Abstract	The success in consumer electronics in the 1990's will be focused on low-cost and high performance electronics. Recent advances in polymeric materials (plastics) and integrated circuit (IC) encapsulants have made high-reliability very-large-scale integration (VLSI) plastic packaging a reality. High-performance polymeric materials possess excellent electrical and physical properties for IC protection. With their intrinsic low modulus and soft gel-like nature, silicone gels have become very effective encapsulants for larger, high input/output (I/O) (in excess of 10 000), wire-bonded and flip-chip VLSI chips. Furthermore, the recently developed silica-filled epoxies underfills, with the well controlled thermal coefficient of expansion (TCE), have enhanced the flip-chip and chip-on-board, direct chip attach (DCA) encapsulations. Recent studies indicate that adequate IC chip surface protection with high-performance silicone gels and epoxies plastic packages could replace conventional ceramic hermetic packages. This paper will review the IC technological trends, and IC encapsulation materials and processes. Special focus will be placed on the high-performance silicone and epoxy underfills, their chemistries and use as VLSI device encapsulants for single and multichip module applications.
