Abstract:
1. A plastic housing composition for embedding semiconductor devices in a plastic housing, the plastic housing composition comprising a multicomponent plastic material and including at least a first component distributed throughout the multicomponent plastic material as a plurality of drop-shaped and/or spherical units, each of the drop-shaped and/or spherical units being surrounded by a dimensionally stable plastic sheath so as to isolate the first component from other components in the multicomponent plastic material, and wherein the multicomponent plastic material further comprises a reactive curing system including a second component that reacts with the first component so as to cure the multicomponent plastic material upon the plastic sheath being torn open to expose the first component to the second component, the plastic sheath being dissolution-resistant with respect to each component of the multicomponent plastic material and being deformation-sensitive so as to tear open when subjected to a selected amount of mechanical deformation loading of the plastic sheath; wherein the first component surrounded by the plastic sheath includes a catalyst and a curing agent of the reactively curing system.
