Abstract: A method for meniscus processing a substrate is provided. The method initiates with generating a meniscus spanning at least a length of the substrate. A pre-wetting liquid or vapor is dispensed. A substrate is moved through the dispensed pre-wetting liquid or vapor and the meniscus. The dispensed pre-wetting vapor condenses a pre-wetting liquid over a region of the substrate adjacent to a region of the substrate where the meniscus is generated. The pre-wetting liquid is deposited without substantially generating surface flow of the pre-wetting liquid on the substrate, and the pre-wetting liquid prevents the leading edge of the meniscus from contacting a dry surface region of the substrate.

The method further includes reducing evaporation of fluids from a surface in the substrate processing environment.

Abstract: 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.

Abstract: An apparatus for cleaning a substrate includes an application unit having a top inlet conduit and a bottom plate section. The top inlet conduit has an opening for receiving a non-Newtonian fluid and the bottom plate section has an opening through which the non-Newtonian fluid can flow. The bottom plate section is perpendicular to the top inlet conduit, and a surface of the bottom plate section is disposed above and parallel to a surface of a substrate so as to define a gap between the surface of the bottom plate section and the surface of the substrate. The defined gap has a height configured to create a flow of the non-Newtonian fluid in which a portion of the flow exhibits plug flow, and the plug flow moves over the surface of the substrate to remove particles from the surface of the substrate.

Abstract: A substrate is moved in a linear direction simultaneously between a processing face of an upper proximity head and a processing face of a lower proximity head. As the substrate is moved, a first meniscus of processing liquid is generated between the processing face of the upper proximity head and a top surface of the substrate, and a second meniscus of processing liquid is generated between the processing face of the lower proximity head and a bottom surface of the substrate. The first meniscus has a meniscus protrusion extending in the linear direction in which the substrate is moved and positioned on a trailing side of the first meniscus relative to the linear direction in which the substrate is moved. The meniscus protrusion is centered on the substrate relative to a diameter of the substrate as measured perpendicular to the linear direction in which the substrate is moved.

An applicator is defined to extend over the substrate holder to dispense a cleaning material onto a surface of the substrate when present on the substrate holder. The applicator is defined to apply a downward force to the cleaning material on the surface of the substrate. In one embodiment the cleaning material is gelatinous.

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.

The opening is slightly larger than the substrate such that a gap exists between the substrate and the opening. Means for reducing a size and frequency of entrance and/or exit marks on substrates is provided, the means aiding and encouraging liquid from the meniscus to evacuate the gap. A method for reducing the size and frequency of entrance and exit marks is also provided.

Abstract: A method for meniscus processing a substrate is provided. The method initiates with generating a meniscus spanning at least a length of the substrate. A pre-wetting liquid or vapor is dispensed. A substrate is moved through the dispensed pre-wetting liquid or vapor and the meniscus. The dispensed pre-wetting vapor condenses a pre-wetting liquid over a region of the substrate adjacent to a region of the substrate where the meniscus is generated. The pre-wetting liquid is deposited without substantially generating surface flow of the pre-wetting liquid on the substrate, and the pre-wetting liquid prevents the leading edge of the meniscus from contacting a dry surface region of the substrate.

Abstract: A substrate is placed on a plurality of support pins within an opening of a carrier, such that a gap exists between the radial perimeter of the substrate and the carrier. The substrate and carrier are passed in a linear direction through a meniscus generated between respective faces of upper and lower proximity heads. Each of the upper and lower proximity heads includes a plurality of meniscus nozzles configured to supply liquid to the meniscus. A plurality of vacuum ports are formed on the respective face of each of the upper and lower proximity heads and are arranged to completely surround the plurality of meniscus nozzles. Liquid of the meniscus is evacuated from the gap between the radial perimeter of the substrate and the carrier so as to reduce a size and a frequency of at least one of entrance or exit marks on the substrate.

Abstract: A method for processing a substrate is provided. The method includes generating a controlled meniscus using a proximity head. The proximity head has a face in close proximity to a surface of the substrate, and the face includes a substantially flat surface. The controlled meniscus is generated by delivering a chemical to the meniscus through discrete nozzles formed in the face of the proximity head. The method includes moving the proximity head over the substrate so that an area of contact between the meniscus and the surface of the substrate moves from a first location to a second location on the substrate. The moving of the proximity head causes a chemical remainder to be left behind on the surface of the substrate at the first location. The chemical remainder being a layer of the chemical from the meniscus that adheres to the surface of the substrate.
