Abstract

The invention relates to an apparatus (1) for coating a surface (21) of a substrate (20) which during the coating process is accommodated in a processing chamber (2) and is exposed to a stream of coating particles (23) produced by a particle source (4). A transport device (10) is provided for transport of the substrate (20) through the processing chamber (2). To avoid deposits of the coating material on sensitive components of the transport device (10), the transport device (10) is arranged in the processing chamber (2) in such a way that it is screened from the particle stream emanating from the particle source (4) by the substrate (20) to be transported. In this way, the intervals between maintenance can be extended and the operating costs of the apparatus (1) can be reduced. The invention further relates to a process for coating a surface (21) of a substrate (20) in an apparatus (1) having a processing chamber (2) for accommodating the substrate (20) during the coating process, having a particle source (4) for producing coating particles (23) and having a transport device (10) for transport of the substrate (20) in the processing chamber (2) which has a plurality of transport rollers (11a) which are fastened to a set of shafts (11b) which are mounted in bearings (11c) so as to be rotatable, are arranged behind one another in the transport direction (13) and are aligned parallel to one another, where the transport device (10) or at least one of the transport rollers (11a), one of the shafts (11b) or one of the bearings (11c) of the transport device (10) is screened from a stream of coating particles (23) emanating from the particle source (4) by the substrate (20) to be transported or by two substrates (20) to be transported in succession.

Abstract

The invention relates to a device (1) for coating a surface (21) of a substrate (20). The device comprises a processing chamber (2) with a particle source (3) for producing coating particles (19), which are also deposited on the inner wall (5) of the processing chamber (2) and on shielding devices (41) arranged therein during operation, in addition to the desired coating of the substrate surface. As the operating time increases, the layer thickness of said deposits (6) grows until the latter undergo spalling, which can lead to contamination of the substrate surfaces to be coated. In order to prevent this, shielding screens (10, 10') are arranged on the inner wall (5) of the processing chamber (2) and/or on the shielding devices (41) and prevent deposits (6, 7) which undergo spalling from passing into the interior (17) of the processing chamber (2). The shielding screens (10, 10') preferably consist of an expanded metal.
