  • Apparatus and method for measuring digital imager, package and wafer bow and deviation from flatness
    Patent number: 6724487
    Abstract: Apparatus for measuring the surface profile of a sample, includes a fixture for locating a surface of a transparent optical flat relative to a surface of a sample; a low-coherence light interferometer having an optical probe coupled to an XY scanning frame for scanning the surface of the sample through the transparent optical flat to produce interferometric data signals representing the distances between the optical flat surface and the surface of the sample; and a computer system responsive to the interferometric data signals for generating a surface profile of the sample using a best fit to a plane.
    Type: Grant
