circuit (IC) chips, using a release member having a phase change material. Specifically, IC elements/components can be selectively received, stored, inspected, repaired, and/or released in a scalable manner during the assembly of IC chips by inducing phase change of the phase change material. The release member can be flexible or rigid. In some embodiments, the release member can be used for a low cost placement of the IC elements in combination with an SOI (silicon on insulator) wafer and/or an intermediate transfer member. In other embodiments, the release member can be used for a low cost placement of the IC elements in combination with a release wafer.
