Abstract
A coating apparatus (100) for batch coating of substrates is presented. In the batch coater layers of a stack can be deposited by means of physical vapor deposition, by means of chemical vapor deposition or by a mixture of both processes. When compared to previous apparatus, the mixed mode process is particularly stable. This is achieved by using a rotatable magnetron (112) rather than the prior-art planar magnetrons. The apparatus is further equipped with a rotatable shutter that allows for concurrent or alternating process steps.
