For the evacuation of a low-vacuum chamber (4) and of a high-vacuum chamber (5), two pump trains (6, 7) are provided, each consisting of a vacuum pump unit (8, 9) and a forepump unit (10, 11). The forepump unit (11) of the pump train (7) of the high-vacuum chamber (5) can draw selectively from the vacuum pump unit (9) of the high-vacuum chamber (5) or from a high-vacuum pump unit (12) connected likewise to the high-vacuum chamber (5). The vacuum pump unit (9) can aspirate either from the highvacuum chamber (5) or from the low-vacuum chamber (4) and discharge to the forepump unit (10) of pump train (6) or to the forepump unit (11) of pump train (7).

The invention relates to a flooding chamber for coating installations, with which shorter flooding times, and therewith shorter clock cycles, can be attained. Two flooding means are therein utilized, between which a substrate is disposed symmetrically. The flooding means direct a gas jet directly onto the substrate. Hereby the substrate is fixed between the flooding means.

A lock chamber for a substrate processing system is provided which includes at least a first conduit adapted to provide an inner portion of the lock chamber in fluid communication with atmospheric pressure or overpressure. Additionally, the lock chamber includes at least a first control valve for controlling a flow rate of the fluid communication of the inner portion of the chamber with the atmospheric pressure or the overpressure, wherein the control valve is adapted to continuously control the flow rate. Furthermore, an according method, a computer program and a computer readable medium adapted for performing the method is provided.
摘要:
The invention relates to a substrate carrier comprising two vertical plates and two horizontal plates. In order for the substrate during its transport through a sputter unit to be coated uniformly in its margin regions, a lever arrangement is provided between the two vertical plates. The lever arrangement comprises at least one horizontal web which under the effect of heat expands to a lesser degree than the horizontal plates.
摘要:
An electrode arrangement for the plasma-aided coating of a substrate (3) with a layer of material comprising at least one first and a second material component and for the production of a plasma discharge, more especially an arc discharge (35), having an anode arrangement (5), which provides the first material component at an anode material surface (13) for evaporation, and a cathode arrangement (7), which provides the second material component at a cathode material surface (25). The electrode arrangement is characterized in that the cathode material surface (25) is constituted by an evaporation-active part (27) supporting the plasma discharge (35) and an evaporation-inactive part (41) not supporting the plasma discharge. Preferably, a motion-producing means (49) is provided for moving the evaporation-inactive part (41) over the cathode material surface (25) in order to reduce deposit of material due to he first material component on the cathode material surface (25).
摘要:
The invention relates to a method and device for the determination of the gas permeability of a container, for example, a PET bottle. Said container is enclosed by a sheath, which hermetically seals the container from the environment. The intermediate space, between the container and the sheath, has only a very small volume in comparison to the volume of the container. The determination of the gas permeability is begun by bringing said intermediate space to, for example, atmospheric pressure, whilst the container is filled with a test gas by means of a special feed, until the container is at an overpressure relative to the intermediate space. The pressure in the intermediate space increases by means of the resulting diffusion of the test gas through the wall of the container into said intermediate space. The increase in pressure per unit time is a measure of the permeability of the container.
