Patent number: 7767956Abstract: Methods and systems for evaluating and controlling a lithography process are provided. For example, a method for reducing within wafer variation of a critical metric of a lithography process may include measuring at least one property of a resist disposed upon a wafer during the lithography process. A critical metric of a lithography process may include, but may not be limited to, a critical dimension of a feature formed during the lithography process. The method may also include altering at least one parameter of a process module configured to perform a step of the lithography process to reduce within wafer variation of the critical metric. The parameter of the process module may be altered in response to at least the one measured property of the resist.Type: GrantFiled: December 4, 2008Date of Patent: August 3, 2010Assignee: KLA-Tencor Technologies Corp.Inventors: Suresh Lakkapragada, Kyle A.

Patent number: 7433047Abstract: Runout characterization is performed on a moving body by positioning a light source and optical sensor at a nominal distance from the moving body, with a beam directed from the light source against a surface of the moving body. The reflected light is detected at a sampling rate with the optical sensor as the moving body moves, and a data stream of the measurements over time is stored. In the case where an interferometer is used as the optical sensor, relative distance measurements are made. The data stream is analyzed to detect repeating signatures in the data stream, where the signatures represent features on the surface of the moving body. At least one of the features is selected as a reference, and the data stream is processed into segments based on the reference, where each segment represents one period of motion of the moving body. The data segments are overlaid on top of each other to produce ordered sets of data points within the segments.Type: GrantFiled: February 16, 2007Date of Patent: October 7, 2008Assignee: KLA-Tencor CorporationInventors: David R.
