    摘要: A method and system for cleaning opposed surfaces of a semiconductor wafer having particulate matter thereon. The method includes generating relative movement between a fluid and the substrate. The relative movement is in a direction that is transverse to a normal to one of the opposed surfaces and creates two spaced-apart flows. Each of the flows is adjacent to one of the opposed surfaces that is different from the opposed surface that is adjacent to the remaining flow of the plurality of flows. The fluid has coupling elements entrained therein, and the relative movement is established to impart sufficient drag upon a subset of the coupling elements to create movement of the coupling elements of the subset within the fluid. In this manner, a quantity of the drag is imparted upon the particulate matter to cause the particulate matter to move with respect to the substrate.

    摘要: Systems and methods for cleaning particulate contaminants adhered to wafer surfaces are provided. A cleaning media including dispersed coupling elements suspended within the cleaning media is applied over a wafer surface. External energy is applied to the cleaning media to generate periodic shear stresses within the media. The periodic shear stresses impart momentum and/or drag forces on the coupling elements causing the coupling elements to interact with the particulate contaminants to remove the particulate contaminants from the wafer surfaces.

    摘要: Apparatus, methods, and computer programs for cleaning opposed surfaces of a semiconductor wafer are presented. One apparatus includes first, second, and third valves, and one or more second drains. The first valves are coupled to a supply of rinsing solution and to first throughways that are coupled to an immersion tank above a region in the immersion tank, the region being defined by an area occupied by the substrate when the substrate is disposed vertically on a support within the immersion tank. The second valves are coupled to first drains and to second throughways that are coupled to the immersion tank below the region, and the third valves are coupled to a supply of cleaning solution and to third throughways that are coupled to the immersion tank below the region. Further, the second drains are coupled to fourth throughways that are coupled to the immersion tank above the region.
