Sofics has supported several companies in the past on radiation tolerant applications and other harsh environments. We worked both on prevention of Single Event Latch-up and on prevention of degradation due to Total dose irradiation.
Examples in different processes
Sofics ESD technology and knowledge used for rad-hard applications. We have provided our Analog IOs and ESD clamps to CERN for use in their experiments. They have sourced technology from us in 130nm, 65nm and 28nm. We have delivered ESD clamps to a large US based FPGA maker that sources its solutions to aerospace applications.
They ran tests (@ Berkeley) on our 65nm solutions and did not see failures up to 120 LET. We have supported a few companies in their ASIC design for use in satellites. We have supported companies developing radiation hard products or libraries
