Patent number: 11297745Abstract: An active thermal management system for electronic devices comprises: a heat spreader having an internal channel; a thermally conductive body moveably positioned in the internal channel; and two or more electronic devices in thermal contact with a back surface of the heat spreader and positioned adjacent to the internal channel. A location of the thermally conductive body within the internal channel determines a path for heat flow from the back surface to a front surface of the heat spreader. The location of the thermally conductive body within the internal channel may be selected to minimize a temperature differential (?T) between the electronic devices.Type: GrantFiled: March 20, 2019Date of Patent: April 5, 2022Assignee: THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOISInventors: William P. King, Nenad Miljkovic, Patricia B Weisensee, Beomjin Kwon, Tianyu Yang

Patent number: 9498866Abstract: In one embodiment, a method for cleaning a surface of a polishing pad includes conditioning the polishing pad surface and rotating the conditioned polishing pad surface. The method also includes spraying the polishing pad surface to lift debris from the conditioned polishing pad surface. The method further includes vacuuming the debris from the polishing pad surface downstream from where the condition occurs, wherein downstream is defined by a rotational direction of the polishing pad. In another embodiment, a processing station including a rotatable platen, a substrate carrier head, a polishing fluid delivery system, a conditioner, a spray nozzle, and a vacuum system is provided. The conditioner is disposed between the substrate carrier head and the spray nozzle. The vacuum system is configured to vacuum the polishing pad surface. The vacuum system is downstream from the conditioner, defined by a rotation of the platen.Type: GrantFiled: March 5, 2014Date of Patent: November 22, 2016Assignee: APPLIED MATERIALS, INC.Inventors: Christopher Heung-Gyun Lee, Thomas Ho Fai Li, Tianyu Yang
