Year after year, the limits of MOS technologies are becoming more and more tightening. Due to the nanoscale effects of transistors and interconnections, new designs require a lot of effort to keep the performance-increasing trend: thermal and electrical uncertainties have to be counteracted at high design-abstraction levels. Moreover, only a few factories in the world are able to manufacture the latest-technology chips. This is why a key factor of a new technology could be, among the other factors, an easier and faster manufacturing. This could also promote a manufacturing cost reduction, allowing more factories to build state-of-the-art chips. In this framework, molecular electronics plays a central role.
