    The damaged transistor shows a low-ohmic junction between gate and drain terminals. A parametric failure only shifts the device parameters and may manifest in stress testing; sometimes, the degree of damage can lower over time. Latent ESD failure modes occur in a delayed fashion and include: Insulator damage by weakening of the insulator ...
