Patent number: 7030039Abstract: A method of and an apparatus for coating a substrate with a polymer solution to produce a film of uniform thickness, includes mounting the substrate inside an enclosed housing and passing a control gas, which may be a solvent vapor-bearing gas into the housing through an inlet. The polymer solution is deposited onto the surface of the substrate in the housing and the substrate is then spun. The control gas and any solvent vapor and particulate contaminants suspended in the control gas are exhausted from the housing through an outlet and the solvent vapor concentration is controlled by controlling the temperature of the housing and the solvent from which the solvent vapor-bearing gas is produced. Instead the concentration can be controlled by mixing gases having different solvent concentrations. The humidity of the gas may also be controlled.Type: GrantFiled: June 30, 2001Date of Patent: April 18, 2006Assignee: ASML Holding N.V.Inventors: Emir Gurer, Tom Zhong, John Lewellen, Edward C.

Publication number: 20010001746Abstract: An improved method and apparatus for coating semiconductor substrates with organic photoresist polymers by extruding a ribbon of photoresist in a spiral pattern which covers the entire top surface of the wafer. The invention provides a more uniform photoresist layer and is much more efficient than are current methods in the use of expensive photoresist solutions. A wafer is mounted on a chuck, aligned horizontally and oriented upward. An extrusion head is positioned adjacent to the outer edge of the wafer and above the top surface of the wafer with an extrusion slot aligned radially with respect to the wafer. The wafer is rotated and the extrusion head moved radially toward the center of the wafer while photoresist is extruded out the extrusion slot. The rotation rate of the wafer and the radial speed of the extrusion head are controlled so that the tangential velocity of the extrusion head with respect to the rotating wafer is a constant.Type: ApplicationFiled: December 20, 2000Publication date: May 24, 2001Inventors: Jung-Hoon Chun, James Derksen, Sangjun Han
