    摘要: Provided is a method of transferring a semiconductor wafer to a single-side polishing apparatus without forming scratches on the surface of the semiconductor wafer. The method includes: starting to splay the liquid from each spray hole; placing the semiconductor wafer on the retainer portion to hold a surface of the semiconductor wafer by suction without contact, and raising the tray to attach the semiconductor wafer to the polishing head, wherein a period of time from a point at which the semiconductor wafer is held by the retainer portion to a point at which the attaching of the semiconductor wafer W to the polishing head is completed is 5 s or more, or wherein a ratio of a total area of the protrusions to an area of the semiconductor wafer is 15% or more.

    摘要: A machine tool includes a workpiece spindle unit (15) including a workpiece spindle (17) and a workpiece spindle motor (20) and includes a tool spindle unit (25) including a tool spindle (27) and a tool spindle motor. The machine tool further includes a first-axis movement mechanism (6) and a second-axis movement mechanism (9) relatively moving, in a plane including an axis of the workpiece spindle (17) and an axis of the tool spindle (27), the workpiece spindle unit (15) and the tool spindle unit (25) in a first axis direction and a second axis direction intersecting the first axis direction, respectively, and further includes a controller. The tool spindle unit (25) is arranged such that the axis of the tool spindle (27) intersects the axis of the workpiece spindle (17). The controller relatively moves the workpiece spindle unit (15) and the tool spindle unit (25) along the axis of the tool spindle (27) through combined operation of the first-axis movement mechanism (6) and second-axis movement mechanism (9), thereby grinding a workpiece (W) with a cup grindstone (T).

    摘要: A component in a CMP tool disclosed herein having a surface and a hydrophobic layer deposited on the surface. In one example, the component is a component for delivering a fluid in a CMP tool. The component for delivering a fluid in a CMP tool includes an elongated member having a first end and a second end, and an elongated upper surface extending between the two ends. A hydrophobic layer is deposited on the elongated upper surface. In another example, the component is a ring shaped body having an upper side and a lower side. A hydrophobic layer is deposited on the inner surfaces of both the upper and lower sides. In another example, the component is a disk shaped body having a top surface, bottom surface, and ledge defined by the top and bottom surfaces. A hydrophobic layer is deposited on the surfaces and the ledge.
