An atmospheric pressure plasma etching reactor has a table holding a wafer to be processed and which moves the wafer to be processed under at least one electrode that is mounted in close proximity to the table and defines an entry of a gas mixture. With a radio-frequency voltage connected between the table and the at least one electrode, a plasma is created between the at least one electrode and the wafer to be processed processing the wafer to be processed as it is moved under the at least one electrode by the table.
