A method produces semiconductor wafers in a chamber of a deposition reactor of a plant. The method includes: repeatedly depositing an epitaxial layer on a substrate wafer in the chamber, producing semiconductor wafers, and at the same time: conditioning a replacement chamber outside the plant by purging the replacement chamber with a purge gas; interrupting the deposition of the epitaxial layer; replacing the chamber with the replacement chamber, after the conditioning, the replacement chamber being sealed and transported in a closed state to the plant or after the conditioning, the replacement chamber is transported to the plant and in this process purge gas is passed through the replacement chamber; and continuing the deposition of the epitaxial layer in the replacement chamber, producing a second number of semiconductor wafers.
