Abstract:
1. A method for processing a substrate using a proximity system defined by one or more proximity heads, comprising: applying a first fluid meniscus to a surface of the substrate to apply a chemical precursor to the surface of the substrate, through a first proximity head; applying a second fluid meniscus to the surface of the substrate to leave an atomic layer of the chemical precursor on the surface of the substrate, through a second proximity head; and applying a third fluid meniscus to the surface of the substrate to apply a chemical reactant configured to react with the atomic layer of the chemical precursor to generate a layer of a material, through a third proximity head; wherein the first, second and third proximity heads are arranged to apply the first fluid meniscus, the second fluid meniscus and the third fluid meniscus one after the other, so that a same location of the surface of the substrate is processed.
