A method and device are provided for cleaning of an optical position measurement system in a coating installation. The optical position measurement system includes a cantilever, and a sensor head having a radiation inlet and/or outlet for the reception and/or emission of an optical signal, at a free end of the cantilever. For tempering of the sensor head, a local thermoregulation is applied using a heater and/or cooling device for heating and/or cooling of the sensor head depending on thermal conductivity of material of at least the sensor head and depending on secondary heat in the coating installation.

Conveyor devices, in particular for use in substrate treatment devices, and configurations of substrate treatment devices, in particular horizontal coating installations for the mass coating of plate-like substrates during the production of solar cells are provided. The conveyor device comprises a multiplicity of conveyor rollers, each mounted rotatably at both ends thereof. During operation of the conveyor device, at least one conveyor roller is displaceable axially, i.e. parallel to the axis of rotation thereof.

A method is provided for producing a processing atmosphere for coating substrates, with this method primarily being used in CVD-processes for precipitating an individual layer or a system of individual layers under defined processing atmospheres, in which processing gas is supplied to a coating chamber in a defined manner and exhausted. Via the method and related devices, a variable processing atmosphere is adjustable inside the coating chamber in a flexible, reliable and homogenous manner, and requiring a reduced maintenance and energy expense, even when the substrate is heated. The processing gas is created by at least one gas channel extending perpendicular in reference to the substrate by way of supplying gas flow or exhausting, with a lateral extension being equivalent to the width of the substrate.

A substrate-treatment installation includes a vacuum chamber, a substrate treatment device within the vacuum chamber, a substrate transport device within the vacuum chamber for guiding a substrate along a longitudinal direction in a substrate transport plane past the substrate treatment device, and a device for controlling substrate temperature. The substrate temperature controlling device includes a heat-absorbing cooler on one side of the substrate transport plane and an insulation member selectively displaceable between at least two different positions to vary extent of thermal shielding of the heat-absorbing cooler relative to the substrate transport plane by the insulation member.
摘要:
A device for controlling the temperature of substrates in a substrate-treatment system, in which a substrate can be guided in the longitudinal extension of the substrate-treatment system in a substrate transport plane within a vacuum chamber past a treatment device, solves the problem of dynamically shaping a dynamic change of the thermal insulation to control the heat transfer in the substrate and thereby, reduce, in particular, thermal inertias by providing a heat-absorbing cooler side of the substrate transport plane. The heat-absorbing cooler can be shielded, at least partially from the substrate transport plane, using an insulation member.

A heater panel of a radiant heater includes a heating spiral provided on a panel element and mechanically connected to the panel element with a portion of a spiral turn. With the object of providing a heater panel with a stable arrangement of the heating spiral on the panel element by which a high power density is achievable, each spiral turn is detachably connected to the panel element by three spaced-apart contact spots. Two of said contact spots are located on the outer circumference of the spiral turn in such a distance to each other that the radii originating at them define an angle of less than 180°, and the third contact spot is located on the inner circumference of the spiral turn within the portion of the spiral turn facing the panel element and confined by the two outer contacts.
摘要:
The transporting device according to the invention, in particular for transporting sheet-like substrates through a coating installation, comprises transporting rollers which are rotatably mounted on both sides and horizontally arranged transversely in relation to the transporting direction, the uppermost surface lines of the transporting rollers defining the transporting plane, and is characterized in that the end parts of the transporting rollers have a smaller diameter than the middle part of the transporting rollers and in that baffles which are mounted displaceably in the axial direction of the transporting rollers between a first position and a second position are arranged between the end parts of the transporting rollers and the transporting plane. The fact that the baffles are mounted in an axially displaceable manner has the effect of considerably extending the cleaning intervals of the transporting device. At first the baffles are arranged in a first position, in which the end of the baffle lies underneath the substrate and, in the horizontal direction, as close as possible to the middle of the transporting roller Vapor-depositing material that gets beyond the edge of the substrate hits the baffle. During operation of the transporting device, the baffles are continuously displaced from the middle part to the ends of the transporting rollers. As a result, the increase in thickness of the layer produced on the baffles is limited, since the vapor keeps hitting new portions of the baffle.
