Abstract: In this paper, the ferroelectric polarization effect of ZrO 2 capping layer on HfO 2 MFM capacitor was investigated. Based on crystallinity analysis, the phase transformation from monoclinic to orthorhombic phase in HfO 2 film can be induced by a thin ZrO 2 capping layer. capping layer.
Capacitors usually determine the overall lifetime of power converters since they are mainly responsible for breakdowns. Their failure results from the deterioration of their dielectric, the production of gases, and, eventually, their explosion. This process leads to an increase in the capacitor equivalent series resistance (ESR) and a decrease …
