Special Issue: The Science of VLSI

The emergence of silicon‐based very‐large‐scale integration is one of the major technological events of our time. This development was fueled in large measure by previously obtained scientific knowledge, but the devices of modern microelectronics in turn have made possible dramatic advances in all fields of science. Physics (and the physical sciences generally) has played an important part in this story. As this special issue of PHYSICS TODAY shows, very important contributions are still being made; more are needed to support continued progress in VLSI.
