US Patent 7772042 Solvent softening to allow die placement

Exemplary embodiments provide methods and systems for assembling electronic devices, such as integrated circuit (IC) chips, by selectively and seating IC elements onto/into a receiving substrate, such as a chip substrate. Specifically, the assembly of IC chips can include embedding IC elements onto the receiving substrate upon softening the receiving substrate. Such softening can be performed by using a softening agent and/or an activatable thermal barrier material. In an exemplary embodiment, pockets can be formed in the receiving substrate using the activatable thermal barrier material for the IC assembly.
