发明名称 Method and system for measuring threshold length
摘要 A method and system for measuring threshold length of a planarization process, and for comparing the planarization abilities of such processes. The method and system measure a thickness profile of a film on a blanket wafer, and from the thickness profile, a threshold length is calculated.
