Drastic Change in Non-Linear Resistive Materials I(V) Characteristics
Non-linear Resistive Materials are thought to be able to solve aging issues due to intense electric field near triple junction in DBC/AMB substrate of power module. In present study, non-linear I(V) behavior of epoxy/ZnO microvaristor is characterized. Large change in the I(V) characteristic is observed during successive measurements, meaning that material degradation occurred. Optical microscopy of the material surface gave an insight of the phenomenon leading those modifications, an hypothesis on the degradation mechanism is proposed.
