11 August 2008 Transparent film profiling and analysis by interference microscopy
Author Affiliations +
A white-light interferometer with new signal analysis techniques provides 3D top surface and thickness profiles of transparent films. With an additional change from conventional object imaging to pupil-plane imaging, the same instrument platform provides detailed properties of multilayer film stacks, including material optical properties. These capabilities complement conventional surface-topography measurements on the same platform, resulting in a highly flexible tool.
