Claim 12:
13. A substrate holding and locking method for chemical and/or electrolytic surface treatment of a substrate in a process fluid, comprising the following steps:
arranging a substrate between a first element and a second element, and
locking the first element and the second element with each other by means of a magnetic locking unit, and
reducing an interior pressure inside the substrate holding and locking system below atmospheric pressure by means of a pump of a reduced pressure holding unit,
wherein the magnetic locking unit comprises a magnet control and at least a magnet,
wherein the magnet is a permanent magnet and is arranged at one of the first element and the second element,
wherein the magnet control is configured to control a magnetic force between the first element and the second element, and
to eliminate the magnetic force of the permanent magnet to allow a release of the second element relative to the first element.
