Publication number: 20110171355Abstract: A food warming cabinet keeps food warm and on display in serving trays using infrared heaters instead of hot water. The infrared heaters are located below the trays and direct IR at the trays. In an alternate embodiment, the IR heaters can also conduct heat into the trays. Using IR instead of water saves energy because it shortens warm-up time. Using IR also eliminates contaminated water and enables separate and individual temperature control of each tray. Tray temperature is maintained under computer control using contact or optical/IR temperature sensors.Type: ApplicationFiled: January 13, 2010Publication date: July 14, 2011Applicant: PRINCE CASTLE, INCInventors: TERRY TAE-IL CHUNG, JEFF SCHROEDER

The interdependencies of processing tools and the related effect on semiconductor wafers within a processing tool is factored into a mathematical model that considers desired and measured wafer quality parameters in the derivation of specific solutions of sets of possible quality parameter adjustments. A selection process determines a set of adjustments such as one that results in minimal changes to the process.Type: GrantFiled: March 4, 2003Date of Patent: November 17, 2009Assignee: Micron Technology, Inc.Inventors: Sergey A. Velichko, Jeffrey S. Nelson, Roger W. Eagans

Patent number: 7616872Abstract: Temperature measurement and heat-treating methods and systems. One method includes identifying a temperature of a first surface of a workpiece, and controlling energy of an irradiance flash incident on the first surface of the workpiece, in response to the temperature of the first surface. Identifying may include identifying the temperature of the first surface during an initial portion of the irradiance flash, and controlling may include controlling the power of a remaining portion of the irradiance flash. The first surface of the workpiece may include a device side of a semiconductor wafer.Type: GrantFiled: December 14, 2005Date of Patent: November 10, 2009Assignee: Mattson Technology Canada, Inc.Inventors: David M.

Patent number: 7608802Abstract: An apparatus for heat treating semiconductor wafers is disclosed. The apparatus includes a heating device which contains an assembly of light energy sources for emitting light energy onto a wafer. The light energy sources can be placed in various configurations. In accordance with the present invention, tuning devices which are used to adjust the overall irradiance distribution of the light energy sources are included in the heating device. The tuning devices can be either active sources of light energy or passive sources which reflect, refract or absorb light energy. For instance, in one embodiment, the tuning devices can comprise a lamp spaced from a focusing lens designed to focus determined amounts of light energy onto a particular location of a wafer being heated.Type: GrantFiled: April 6, 2006Date of Patent: October 27, 2009Assignee: Mattson Technology, Inc.Inventors: Arnon Gat, Bob Bogart

Publication number: 20090263112Abstract: In light-irradiation heating with a total irradiation time of one second or less, two-stage irradiation is performed, including a first stage of light irradiation of a semiconductor wafer, which irradiation produces an output waveform that reaches a peak at a given emission output; and a second stage of supplemental light irradiation of the semiconductor wafer, which irradiation is started after the peak, producing an emission output smaller than the above given emission output. The emission output in the second stage is two thirds or less than the above given emission output at the peak. The first-stage light-irradiation time is between 0.1 and 10 milliseconds, and the second-stage light-irradiation time is 5 milliseconds or more. This allows the temperature of the semiconductor wafer even at a somewhat greater depth below the surface to be raised to some extent while allowing the surface temperature to be maintained at a generally constant processing temperature.Type: ApplicationFiled: April 10, 2009Publication date: October 22, 2009Inventors: Hiroki Kiyama, Kenichi Yokouchi

Patent number: 7598150Abstract: Methods for compensating for a thermal profile in a substrate heating process are provided herein. In one embodiment, a method of processing a substrate includes determining an initial thermal profile of a substrate resulting from a process; imposing a compensatory thermal profile on the substrate based on the initial thermal profile; and performing the process to create a desired thermal profile on the substrate. In other embodiments of the invention, the initial substrate thermal profile is compensated for by adjusting a local mass heated per unit area, a local heat capacity per unit area, or an absorptivity or reflectivity of a component proximate the substrate prior to performing the process. In another embodiment, the heat provided by an edge ring to the substrate may be controlled either prior to or during the substrate heating process.Type: GrantFiled: November 20, 2006Date of Patent: October 6, 2009Assignee: Applied Materials, Inc.Inventors: Joseph M. Ranish, Bruce E. Adams

Publication number: 20090245761Abstract: Annular reflecting rings are removably mounted on the upper and lower sides of a chamber side portion of a chamber. An annular recessed portion is formed sandwiched between the lower end face of the upper reflecting ring and the upper end face of the lower reflecting ring to surround a holding part for holding a semiconductor wafer. The outer peripheral surface of the recessed portion communicates with a transport opening. The formation of the recessed portion prevents the light emitted from halogen lamps and flash lamps from being non-uniformly reflected around the holding part to enter a semiconductor wafer, thus improving the uniformity of the in-plane temperature distribution in the semiconductor wafer during heat treatment.Type: ApplicationFiled: March 2, 2009Publication date: October 1, 2009Inventor: Toshihiro Nakajima

Publication number: 20090190908Abstract: In an apparatus for heat-treating a substrate, a substrate holder unit including a substrate stage which is made of carbon or a carbon-covered material having high radiation ratio is arranged in a vacuum chamber to be vertically movable. A heating unit including a heat dissipation surface which opposes the substrate stage is provided above the substrate stage in the vacuum chamber. The substrate stage is moved close to the heat dissipation surface to heat the substrate in noncontact with it with radiation heat from the heat dissipation surface. The substrate holder unit includes a radiation plate and a reflection plate.Type: ApplicationFiled: April 3, 2009Publication date: July 30, 2009Applicant: CANON ANELVA CORPORATIONInventor: Masami Shibagaki

Publication number: 20090180766Abstract: In a heat treatment apparatus, a substrate held by a holding part is irradiated with light emitted from halogen lamps to perform preheating thereon and irradiated with a flash of light emitted from flash lamps to perform flash heating thereon. Part of light which is emitted from the halogen lamps and goes toward the flash lamps passes through a window hole formed in a peripheral-light shielding member and enters the substrate held by the holding part, and its energy is used for the preheating on the substrate. On the other hand, the remaining light is blocked out by the peripheral-light shielding member.Type: ApplicationFiled: December 15, 2008Publication date: July 16, 2009Inventor: Tatsufumi Kusuda

Publication number: 20090175606Abstract: An article supports a workpiece during thermal processing. At least three elongated support members, e.g., support pins, extend upwardly from an element such as support arms for supporting the workpiece. Each of the support members includes a first portion adjacent to the workpiece. A second portion extends downwardly from the first portion. The first portion can have a thermal response faster than the thermal response of the workpiece and the second portion can have a slower thermal response. A removable element may be mounted to the support member for adjusting the thermal response of the support member. With removable elements, the support members can be adjusted to cause no net transfer of heat to or from the workpiece.Type: ApplicationFiled: January 8, 2008Publication date: July 9, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Raschid J.
