Three-dimensional (3D) integration of ICs provides unique opportunities to improve bandwidth, latency, and power dissipation bottlenecks of interconnects (both on- and off-chip). However, while 3D IC integration improves signal interconnection, it also presents new challenges, especially in power delivery and cooling (“thermal interconnects”). The focus of this paper is on some of the key challenges and promising technologies to address power delivery, cooling, and signaling in a 3D stack of logic ICs.
