Publication number: 20070141846Abstract: Disclosed herein is a rapid thermal processing system. The rapid thermal processing system comprises a chamber having an inner surface with a cross-section in a multi-line shape consisting of a plurality of arcs separated from each other while having the same radius and the center, and a plurality of lines connecting the arcs. The chamber overcomes disadvantages of a conventional circular-shaped chamber and the square-shaped chamber. Furthermore, a quartz window has an outer peripheral surface consisting of a combination of a tilt surface, a perpendicular surface, and a round surface, so that even though the quartz window is mounted on the chamber in an inversed state, sealing between the chamber and the quartz window can be maintained. Components of an edge ring are connected by means of a double connecting structure, thereby ensuring a high resistance against thermal deformation compared with the prior art.Type: ApplicationFiled: August 26, 2004Publication date: June 21, 2007Inventor: Won Sik Nam

Patent number: 6837589Abstract: Disclosed herein is a heater module of a rapid thermal processing apparatus. The heater module comprises a heater reactor provided with reflectors, lamps, a cooling gas inlet unit, a quartz window, a quartz window fixing unit, and a cooling gas outlet unit. According to the present invention, since the lamps, reflectors and the like provided in the heater module are cooled during or after thermal processing steps, it is possible to maintain smooth operation thereof, to extend its usage life, and to reduce a preparation time of thermal processing steps. Further, as the respective reflectors adopt an independent structure for allowing the respective lamps to be installed therein in a one-on-one fashion, it is possible to achieve accurate control of a heating source. Furthermore, the lamps adopt a structure capable of effectively reflecting light emitted therefrom, resulting in an improvement in a thermal efficiency.Type: GrantFiled: July 23, 2003Date of Patent: January 4, 2005Assignee: Kornic Systems CorporationInventor: Won-Sik Nam
