At large separations, the behaviour of electrodes has been widely studied and is reasonably well understood. However, some fundamental problems have not been properly addressed such as maximum safe operating voltages and critical dimensions required at small separations between different types of materials. A systematic study of electrical breakdown at sub-millimetre separations using materials commonly used in the fabrication of microdevices has been undertaken. Specimens for examination at electrode separations from 500 nm to 25 µm have been made with different electrode configurations, such as flat to flat, flat to point and point to point. All the tests were made in air and at differing pressures.
