    A double-focus polarization microscope is impractical for surface tracking and linewidth measurement due to phase curvature. An alternative double-aperture microscope design reduces this effect, offering a practical solution.

    Area of Science:

    • Optical microscopy
    • Metrology
    • Surface analysis

    Background:

    • Accurate surface tracking and linewidth measurement are crucial in fields like semiconductor manufacturing.
    • Existing optical techniques face limitations in precision and practicality.

    Purpose of the Study:

    • To evaluate two optical techniques for surface tracking and linewidth measurement.
    • To identify a practical and effective optical arrangement for high-precision measurements.

    Main Methods:

    • Computer modeling and experimental measurements were used to assess a double-focus polarization microscope.
    • An alternative double-aperture microscope configuration was designed and evaluated.

    Main Results:

    • The double-focus polarization microscope exhibited impracticality for surface tracking and linewidth measurement due to a phase curvature effect.
