Resiliency challenges in sub-10nm technologies

Improvements in chip manufacturing technology, driven by high degree of integration due to small device sizes and additional complex functionalities enabled by heterogeneous integration, have propelled an astonishing growth of computing systems. While the pervasiveness of these systems enables emerging application domains, however, this trend is facing serious challenges, both at device and system levels. As the minimum feature size continues to shrink, a host of vulnerabilities influence the robustness, reliability, and resiliency of embedded and critical systems. Some of these factors are caused by the stochastic nature of the nanoscale manufacturing process, while other factors appear because of high frequencies and nanoscale features. This paper overviews the vision by some of the key industrial players regarding the emerging resiliency challenges faced at the extreme nanoscale technologies.
