40K cryogenic rad-hard CMOS readout multiplexer fabrication process

Cryogenic signal processing and A/D conversion for the IR imaging and high energy physics experiment applications place severe demands on the silicon process involved, particularly in ionizing radiation environments. This paper describes a process specifically optimized for operation in the 40 K - 77 K temperature range in a total dose environment. Trade-offs of hardness, supply voltage and hot electron vulnerability are discussed and preliminary device- level results are shown.
