Mixed mode TCAD simulations are used to show the effects of guard bands and high density well contacts in maintaining the well potential after a single event strike and thus reduce the width of long transients in a 130-nm CMOS process. Experimental verification of the effectiveness in mitigating long transients was achieved by measuring the distribution of SET pulse widths produced by heavy ions for...
The distributions of SET pulse-widths produced by heavy ions in 130-nm and 90-nm CMOS technologies are measured experimentally using an autonomous pulse characterization technique. The event cross section is the highest for SET pulses between 400 ps to 700 ps in the 130-nm process, while it is dominated by SET pulses in the range of 500 ps to 900 ps in the 90-nm process. The increasing probability...
This work provides a comprehensive summary of radiation-induced soft error rate (SER) scaling trends of key CMOS bulk devices. Specifically we analyzed the SER per bit scaling trends of SRAMs, sequentials and static combinational logic. Our results show that for SRAMs the single-bit soft error rate continues to decrease whereas the multi-bit SER increases dramatically. While the total soft error rate...
