    Abstract: A package for microelectronic circuits includes a frame made of a high molecular weight plastic material, such as a liquid crystal polymer (LCP), attached to a flange, or leadframe. The plastic material is injection molded to the flange. Initial polymerization of the plastic material can occur in a liquid state and results in an intermediate material having an initial melting temperature. After the frame is injection molded, the frame is heated and undergoes further (secondary) polymerization, thereby lengthening polymer chains in the plastic material. These longer polymer chains have higher molecular weight, and the resulting final material has a higher melting temperature, than the intermediate material. The resulting ultra-high molecular weight polymer can withstand high temperatures, such as those encountered during soldering. Thus, after the further (secondary) polymerization, a die can be soldered to the flange, without damaging the plastic frame.

    Abstract: A polymer including a self-immolative polymer segment and a thermally-activated trigger moiety is described. The self-immolative polymer segment includes a head end, a tail end, and a plurality of repeating units. The trigger moiety includes a cycloaddition adduct that is covalently coupled to the head end of the self-immolative polymer segment. When the polymer is exposed to an activation temperature, the cycloaddition adduct undergoes retro-cycloaddition to release the self-immolative polymer segment. The self-immolative polymer segment then decomposes to sequentially release repeating units in a head-to-tail direction.
