Description

N and p channel MOSFETs from four bulk CMOS technologies and two CMOS/SIMOX technologies were characterized for total dose response up to 1 Mrad (SiO2) at temperatures from 10K to 120K. The peak transconductance in the linear region increased in n channel devices and decreased in p channel devices for devices with lightly doped drain (LDD) implants. These changes were much larger as the temperature was decreased and were as much as a factor of 50 in p MOSFETs at 10K. The one technology without LDD showed only a minor change in gm with dose even at 10K. The changes in transconductance are most likely a result of hole trapping in the spacer oxide affecting the series resistance
