Thermo-Mechanical Challenges in Stacked Packaging

Abstract

The convergence of computing and communications dictates building up rather than out. As consumers demand more functionality in their hand-held devices, the need for more memory in a limited space is increasing, and integrating various functions into the same package is becoming more crucial. Over the past few years, die stacking has emerged as a powerful tool for satisfying these challenging integrated circuit (IC) packaging requirements. In this paper, a review of thermo-mechanical challenges for stacked die packaging is discussed.
