Device challenges and opportunities

Abstract

CMOS technology is facing exciting opportunities and formidable challenges. They include mobility scaling to overcome the speed/power barrier, new gate-stack materials and/or new device structures; to overcome the gate-length/leakage barrier; nonvolatile memory and universal memory to enlarge the market, and containment of costs. CMOS has much more to give in the next two decades, yet it is not too early, especially in universities, to start searching for not-CMOS-like circuit/system architectures that may require non-existing new devices but offer the promise of dramatic reduction in power and cost.
