Ultra-High Resolution &
Ultra-High Sensitivity Scatterometer with
Thin Film Measurement Capabilities and
Reduced Footprint for 200 mm and 150 mm Wafers
The n&k LittleFoot series are automated metrology systems used to fully characterize and monitor Thin Film and OCD applications for both current and next generation IC processes. With a ~40% smaller Footprint compared to similar metrology tools, the n&k LittleFoot allows for significant savings of wafer fab space without any compromise in effectiveness.
Utilizing patented all-reflective optics, a broadband wavelength range (190 – 1000nm), proprietary optical formulation, and an industry leading signal-to-noise ratio, each system provides the accurate and reproducible data required to monitor subtle changes in critical device parameters (thin film thickness, optical properties, critical dimensions (CD), poly recess profile, sidewall angle) across various key applications.
The n&k LittleFoot’s thin film applications cover both current and next generation thin film measurement demands for R&D and production: Ultra Thin Films and Residual Layers, Multi-Layer Stacks, Inhomogeneous Films, 193 nm and 248 nm ARCs and Resists, Low-κ Films, High-κ Films, and films deposited on practically any substrate.
The n&k LittleFoot-CD’s OCD scatterometry applications cover structures with very large pitches and very small pitches, 2-D and 3-D complex structures including films inside and outside of shallow and deep trenches and contact holes. Because of our patented and unique optical design, n&k Technology offers the highest signal-to-noise ratio and lowest cost of ownership to support your OCD requirement.
