摘要:
A transport device for a vacuum processing system, a drive unit for high temperature processes in vacuum processing systems, and a vacuum processing system employ a drive unit which operates without the polygonal effect, can be connected endlessly, is suitable for high temperatures, is insensitive to radiation heat, does not generate degassing and does not need a lubricant. The drive unit includes a traction element, guided around at least two deflecting rollers. The traction element is a continuous metal strip.

A surface heating device for a substrate treatment device with increased power density and improved homogeneity of heat radiation includes a jacket tube heater with straight tube sections and bent tube sections in which straight tube sections are arranged parallel to each other in a main plane and straight tube sections are connected to each other by bent tube sections, so that at least part of the bent tube sections are aligned sloped relative to the main plane.
摘要:
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.

摘要:
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.
摘要:
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.

An apparatus and method for heat absorption in vacuum coating installations includes an absorber having a line system to supply a coolant. The line system is enclosed by a jacket tight relative to the vacuum chamber, flow spaces are arranged between the line system and the jacket, which are connected to a source of heat exchanger medium so that the line system is flowed around by a heat exchanger medium sealed relative to the vacuum chamber.
