Patent number: 5801961Abstract: Semiconductor processing tools in a semiconductor processing facility are coupled to communicate with a power management system. The power management system monitors the power consumption status of each of the semiconductor processing tools. Using the power consumption status of each of the semiconductor processing tools, the power management system stages the operation of the semiconductor processing tools so as to maintain the power consumption of the semiconductor processing facility below a predefined maximum power consumption. Limiting the power consumption to less than the predefined maximum power consumption reduces the per die processing costs without incurring the expense of building a new semiconductor processing facility or without modifying the semiconductor processing tools for larger batch sizes or for greater throughput.Type: GrantFiled: December 3, 1996Date of Patent: September 1, 1998Assignee: Moore Epitaxial, Inc.Inventors: Gary M. Moore, Michael Peterson, Steven C. Beese

Patent number: 5710407Abstract: A novel rapid thermal process (RTP) reactor processes a multiplicity of wafers or a single large wafer, e.g., 200 mm (8 inches), 250 mm (10 inches), 300 mm (12 inches) diameter wafers, using either a single or dual heat source. The wafers or wafer are mounted on a rotatable susceptor supported by a susceptor support. A susceptor position control rotates the wafers during processing and raises and lowers the susceptor to various positions for loading and processing of wafers. A heat controller controls either a single heat source or a dual heat source that heats the wafers to a substantially uniform temperature during processing. A gas flow controller regulates flow of gases into the reaction chamber. Instead of the second heat source, a passive heat distribution is used, in one embodiment, to achieve a substantially uniform temperature throughout the wafers. Further, a novel susceptor is used that includes a silicon carbide cloth enclosed in quartz.Type: GrantFiled: June 7, 1995Date of Patent: January 20, 1998Assignee: Moore Epitaxial, Inc.Inventors: Gary M. Moore, Katsuhito Nishikawa

Patent number: 5601107Abstract: A process gas supply system at the gas supply point includes an automated means for evacuating gas in a process line fed by the process gas supply system when an abnormal event occurs. The process gas supply system of this invention eliminates the need for any special valves or piping at the point of use of the process gas as well as the need for a return line from the point of use to the process gas supply system to purge the process line. A process gas is contained in a cylinder under pressure. The cylinder is coupled to a process line by the process gas supply system. The process gas supply system includes a gas flow controller and an automatic evacuation system. The gas flow controller controls the supply of the process gas from the cylinder to the process line. In an abnormal event, process gas flow from the cylinder is blocked by the gas flow controller and the automatic evacuation system evacuates the process gas not only from the gas flow controller, but also from the process line.Type: GrantFiled: May 18, 1995Date of Patent: February 11, 1997Assignee: Moore Epitaxial, Inc.Inventors: Gary M. Moore, Richard S. Pairish

Patent number: 5580388Abstract: A multi layer RTP reactor susceptor includes a first layer which has a multiplicity of thin components that are preferably silicon carbide, graphite, or silicon carbide coated graphite with a thickness less than about 6 mm, with an emissivity such that the first layer radiates heat, and with thermal heat transfer characteristics such that the first layer facilitates maintaining a substrate or substrates supported by the susceptor at a uniform temperature, and facilitates maintaining uniform process gas characteristics over the substrates. A second layer of the susceptor is transparent to the heat source of the RTP reactor and provides a rigid, stable platform for the first layer.Type: GrantFiled: May 30, 1995Date of Patent: December 3, 1996Assignee: Moore Epitaxial, Inc.Inventor: Gary M.

Patent number: 5207835Abstract: A barrel epitaxial reactor having a greater batch capacity than prior art barrel epitaxial reactors which produces an epitaxial layer quality at least as good as that produced by the prior art barrel epitaxial reactors is disclosed. The batch capacity of prior art barrel epitaxial reactors is improved by increasing the reaction chamber size and increasing the radiant heat source so that a uniform temperature is maintained over a larger flat zone in the reaction chamber. Also, forced air flow from the blower of the prior art reactor is distributed so that a positive air flow is maintained along the exterior wall of the reaction chamber and consequently the wall is maintained at a uniform cold temperature relative to the temperature of the reaction chamber.Type: GrantFiled: February 9, 1990Date of Patent: May 4, 1993Assignee: Moore Epitaxial, Inc.Inventor: Gary M.
