摘要
The transient-induced latchup (TLU) in CMOS ICs under electrical fast transient (EFT) test has been investigated by experimental verification. With positive and negative voltage pulses under EFT test, the TLU can be triggered on in CMOS ICs with the parasitic pnpn structure. The physical mechanism of TLU in CMOS ICs has been developed with experimental verification in time domain. All the experimental evaluations have been verified with the silicon-controlled rectifier (SCR) test structure fabricated in a 0.18-mu m CMOS technology.
