Abstract
Disclosed herein is means adapted for use in combination with magnetically-enhanced sputtering devices whereby said devices are rendered more useful for sputter-coating substrates susceptible to heat-induced deterioration. Said means comprises a screen-like mesh or grid member disposed intermediate the target of said device and the substrate to be coated, and in such a position that said means is also disposed across the magnetic field formed by said device. Said screen-like mesh or grid member is formed of material which is magnetizable in response to the disposition thereof across said magnetic field. Said screen-like mesh or grid member has the desirable effect of suppressing the expansion of heated plasma whereby said plasma is confined to a region proximate said target and generally away from said substrate. Also disclosed is improved anodic means for collecting fast electrons emitted from said target.
