Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus which efficiently supplies and removes fluids to and from wafer surfaces while reducing contamination and decreasing wafer cleaning cost. SOLUTION: While a fluid meniscus treats a top surface 108a, a wafer 108 is rotated, or may be held still, and a proximity head 106 is moved. The proximity head 106 includes source inlets 1302 and 1306 and a source outlet 1304. Isopropyl alcohol vapor 1310 in nitrogen gas is supplied to the wafer surface through the source inlet 1302, and a vacuum 1312 acts on the wafer surface through the source outlet 1304, and a treatment fluid 1314 is supplied to the wafer surface through the source inlet 1306.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of cleaning a substrate using a non-newtonian fluid. SOLUTION: A non-newtonian fluid flowing between a surface of a supply unit 704 and a surface of a substrate 702 has a high yield point compared with shearing stress applied to the non-newtonian fluid over a gap 706. Therefore, most of flow of the fluid becomes plug flow. In other words, part of flow to be the plug flow substantially extends between the surface of the supply unit 704 and the surface of the substrate 702. Therefore, a flow rate profile of the flow is substantially uniform. In an embodiment, the term "substantially" implies that the plug flow extends about 80% to 100% between the surfaces.

Abstract:
A method for processing a substrate is provided which includes generating a fluid meniscus to process the substrate and applying the fluid meniscus to a surface of the substrate. The method further includes reducing evaporation of fluids from a surface in the substrate processing environment.

Abstract:
An apparatus and method are disclosed in which a semiconductor substrate having a surface containing contaminants is cleaned or otherwise subjected to chemical treatment using a foam. The semiconductor wafer is supported either on a stiff support (or a layer of foam) and foam is provided on the opposite surface of the semiconductor wafer while the semiconductor wafer is supported. The foam contacting the semiconductor wafer is pressurized using a form to produce a jammed foam. Relative movement between the form and the semiconductor wafer. such as oscillation parallel and/or perpendicular to the top surface of the semiconductor wafer. is then induced while the jammed foam is in contact with the semiconductor wafer to remove the undesired contaminants and/or otherwise chemically treat the surface of the semiconductor wafer using the foam.
Abstract:
METHOD AND APPARATUS FOR CLEANING A SUBSTRATE USING NON-NEWTONIAN FLUIDS A method for cleaning a substrate is provided. In this method, a flow of non- Newtonian fluid is provided where at least a portion of the flow exhibits plug flow. To remove particles from a surface of the substrate, the surface of the substrate is placed in contact with the portion of the flow that exhibits plug flow such that the portion of the flow exhibiting plug flow moves over the surface of the substrate. Additional methods and apparatuses for cleaning a substrate also are described.
