Patent number: 7605350Abstract: In general, the system provides for soft baking a semiconductor wafer so that photoresist layers on the wafer are free of surface voids or craters. In particular, the system provides for manufacturing a semiconductor wafer having no photoresist craters at the completion of a two-step post-apply resist bake (soft bake) in the fabrication of an integrated circuit. In the system, the semiconductor wafer is coated with resist and then baked at both a low-bake temperature and a high-bake temperature. It is theorized that the lower temperature bake either hardens the resist layer before trapped air expands through the resist or displaces the trapped air while the resist layer remains fluid and returns to its conformal shape.Type: GrantFiled: August 31, 2005Date of Patent: October 20, 2009Assignee: Micron Technology, Inc.Inventors: Paul Shirley, Gordon Haller

Patent number: 6500737Abstract: A system and method for providing substantially defect free rapid thermal processing. The present invention includes a wafer processing system used to process semiconductor wafers into electronic devices. In accordance with the present invention, once the wafer is processed, a shield can be inserted into the reactor to a position between the reactor heating surface and the wafer. The shield causes the temperature of the wafer to be reduced. Once the temperature of the wafer has been reduced to below a predetermined critical temperature, the robot picks up the wafer and removes the wafer from the processing chamber.Type: GrantFiled: June 8, 2000Date of Patent: December 31, 2002Assignee: WaferMasters, Inc.Inventor: Woo Sik Yoo
