Patent number: 7972483Abstract: A method for material processing utilizing a material processing system to perform a process. The method performs a process (510), measures a scan of data (520), and transforms the data scan (530) into a signature (540) including at least one spatial component. The scan of data (530) can include a process performance parameter such as an etch rate, an etch selectivity, a deposition rate, a film property, etc. The signature (540) can be stored (550), and compared with either a previously acquired signature or with an ideal signature (560).

Publication number: 20090311634Abstract: A method of patterning a thin film on a substrate is described. The method includes forming a sacrificial structure over the thin film, and forming a photo-resist layer over the sacrificial structure. The sacrificial structure has anti-reflective properties, comprises silicon and is capable of withstanding the photo-resist layer removal process and the stress induced during the spacer layer deposition.
