Abstract: Advances in the theory of semiconductors in the 1930s coupled with the purification of germanium and silicon crystals in the 1940s enabled the point-contact junction transistor demonstration in 1947 and initiated the era of semiconductor electronics. Gordon Moore postulated that the number of components in an integrated circuit would double every two years with associated reduction in cost per transistor. Transistor density doubling through “scaling” with each new process node continues today, albeit at a slower pace. Scaling resulted in exponential gain in performance and energy efficiency of integrated circuits that has transformed computing from main-frames to personal computers, from mobile computing to cloud computing, from general purpose computing to domain specific computing. Innovations in new materials, transistor structures, cryogenic operation and design-technology co-optimization will continue transistor density scaling. Monolithic 3D integration and polylithic chiplet assembly will result in tight co-integration of memory on top of logic, whereas backside power delivery and power conversion technologies will exploit silicon asset beneath the logic transistor later. Together, these technologies will lead to continued advances in performance, energy efficiency and density of transistors in future microsystems.
