Patent number: 5380682Abstract: A wafer processing cluster tool, having one or more load-locks, is provided with one or more batch preheating modules that receive wafers only from the cluster tool transport module at the internal vacuum pressure of the machine. The loading, unloading, handling and processing of wafers in the machine can occur while other wafers are being preheated. The preheat module has a vertically moveable rack and is loaded with various sized batches of wafers with no vacant positions between them. Wafer shaped shields may occupy positions adjacent top and bottom wafers to cause them to heat the same as other wafers in the rack. Infrared lamps positioned outside of quartz windows heat wafers in the preheat module. The rack may rotate to improve heating uniformity. Temperature sensors, such as pyrometers, that do not contact the wafers being preheated, measure temperature for control of the heating of the lamps.Type: GrantFiled: November 3, 1993Date of Patent: January 10, 1995Assignee: Materials Research CorporationInventors: Richard C. Edwards, Michael S. Kolesa, Hiroichi Ishikawa

Patent number: 5352248Abstract: A method of measuring and controlling the temperature of articles stacked in parallel in a chamber. A pyrometer is positioned outside of a chamber and directed, either directly or with mirrors, through a window in the chamber wall so that only energy from wafers removed from the ends of the stack is received by the pyrometer. The pyrometer is inclined at an angle so that substantially all energy from the opposite side of the stack and reflected through spaces between facing parallel pairs of wafer surfaces will have been reflected a large number of times by the wafers before entering the pyrometer. Thus, regardless of the emissivity or transmissivity of the wafers, the energy incident upon the pyrometer will approach that emitted by a black body of the same temperature as the wafers, and the temperature read by the pyrometer will be independent of the emissivity or transmissivity of the wafers.Type: GrantFiled: April 15, 1992Date of Patent: October 4, 1994Assignee: Materials Research CorporationInventors: Hiroichi Ishikawa, Michael S. Kolesa

Patent number: 5350899Abstract: A method and apparatus are provided for measuring the temperature of articles such as semiconductor wafers in a sealed chamber of a processing apparatus such as a batch preheating module of a semiconductor wafer processing cluster tool. Wafers of generally known nominal diameter and coefficient of thermal expansion are placed at a known initial temperature into a processing chamber which is then sealed. A pair of beams of parallel light are passed by opposite edges of the wafer and the uninterrupted light from both beams are detected and summed. When the wafer is heated in processing, light from the beams is measured again. Expansion of the wafers changes the amount of uninterrupted light detected, and the changed amount of light is measured. From the measurement, the initial temperature, the nominal diameter and the known coefficient of expansion, processing temperature is calculated and displayed or used to control chamber heaters.Type: GrantFiled: April 15, 1992Date of Patent: September 27, 1994Inventors: Hiroichi Ishikawa, Michael S. Kolesa
