(under subclass 788) Subject matter wherein the encapsulant includes polyimide i.e., a polymeric compound resulting from replacement of both atoms of hydrogen in an organic amine by organic univalent acid radicals or by an organic divalent acid radical.
(1) Note. Polyimides are copolymers (polymers formed from at least two different starting organic materials) which have a linkage, as illustrated below, between the starting materials, wherein R is typically hydrogen and Q1 and Q2 are the organic residues of the starting monomers.
