Abstract:
A vacuum coating device for coating substrates on all sides, by moving the substrates in a particle flow, comprising:a substrate holder, a portion of which is positioned opposite the material source, wherein the substrate holder includes:a first leg having a first longitudinal axis,a second leg having a second longitudinal axis, wherein the second leg extends from the first leg at an obtuse angle,a third leg having a third longitudinal axis, wherein the third leg extends from the second leg,a planet carrier mounted at an end of the third leg opposite the second leg, anda plurality of substrate shafts extending from the planet carrier on which substrates may be mounted for coating,wherein the planet carrier and substrate shafts are positioned such that the first longitudinal axis of the first leg approximately intersects a central area where the substrates are held; anda drive mechanism for moving the substrate holder, wherein the drive mechanism:(a) rotates the substrate holder around the first longitudinal axis,(b) linearly shifts the substrate holder along the first longitudinal axis,(c) rotates the planet carrier about the third longitudinal axis, and(d) rotates the substrate shafts with respect to the planet carrier.
