Promise of form-factor reduction and hybrid process integration by three-dimensional (3D)-stacked integrated circuits (3DICs) has spurred interest in both academia and industry. In this study, through-silicon-via (TSV)-based 3D integration is discussed from a microprocessor centric view. The authors present the challenges faced by technology scaling and provide 3D integration as a possible solution. The applications for 3DICs are discussed with details of a few prototypes. The issues and challenges associated with 3D integration technologies are also addressed. TSV-based 3D integration technology will allow integration of diverse functionality to realise energy-efficient and affordable compact systems that will continue to deliver higher performance.
