Low temperature semiconductor electronics

Abstract

The authors consider that, at any technology level, operation at liquid nitrogen temperature (LNT: 77.3 K) can directly yield a performance improvement exceeding that provided through down-scaling by a factor of two. Thus, MOS technology limits are extended by one generation through LNT operation. Because of its attractive speed, density, and power attributes, liquid-nitrogen-cooled CMOS represents a strategic technology alternative for mainframe computers, an area which has traditionally been the exclusive domain of bipolar technology. A summary of the advantages for MOS microelectronics operated at LNT is presented in a table and discussed.<>
