Spectroscopic Ellipsometer - FilmTek™ 2000SE

The FilmTek™ 2000SE is a high performance spectroscopic ellipsometer for thin film characterization that measures from the deep UV to NIR (190-1700nm). Based on a rotating compensator design, the FilmTek™ 2000SE spectroscopic ellipsometer combines spectroscopic ellipsometry with multiple angle reflectometry to make it ideally suited for measuring the thickness and optical constants (n & k) of very thin films. The FilmTek™ 3000SE spectroscopic ellipsometer adds transmission measurement capability in addition to spectroscopic ellipsometry and DUV reflectometry. The FilmTek™ 2000SE spectroscopic ellipsometer utilizes SCI's material modeling software to provide an affordable and reliable thin film measurement tool for the simultaneous measurement of film thickness, index of refraction, and extinction coefficient.

  • Spectroscopic reflection (190nm-1700nm) of polarized light at multiple angles
  • Spectroscopic ellipsometry with rotating compensator design (300nm-1700nm)
  • Measures film thickness and index of refraction independently
  • Multi-Angle Differential Polarimetry (MADP) technology with SCI’s patented Differential Power Spectral Density (DPSD) technology
  • Ideal for measuring ultra-thin films (0.03 Å repeatability on native oxide)
  • Optional generalized ellipsometry (4x4 matrix generalization method) for anisotropy measurements (nx, ny, nz)
  • Ideal for measuring advanced thin films
