Gemini Series

The n&k Gemini series are automated metrology systems used to fully characterize and monitor Thin Film and OCD applications for both current and next generation IC processes. Capable of simultaneous Reflectance and Transmittance measurements the Gemini series is ideal for applications with transparent substrates (i.e., Photomasks, SiC Wafers, Quartz Wafers, Flat Panels, etc.).

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.
