Title
MIM capacitance variation under electrical stress
Abstract
Due to strong requirement in term of capacitance voltage linearity, MIM capacitance stability during the whole operating lifetime of the product appears to be a key issue to warrant the reliability of this device. Using a constant current stress, two effects can be noticed on the evolution of the stressed C–V characteristics: a voltage shift to negative bias and a significant increase of the capacitance. Both phenomena have been demonstrated to be strongly correlated and to have the same origin: the trapped charges in oxide, which can generate new dipoles in the dielectric and, as a result, modulate the dielectric permittivity.
