(a) View of a partial cross-section of an apparatus suitable for carrying out the teachings of the invention; (b) Enlarged view of the substrate transport system utilized in the apparatus of (a). In a vacuum chamber “6”, a high voltage is applied by the generator “36” to an electrical wire “44” connected to a flexible contact strip “88” in contact with the supply spool “52” while the ground is imposed via “42” and “90” to the other supply spool “54”. Two flexible and metal substrates “66”, “68” are unwound from supply spools “52”, “54” and pass along convergent paths to guide rollers “58”, “60”.
