Nanometer CMOS characterization and compact modeling at deep-cryogenic temperatures

Edoardo Charbon, Harald Arjan Robert Homulle, Fabio Sebastiano

The characterization of nanometer CMOS transistors of different aspect ratios at deep-cryogenic temperatures (4 K and 100 mK) is presented for two standard CMOS technologies (40 nm and 160 nm). A detailed understanding of the device physics at those temper ...
