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:
One of many embodiments of a substrate preparation system is provided which includes a head having a head surface where the head surface is proximate to a surface of the substrate. The system also includes a first conduit for delivering a first fluid to the surface of the substrate through the head, and a second conduit for delivering a second fluid to the surface of the substrate through the head, where the second fluid is different than the first fluid. The system also includes a third conduit for removing each of the first fluid and the second fluid from the surface of the substrate where the first conduit, the second conduit and the third conduit act substantially simultaneously. In an alternative embodiment, a method for processing a substrate is provided that includes generating a fluid meniscus on a surface of the substrate and applying acoustic energy to the fluid meniscus. The method also includes moving the fluid meniscus over the surface the substrate to process the surface of the substrate.
Abstract:
39 METHOD AND APPARATUS FOR REMOVING CONTAMINATION FROM SUBSTRATE ABSTRACT A CLEANING MATERIAL IS DISPOSED OVER A SUBSTRATE. THE CLEANING MATERIAL INCLUDES SOLID COMPONENTS DISPERSED WITHIN A LIQUID MEDIUM. A FORCE IS APPLIED TO THE SOLID 5 COMPONENTS WITHIN THE LIQUID MEDIUM TO BRING THE SOLID COMPONENTS WITHIN PROXIMITY TO CONTAMINANTS PRESENT ON THE SUBSTRATE. THE FORCE APPLIED TO THE SOLID COMPONENTS CAN BE EXERTED BY AN IMMISCIBLE COMPONENT WITHIN THE LIQUID MEDIUM. WHEN THE SOLID COMPONENTS ARE BROUGHT WITHIN SUFFICIENT PROXIMITY TO THE CONTAMINANTS, AN INTERACTION IS ESTABLISHED BETWEEN THE SOLID COMPONENTS AND THE CONTAMINANTS. THEN, THE SOLID 10 COMPONENTS ARE MOVED AWAY FROM THE SUBSTRATE SUCH THAT THE CONTAMINANTS HAVING INTERACTED WITH THE SOLID COMPONENTS ARE REMOVED FROM THE SUBSTRATE.

PROBLEM TO BE SOLVED: To provide a cleaning apparatus and a method thereof which can remove particulate contamination substance of a sufficiently small size, even if the substance has a shape of a high aspect ratio. SOLUTION: The apparatus for cleaning a substrate 116 is disclosed. The apparatus is provided with a first head unit 110 and a second head unit 112. The first head unit 110 is arranged proximate to the surface of the substrate and is provided with a first row of channels configured to supply a foam to the surface of the substrate. The second head unit 112 is arranged substantially adjacent to the first head unit and proximate to the surface of the substrate. The second head unit is provided with a second and a third row of channels. The second row of channels 112 is configured to supply a fluid to the surface of the substrate. The third row of channels 114 is configured to cause a vacuum to work on the surface of the substrate. COPYRIGHT: (C)2007,JPO&INPIT
