Beam deviation in the polarizing elements is identified as a significant source of error in existing ellipsometer alignment procedures. A high precision alignment procedure that eliminates these errors is described. This procedure is less time consuming than previous methods, and its accuracy is comparable to the limit of resolution of the ellipsometer (typically 0.01–0.005°). A further advantage of this procedure is that it provides a precise method for the alignment of specimens and lasers with the ellipsometer.

  9. Some ambiguity exists in the previous literature due to the indiscriminate use of the term, alignment, to describe both the alignment of the telescope axes and the calibration of the azimuthal scales of the ellipsometer. In this paper, alignment implies the alignment of the telescope axes, and calibration implies the calibration of the azimuthal scales.

  16. Since the standard sample tables of many commercial ellipsometers do not allow an independent horizontal adjustment of the sample position, a special sample table (e.g., one with linear translation adjustments) may be necessary.
  17. A transparent slide with only one coated slide could be used, but the optical quality of the beam reflected from the back side of the coating is generally unsatisfactory due to interference between the beams reflected from the slide and the coating.
  18. If a source other than the alignment laser is to be used in the measurements, it may be advisable to align the source before the sample table is removed (see Sec. II F).
