The substrate is heated on the heating plate while the inert gas is circulating at an extremely small first circulating amount. The substrate is heated further on the heating plate while the inert gas is circulating at a second circulating amount larger than the first circulating amount. Detected is the density of the solvent in the processing chamber. The supply and exhaust amounts of the inert gas are controlled based on the density detected after the start of heating, so that an exhaust amount of the inert gas becomes a predetermined amount for a predetermined period until the solvent density reaches a predetermined density. A necessary control process is performed so that the solvent density reaches the predetermined density when the solvent density has not reached or exceeded the predetermined density after the predetermined period has elapsed.Type: GrantFiled: December 18, 2001Date of Patent: June 3, 2003Assignee: Tokyo Electron LimitedInventors: Hiroshi Shinya, Kazuyoshi Mizumoto, Kazuhisa Hayashida, Eiichi Sekimoto

Patent number: 6524389Abstract: In a processing chamber for performing heat processing for a substrate, gas for purge, for example, N2 is supplied nearly parallel to the substrate placed on a hot plate with a gap forming member between them and toward both the front and rear faces of the substrate. Thus, an atmosphere around the substrate can be exchanged for the gas for purge efficiently, and moreover the atmosphere around the substrate can be exchanged uniformly. Accordingly, heat processing in a low oxygen atmosphere can be performed in a short time, and moreover the total time required for substrate processing can be shortened. Besides, heat processing in the low oxygen atmosphere can be performed uniformly.Type: GrantFiled: May 22, 2000Date of Patent: February 25, 2003Assignee: Tokyo Electron LimitedInventors: Kyoshige Katayama, Yuta Yoshimura, Takeshi Tamura

Patent number: 6508920Abstract: A method for filling recessed microstructures at a surface of a microelectronic workpiece, such as a semiconductor wafer, with metallization is set forth. In accordance with the method, a metal layer is deposited into the microstructures with a process, such as an electroplating process, that generates metal grains that are sufficiently small so as to substantially fill the recessed microstructures. The deposited metal is subsequently subjected to an annealing process at a temperature below about 100 degrees Celsius, and may even take place at ambient room temperature to allow grain growth which provides optimal electrical properties. Various novel apparatus for executing unique annealing processes are also set forth.Type: GrantFiled: August 31, 1999Date of Patent: January 21, 2003Assignee: Semitool, Inc.Inventors: Thomas L. Ritzdorf, E. Henry Stevens, LinLin Chen, Lyndon W. Graham, Curt Dundas

Patent number: 6406541Abstract: Improved methods and apparatus are disclosed for efficiently and precisely adhering and centering particles on tacky areas on a surface containing an array of tacky and non-tacky areas. These improved methods and apparatus for particle attachment and centering involve holding and heating of the surface containing an array of tacky and non-tacky areas with particles adhered thereon for a period of time and at a temperature to allow the particles to adhere and center to the tacky areas. The surface containing the array of tacky and non-tacky areas can be heated either prior to, during or after a step of contacting the array with particles. Either discrete sheets or a continuous moving web of material having a surface containing an array of tacky and non-tacky areas can be employed. Each tacky area of an array of tacky and non-tacky areas has a size and bonding strength suitable for adhesion of one particle thereto in formation of an array.Type: GrantFiled: May 26, 2000Date of Patent: June 18, 2002Assignee: The Regents of the University of CaliforniaInventors: Allan Cairncross, John Edwin Gantzhorn, Jr.

Patent number: 6391112Abstract: A workpiece holding device for a vacuum unit has coolable or heatable transfer plates (2) displaceable independently of one another in a baseplate (1) and each comprising a heat transfer surface (3) which is surrounded by an O-ring (4), is connected to a pipe (5) and, with a workpiece (15) which is pressed against the O-ring (4) by a holder (16), encloses a gap (20). The holder (16) can be locked to the baseplate (1). After lowering of the holder (16) into a closed position and load-free locking to the baseplate (1), the heat transfer plates (2) are pneumatically raised until in each case a stop (23, 22) becomes effective between said heat transfer plates and the holder (16) and determines the width of the gap (20). The gap (20) is then filled via the pipe (5) with a heat transfer medium, e.g. helium. After processing of the workpiece (15), the heat transfer plates (2) are lowered and the holder (16) is released again in a loadfree manner.Type: GrantFiled: February 11, 2000Date of Patent: May 21, 2002Assignee: Unaxis Trading AGInventors: Peter Mahler, Michael Scherer

Patent number: 6372042Abstract: A photo process system for semiconductor wafers prevents air from flowing across the top of a baking region to produce a stable downward laminar air flow in front of baking units disposed at several levels in the baking region. The baking region is located on one side of a housing, and a coating unit for coating a wafer with a photoresist is located on the other side of the housing. The housing has a clean air entrance and air filters at an upper portion thereof, and a clean air discharge opening at the very bottom thereof. An air flow containment dam prevents clean air entering the housing from flowing horizontally at the top of the baking region. Such a horizontal flow of air would otherwise produce turbulence severely affecting the ability of the air to flow downward across the front of the baking units and toward the discharge opening as a laminar air flow. The laminar air flow hardly passes into the baking units and thus, hardly induces temperature variations in the coated wafers that are being baked.Type: GrantFiled: January 14, 2000Date of Patent: April 16, 2002Assignee: Samsung Electronics Co., Ltd.Inventors: Woo-dong Sung, Sam-soon Han, Chang-wook Oh, Jeong-lim Nam

Patent number: 6261365Abstract: When a substrate coated with a coating solution which oxidizes at high temperatures is heat-treated, an oxygen concentration of a treatment atmosphere is lowered when the temperature is low. Next, the substrate is heat-treated in the treatment atmosphere of which the oxygen concentration is lowered. Sequentially, the treatment atmosphere is returned to that with the original oxygen concentration after the passage of a predetermined time after completing the heat treatment. Thereby, the substrate can be heat-treated, with the oxidization of the coating solution being controlled.Type: GrantFiled: March 19, 1999Date of Patent: July 17, 2001Assignee: Tokyo Electron LimitedInventors: Yuji Matsuyama, Yoji Mizutani, Shinji Nagashima, Akira Yonemizu
