Abstract

The present invention relates to a boundary element for a process tank. The process tank is suitable for holding a chemical process solution. The boundary element is provided with at least one slot for passing wafers through the boundary element. The inner wall of the slot is structured such that process solution flowing out of the process tank undergoes a change in momentum such that the volumetric flow flowing out is decreased. As a result of the boundary element of the invention, the outflow of process solution out of the process tank can be reduced. Since less process solution passes out of the process tank, process costs can be saved since either less process solution is required or less process solution needs to be circulated. The invention can be used, inter alia, in the production of solar cells, or of printed circuit boards, for example printed circuit boards for the electrical industry.
