Abstract :
We have explored the technology design space for latchup robustness in a deep submicron process. We show using experimental data that latchup robustness can be designed into a deep submicron technology without the use of retrograde wells or trench isolation. The main parameters affecting the latchup holding voltage and the trigger current have been investigated. The application of simulations and empirical models for tailoring latchup holding voltages are also discussed.<>
