Abstract:
1. An ion beam source capable of emitting an ion beam toward a substrate, the ion beam source comprising: an anode and a cathode, wherein an aperture is defined in at least one of the anode and cathode; wherein an electric gap is defined between the anode and the cathode; at least one magnet for generating a magnetic field proximate the aperture, wherein an ion beam is to be emitted toward a substrate from an area in and/or proximate the aperture; and means for introducing both a depositing gas and a maintenance gas that is different than the depositing gas into the ion beam source via a depositing chamber in which the substrate is to be located; wherein the ion beam source is a cold cathode type ion source and there are no means to introduce gas from the anode side.
