Patent number: 10464184Abstract: Before a first surface of a substrate is polished using a chemical mechanical process, the substrate is transferred to a modification station. The substrate comprises a side wall connected with the first surface at an edge and a second surface opposite to the first surface and also connected to the side wall. The first surface is substantially flat. The side wall is substantially perpendicular to the first surface. The edge of the substrate is modified at the modification station by removing material from a region of the first surface. The side wall of the substrate is a boundary of the region. The modified edge comprises a modified first surface that tapers within the region towards the second surface. The side wall remains substantially perpendicular to the first surface.Type: GrantFiled: May 7, 2014Date of Patent: November 5, 2019Assignee: Applied Materials, Inc.Inventors: Jimin Zhang, Zhihong Wang, Wen-Chiang Tu

Patent number: 10434627Abstract: 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.Type: GrantFiled: November 20, 2015Date of Patent: October 8, 2019Assignee: APPLIED MATERIALS, INC.Inventor: Sreenidhi Attur

Patent number: 10414015Abstract: A polishing apparatus includes a polishing table for supporting a polishing pad and a substrate holding device for pressing a substrate against the polishing pad. The substrate holding device includes an elastic film to form multiple pressure chambers to press the substrate, and a pressure control unit controlling pressure of the pressure chambers. The pressure control unit includes a first flow path connected to a first pressure chamber, and first and second pressure regulation mechanisms. The pressure control unit performs switching control from first pressure regulation mechanism to second pressure regulation mechanism when a set pressure within first pressure chamber reaches a first threshold value. Then, the pressure control unit performs switching control from second pressure regulation mechanism to first pressure regulation mechanism when the set pressure within the first pressure chamber reaches a second threshold value lower than the first threshold value.Type: GrantFiled: August 26, 2016Date of Patent: September 17, 2019Assignee: Ebara CorporationInventors: Makoto Fukushima, Hozumi Yasuda, Shingo Togashi

Patent number: 10322486Abstract: A grinding machine includes a manual rotating handle provided with a rotation detector that outputs a rotation detection signal so that the position of a grinding wheel with respect to a workpiece can be relatively moved in accordance with the rotation detection signal. The grinding machine further includes a grinding wheel, a moving apparatus that moves the position of the grinding wheel with respect to a workpiece W, a proximity detector that outputs a proximity detection signal corresponding to a relative position or a relative distance between the workpiece and the grinding wheel, a manual rotating handle provided with a rotation detector, and a control apparatus that controls the moving apparatus based on the rotation detection signal. The manual rotating handle is provided with a rotational-torque varying apparatus. The control apparatus controls the rotational-torque varying apparatus based on the proximity detection signal.Type: GrantFiled: February 18, 2015Date of Patent: June 18, 2019Assignee: JTEKT CORPORATIONInventors: Hisayuki Nagaya, Kikutoshi Okada, Shinji Nishio, Hidetaka Sugiura
