Abstract

Silicone gels are becoming some of the most accepted protective coatings for VLSI integrated circuits due to their excellent electrical, thermal, and soft gel-like nature and properties, as well as their ultra-purity and ability to protect IC devices against severe environments. Recent studies indicate that proper IC Chip surface protection with high performance silicone gels in low-cost, non-hermetic plastic packaging might well replace the conventional hermetic ceramic packaging. This paper describes the use of the soft silicone gels and coatings in IC devices. It also describes the correlation between the material cure temperature and cure time versus their adhesion and electrical reliability during 85°C, 85% RH and bias accelerating testing.
