Abstract

A device for the treatment of substrates has a container having walls and being filled with a treatment fluid. At least one substrate carrier is mounted in the container so as to move the substrates vertically in a reciprocating manner without a substrate support. Substrate side walls are provided between the substrates and the container walls. These substrate side walls extend parallel to the substrates and are vertically movable in a reciprocating manner with the substrates.
