    摘要: A compound comprises a polymeric chain with a repeat unit repeated more than 5 times. The repeat unit comprises conjugated first and second cyclic groups and a plurality of side groups each bonded to one of the cyclic groups. A side group bonded to the first cyclic group is an electron donor and a side group bonded to the second cyclic group is an electron acceptor, such that the compound is switchable between first and second electrical conductive states by application of an electric field to the compound. At least one of the side groups is selected so that the compound is soluble in an organic solvent. The compound may be used in films, memory cells, or electronic devices. A layer of the compound may be formed on a surface by dissolving the compound in an organic solvent, applying the solution to the surface, and then removing the solvent.

    摘要: A dry process to remove mold flash on integrated circuit packages (IC packages) by using pulse, short wavelength laser irradiation. The mold remnants on the surface or in holes of the lead frame can be removed by pulse laser irradiation, with the effect of thermal expansion of lead frame metals and momentum transferring from the laser beam to the mold remnants. Compared with conventional water jet or etching processes, the new technique has high productivity and does not degrade the reliability of the IC packages, due to the fact that there is no water or chemical solutions involved in the process.
