Abstract:
1. A method for wetting a substrate surface of substrates with a liquid process medium comprising the following steps: transporting a plurality of discrete substrates with a plurality of transport means in a transport plane, the transport plane being substantially horizontal; wetting a downwardly directed underside surface of each said substrate positioned at least substantially in said transport plane with said process medium, wherein said process medium is applied to said underside substrate surfaces by said transport means; and suctioning off a mist, vapor, or gas form of said liquid process medium arising from said liquid process medium, the suctioning taking place with a plurality of suction means located in a vicinity of a tank filled with said liquid process means, said suction means arranged vertically below said transport plane in order to prevent a deposition of said process medium on surfaces of each said substrate other than said downwardly directed underside substrate surface located in said transport plane, said suction means being interposed between said plurality of transport means.
