An apparatus for coating a substrate using physical vapor deposition, including a vacuum chamber wherein a coil is placed for keeping an amount of conductive material in levitation and for heating and evaporating that material, using a varying electric current in the coil. Isolating member are placed in the coil to isolate the coil from the levitated material. The isolating member is part of a container made of non-conductive material. The container has one or more openings for guiding evaporated conductive material to the substrate to be coated. A method for coating a substrate using physical vapor deposition is also presented.
