Patent number: 11975422Abstract: Embodiments described herein provide for devices and methods for retaining optical devices. The devices and methods described herein provide for retention of the substrate without contacting sensitive portions of the substrate. The devices and methods utilize retention pads or vacuum pins to contact the exclusion zones i.e., inactive areas of the substrate to retain the substrate and prevent the substrate from moving laterally. Additionally, a holding force retains the substrate in the vertical direction, without contacting the substrate. The methods provide for adjusting the devices to account for multiple geometries of the substrate. The methods further provide for adjusting the devices, such as adjusting a gap between the optical device and a suction pad, to alter the holding force of the devices on the optical devices.Type: GrantFiled: December 2, 2022Date of Patent: May 7, 2024Assignee: Applied Materials, Inc.Inventors: Yaseer Arafath Ahamed, Kangkang Wang, Benjamin B. Riordon, James D. Strassner, Ludovic Godet

Publication number: 20240075492Abstract: An optical device coating assembly is provided. The optical device coating assembly includes a substrate support operable to retain an optical device substrate. The coating assembly further includes a first actuator connected to the substrate support. The first actuator is configured to rotate the substrate support. The coating assembly includes a holder configured to hold a coating applicator against an edge of the optical device substrate when the optical device substrate is rotated on the substrate support and a second actuator operable to apply a force on the holder in a direction towards the substrate support. The second actuator is a constant force actuator.Type: ApplicationFiled: November 10, 2023Publication date: March 7, 2024Inventors: Kangkang WANG, Yaseer Arafath AHAMED, Yige GAO, Benjamin B. RIORDON, Rami HOURANI, James D. STRASSNER, Ludovic GODET, Thinh NGUYEN

Publication number: 20230227276Abstract: Embodiments of the present disclosure generally relate to optical devices. More specifically, embodiments described herein relate to apparatuses and methods for gripping optical devices. In an embodiment, an apparatus for gripping an optical device includes a base coupled to a proximal end of a stem extending from a bottom surface of the base. The apparatus also includes a plurality of arms movably coupled to the bottom surface of the base. The plurality of arms are coupled to an actuator operable to move the plurality of arms laterally along a X-Y plane parallel to the bottom surface of the base. In some embodiments, the apparatus includes a suction pad operable to provide a noncontact vertical suction force.Type: ApplicationFiled: January 9, 2023Publication date: July 20, 2023Inventors: Yaseer Arafath AHAMED, Neal RICKS, James D.
