The influence of high resistivity substrates on CMOS latchup robustness

This paper demonstrates latchup results in a 50 Omega-cm substrate wafer in a 0.13-mum technology. Latchup evaluation will evaluate and compare a 10 Omega-cm and a 50 Omega-cm substrate wafer on the NPN bipolar current gain, beta<sub>npn</sub>, PNP bipolar current gain, beta<sub>pnp,</sub>, the bipolar current gain product, beta<sub>pnp</sub>beta<sub>npn</sub>, undershoot, and overshoot phenomena.
