Abstract

A method and structure for improving high voltage breakdown reliability of a microelectronic device, e.g., a galvanic digital isolator, involves providing an abatement structure around metal plate corners of a high voltage isolation capacitor to ameliorate the effects of an electric field formed thereat during operation of the device due to dielectric discontinuity.
