Abstract
Abstract In a vacuum vapor-deposition system a substrate holder is arranged stationary in the main part of a vapor-deposition chamber. Evaporation apparatuses are arranged on the floor of the vapor-deposition chamber, which is moveably connected to the main part of the vacuum-deposition chamber via a bellows and can swivel about two mutually intersecting axes or be displaced along two mutually intersecting axes with respect to the main part by means of two drive mechanisms. In this way the thermostatization of the substrate and the production of very uniform layers is facilitated.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
105 words
A vacuum-vapor-deposition system comprising a vacuum-tight vapor-deposition chamber the wall whereof includes a fixed part and a movable part, a substrate-holder adapted to hold at least one substrate to be coated arranged at said fixed part, an evaporation apparatus arranged at said movable part and having at least one heatable vapor-deposition material source, vacuum-tight connecting apparatus adapted to connect said fixed part to said movable part and means to permit a swivel motion, around two nonparallel axes, of the movable part while the fixed part remains stataionary and means coupled to said fixed part and said movable part for producing said swivel motion throughout deposition.
Claim 2
Dependent Claim
105 words
A vacuum-vapor-deposition system comprising a vacuum-tight vapor-deposition chamber the wall whereof includes a fixed part and a movable part, a substrate-holder adapted to hold at least one substrate to be coated arranged at said fixed part, an evaporation apparatus arranged at said movable part and having at least one heatable vapor-deposition material source, vacuum-tight connecting apparatus adapted to connect said fixed part to said movable part and means to permit a swivel motion, around two nonparallel axes, of the movable part while the fixed part remains stataionary and means coupled to said fixed part and said movable part for producing said swivel motion throughout deposition.
Claim 3
Dependent Claim
19 words
Vacuum vapor-deposition system in accordance with claim 1, wherein said movable part forms the floor of the evaporation chamber.
Claim 4
Dependent Claim
16 words
Vacuum vapor-deposition system in accordance with claim 1, wherein said vacuumtight connecting apparatus includes a bellows.
Claim 5
Dependent Claim
45 words
Vacuum vapor-deposition system in accordance with claim 1, wherein said fixed and movable parts are supported movably with respect to each other by means of gimbals and can be swiveled in relation to each other about two intersecting axes by means of two drive mechanisms.
Claim 6
Dependent Claim
21 words
Vacuum vapor-deposition system in accordance with claim 1, wherein said movable part is displaceably supported in relation to said fixed part.
Claim 7
Dependent Claim
29 words
Vacuum vapor-deposition system according to claim 5, incuding two drive mechanisms for independent displacement of said moveable part in relation to said fixed part in two mutually intersecting directions.
Claim 8
Dependent Claim
26 words
Vacuum vapor-deposition system in accordance with claim 1, wherein said drive mechanism includes two drive motors, the RPM of which is controllable independently of one another.
