Reflection and Transmission Spectrophotometry
The FilmTek™ 1000 series is an accurate and affordable solution for routine measurement of thin film thickness and refractive index. It combines a fiber-optic spectrophotometer with intuitive, high-performance material modeling software to make daily measurement tasks reliable and simple.
The FilmTek™ 1000M configuration has a small spot size and comes equipped with a manual or optional automatic XY stage to accommodate 75-300mm wafer sizes. The FilmTek™ 1500 measures both transmission and reflection at normal incidence and is ideal for transparent substrates.
FilmTek™ software includes fully user-customizable mapping capabilities to rapidly generate 2D and 3D data maps of any measured parameter. In addition to user-defined patterns, standard map patterns include polar, X-Y, rθ, or linear.
Measurement Capabilities:
FilmTek™ 1000/1500 incorporates SCI’s generalized material model with advanced global optimization algorithms for simultaneous determination of:
- Multiple layer thicknesses
- Indices of refraction [ n(λ) ]
- Extinction (absorption) coefficients [ k(λ) ]
Low cost
The cost of ownership of a FilmTek™ 1000/1500 is a small fraction of comparable instruments.
Intuitive
FilmTek™ 1000 software is designed so that minimal experience in thin film optical design or measurement techniques is required.
