Patent number: 9899242Abstract: A system for heating substrates while being transported between processing chambers is disclosed. The system comprises an array of light emitting diodes (LEDs) disposed in the transfer chamber. The LEDs may be GaN LEDs, which emit light at a wavelength which is readily absorbed by silicon, thus efficiently and quickly heating the substrate. A controller is in communication with the LEDs. The LEDs may be independently controllable, so that the LEDs that are disposed above the substrate as it is moved from one processing chamber to another are illuminated. In other words, the illumination of the LEDs and the movements of the substrate handling robot may be synchronized by the controller.Type: GrantFiled: April 6, 2015Date of Patent: February 20, 2018Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Jason M.
