Beschreibung
Zusammenfassung:	A substrate processing apparatus including a reaction chamber with an inlet opening, an in-feed line to provide a reactive chemical into the reaction chamber via the inlet opening, incoming gas flow control means in the in-feed line, the in-feed line extending from the flow control means to the reaction chamber, the in-feed line in this portion between the flow control means and the reaction chamber having the form of an inlet pipe with a gas-permeable wall, the inlet pipe with the gas-permeable wall extending towards the inlet opening through a volume at least partly surrounding the inlet pipe, and the apparatus (100, 800) being configured to provide fluid to surround and enter the inlet pipe in said portion.
