Beschreibung
Zusammenfassung:	The present invention relates to a method of driving a substrate web (950) into a reaction space of an atomic layer deposition (ALD) reactor and apparatuses therefore. The invention includes driving a substrate web into a reaction space (930) of an atomic layer deposition reactor, and exposing the reaction space to precursor pulses to deposit material on said substrate web by sequential self-saturating surface reactions. One effect of the invention is a simpler structure compared to earlier spatial roll-to-roll ALD reactors. Another effect is that the thickness of deposited material is directly determined by the speed of the web.
