Abstract:
A semiconductor package in which a silicon die is adhered to a substrate with a die attach adhesive formulation comprising(a) a resin having a segment containing silane and a segment containing at least one carbon to carbon double bond in which the resin has the structure â€ƒin which (i) Q is an oligomeric or polymeric group containing at least one carbon to carbon double bond, (ii) n is simultaneously for each position 0, 1, or 2; (iii) R1 is a methyl or ethyl group; (iv) R2 is a vinyl group, an aromatic group, or a linear or branched alkyl group of 1 to 4 carbon atoms; (v) A is a hydrocarbyl group or an aromatic group; (vi) L is a linking group resulting from the reaction of a functional group, excluding epoxy, on the precursor for the segment containing silane and a functional group, excluding epoxy, on the precursor for the segment containing the at least one carbon to carbon double bond; (b) a curing agent; (c) optionally, a filler.
