Abstract :
N-well pockets connected to the cathode of ESD diodes may be source of parasitic electrons current in P-/P++ substrates. In this paper a methodology to reduce this latch-up risk is proposed. The electrical performances of this protection technique have been characterized and the results have been validated by device simulations.
