Patent number: 9115987Abstract: An optical metrology device simultaneously detects light with multiple angles of incidence (AOI) and/or multiple azimuth angles to determine at least one parameter of a sample. The metrology device focuses light on the sample using an optical system with a large numerical aperture, e.g., 0.2 to 0.9. Multiple channels having multiple AOIs and/or multiple azimuth angles are selected simultaneously by passing light reflected from the sample through a plurality of pupils in a pupil plate. Beamlets produced by the plurality of pupils are detected, e.g., with one or more spectrophotometers, to produce data for the multiple AOIs and/or multiple azimuth angles. The data for multiple AOI and/or multiple azimuth angles may then be processed to determine at least one parameter of the sample, such as profile parameters or overlay error.Type: GrantFiled: December 4, 2013Date of Patent: August 25, 2015Assignee: Nanometrics IncorporatedInventors: Zhuan Liu, Shifang Li
