1. A method for plating a recess in a substrate (10), comprising the following steps:
providing a substrate (10) with a substrate surface (11) comprising at least one recess,
applying a replacement gas (30) to the recess to replace an amount of ambient gas (20) in the recess to at least partially clear the recess from the ambient gas (20), wherein the replacement gas (30) is continuously circulated without any application of sub-atmospheric pressure or vacuum,
applying a processing fluid (40) to the recess, wherein the replacement gas (30) dissolves in the processing fluid (40) to at least partially clear the recess from the replacement gas (30), and
plating the recess in the substrate (10).
