Abstract
A reaction block having a plurality of reaction chambers defined therein is provided. A bottom surface of each of the reaction chambers is configured to provide a seal for a corresponding reaction region on the substrate and around a periphery of the substrate. The reaction block includes a plurality of inlet channels and provides a gap between a top surface of the substrate and a bottom surface of the reaction block. The gap accepts a fluid from the inlet channels, wherein the reaction block includes a plurality of vacuum channels having access to the bottom surface of the reaction block to remove the fluid from the gap. A method of selectively etching a substrate for combinatorial processing is also provided.
