Ellipsometry and Reflectometry Systems

FilmTek 2000 PAR-SE

Multi-angle deep UV reflectometry and ellipsometry for accurate thin film and multi-layer characterization

FilmTek 2000 PAR-SE

Combining patented Multi-Angle Differential Polarimetry (MADP) and Differential Power Spectral Density (DPSD) technology, the FilmTek™ 2000 PAR-SE utilizes multi-angle and multi-modal data collection to independently measure film thickness and index of refraction. By independently measuring index and thickness, the FilmTek 2000 PAR-SE is far more sensitive to changes in films, particularly films within multi-layer stacks, than existing metrology tools that rely on conventional ellipsometry or reflectometry techniques. The FilmTek 2000 PAR-SE is a fully-integrated package, paired with advanced material modeling software to make even the most rigorous measurement of patterned wafers reliable and intuitive.

Measurement Capabilities

Enables simultaneous determination of:

  • Multiple layer thicknesses
  • Indices of refraction [ n(λ) ]
  • Extinction (absorption) coefficients [ k(λ) ]
  • Energy band gap [ Eg ]


  • Composition (e.g., %Ge in SiGex, % Ga in GaxIn1-xAs, %Al in AlxGa1-xAs, etc.)
  • Surface roughness
  • Constituent, void fraction


  • Crystallinity/Amorphization (e.g., of Poly-Si or GeSbTe films)
  • Film gradient

System Components


  • Spectroscopic ellipsometry with rotating compensator design (295 nm - 1700 nm)
  • Multi-angle, polarized spectroscopic reflection (190 nm - 1700 nm)
  • 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)
  • Camera for imaging measurement location
  • Pattern recognition
  • 50 micron spot size
  • Advanced material modeling software
  • Bruker's generalized material model with advanced global optimization algorithms


  • Generalized ellipsometry (4×4 matrix generalization method) for anisotropy measurements (nx, ny, nz)
  • Cassette to cassette wafer handling
  • FOUP and SMIF compatible
  • Pattern recognition (Cognex)

Typical Application Areas

Virtually all translucent films ranging in thickness from less than 1 Å to approximately 150 µm can be measured with high precision. Typical application areas include:

Multi-layer Thin Films

Collect accurate, precise production measurements of thin films and multi-layers on patterned device wafers for front and back-end manufacturing.

Filmtek advanced multi-angle and multi-modal technology enables in-line composition control (e.g., %Ge in SiGex) for thin films, Oxide / Nitride / Cu, CMP process monitoring, and measurement of thin metal oxide thickness (SnO, CuO, InO) with sub-Angstrom repeatability to prevent non-wet open failures in bonding processes.


Perform fully-automated film thickness and refractive index measurements of oxide, nitride, oxide/nitride, ONO, amorphous carbon, resist, and oxide/polysilicon/oxide films on patterned device wafers.

Fully-automated FilmTek ellipsometry and reflectometry tools feature cassette-to-cassette wafer handling, 50µm spot size, pattern recognition, and SECS/GEM with a best-in-class combination of performance and price.

New Materials

Characterize new materials with a wide range of rapid, accurate, and reliable R&D measurement capabilities.

FilmTek benchtop tools with automated wafer mapping enable measurements of multiple layer thicknesses, indices of refraction [n(λ)], extinction (absorption) coefficients [k(λ)], energy band gap [Eg], composition (e.g., %Ge in SiGex, % Ga in GaxIn1-xAs, %Al in AlxGa1-xAs, etc.), surface roughness, constituent / void fraction, crystallinity / amorphization (e.g., degree of crystallinity of Poly-Si or GeSbTe films), and film gradient.

Unknown/Complex Materials

Independently and unambiguously determine thickness (t), refractive index (n), and extinction coefficient (k) for unknown materials.

FilmTek combined multiple-angle reflectometry and rotating compensator design ellipsometry systems deliver unprecedented performance with high-throughput automated mapping of patterned and un-patterned samples, 0.03 Angström repeatability for thin films, an extended thickness range from bare substrate to 50µm, and sub-Angström accuracy for complex, multi-layer thin film structures.
