Die attach adhesive compositions

摘要

A novel thermally reworkable die attach adhesive composition for attaching a semiconductor device to a substrate is provided. The composition comprises (a) a thermally reworkable crosslinked resin produced by reacting at least one dienophile having a functionality greater than one and at least one 2,5-dialkyl substituted furan-containing polymer, and (b) at least one thermally and/or electrically conductive material present in an effective amount up to about 90% by weight of the die attach composition to provide a conducting medium.
