Multiple waste streams, including incompatible chemicals such as concentrated acids and/or strong base effluents, are handled together without the need for limiting or interrupting the processes run by the wafer processing tools. In some embodiments, waste tanks are primed with diluents, such as water, and a predetermined percentage of diluent is maintained in the waste tanks. In some embodiments, a diluent is flowed into the waste tanks concurrently with the waste pumping to generate a rinsing action for the waste tanks. Methods of the present disclosure accommodate both gravity type and vacuum type waste tanks.

Effluent management, waste dilution, effluent pre-dilution, acid waste handling

A cleaning assembly is provided. The cleaning assembly includes a plate having a front surface and a back surface and a manifold affixed to an edge of the plate. The manifold has a plurality of outlets extending therefrom. The plate further includes a plurality of cups extending through the plate. The plurality of cups have an upper body with an outlet extending from the back surface and the plurality of cups have a sealing portion coupled to the upper body and extending from the front surface of the plate. Each outlet of the upper body is coupled to one of the corresponding plurality of outlets of the manifold. The plate also includes a plurality of alignment pins extending from the front surface of the plate. The plurality of alignment pins are configured to support an edge of a substrate, wherein one of the plurality of alignment pins is slidably mounted to the plate. A plurality of guide pins extends the same distance from the back surface.

Ex-situ cleaning assembly

Provided are methods and systems for dispensing different chemicals used for high productivity combinatorial processing. A dispense panel may include multiple inlet lines for supplying different chemicals. Each inlet line is connected to its own three-way valve that either allows the supplied chemical to flow from the inlet line towards a dispense valve connected to a dispense manifold (during dispensing of the supplied chemical) or allows another chemical to flow from the dispense valve to a waste manifold (during priming of the dispense manifold with this other chemical). Specifically, during priming a chemical supplied from its inlet line and is passed through a corresponding three-way valve and is directed to its dispense valve and then into the dispense manifold. Other dispense valves and three-way valves of the dispense panel allow this chemical to flow out of the dispense manifold, thereby priming remaining parts of the panel.

Methods and systems for dispensing different liquids for high productivity combinatorial processing

Overlapping combinatorial processing can offer more processed regions, better particle performance and simpler process equipment. In overlapping combinatorial processing, one or more regions are processed in series with some degrees of overlapping between regions. In some embodiments, overlapping combinatorial processing can be used in conjunction with non-overlapping combinatorial processing and non-combinatorial processing to develop and investigate materials and processes for device processing and manufacturing.

Full wafer processing by multiple passes through a combinatorial reactor

A cleaning chamber is provided. The cleaning chamber includes a base portion housing a chuck and a lid affixed to the base portion. A support assembly is linked to the lid and the support assembly includes a top plate spaced apart from a bottom plate, the top plate has a plurality of openings defined therethrough and the bottom plate has a plurality of openings defined therethrough. The cleaning chamber includes a plurality of cups extending through corresponding pairs of the plurality of openings of the top plate and the bottom plate. The plurality of cups is configured to seal against a surface of a substrate, wherein each cup of the plurality of cups is independently supported by the bottom plate.
