Abstract:This thesis presents an SCR compact model for simulating ESD protection circuits. The aspects of the compact model that are necessary to reproduce measurement data, such as quasi-static I-V curves and transient voltage overshoot, are discussed. These aspects include conductivity modulation of the well resistances in the SCR, impact ionization at the N-well/P-well junction, and the influence of electric fields in the well region on carrier diffusion between the anode and cathode. Further, a detailed validation of the compact model is presented. A methodology for parameter extraction is also discussed.
