  • Abstract
    Unexpected device interactions between ESD diodes and NMOS clamps in isolated P-well (triple well) have been observed. This can lead to an SCR-like I-V behavior in TLP measurements and poses a latch-up risk. The cause of this interaction is being analyzed using equivalent circuits with parasitic devices and by TCAD simulations.
