CHIPS 2020 VOL. 2 : New Vistas in Nanoelectronics News on 8 Chip Technologies Monolithic 3D Integration Comprehensive Reliable Low Power Electronics Analog for a Digital World Interconnects Communication Developments in the Chip Market ITRS The 2014 2029 International Technology Roadmap of Semiconductors Nanolithography Power Efficient Design Super processors and Super computers Memory Hybrid 3D Integration for Wireless Multimedia Technology for the Next Generation Mobile User MEMS –Micro Electromechanical Systems Vision Chips and Cameras Digital Neural Networks Retinal Implants The Human Brain Projects Energy Harvesting and Chip Autonomy 2020 World with Chips. The release of this second volume of CHIPS 2020 coincides with the 50th anniversary of Moore’s Law a critical year marked by the end of the nanometer roadmap and by a significantly reduced annual rise in chip performance. At the same time we are witnessing a data explosion in the Internet which is consuming 40% more electrical power every year leading to fears of a major blackout of the Internet by 2020. The messages of the first CHIPS 2020 published in 2012 concerned the realization of quantum steps for improving the energy efficiency of all chip functions. With this second volume we review these messages and amplify upon the most promising directions: ultra low voltage electronics nanoscale monolithic 3D integration relevant data brain and human vision inspired processing and energy harvesting for chip autonomy. The team of authors enlarged by more world leaders in low power monolithic 3D video and Silicon brains presents new vistas in nanoelectronics promising Moore like exponential growth sustainable through to the 2030s.
