Ultra-Fast Spectroscope Ellipsometry
ULVAC have taken ellipsometry to the next level with an innovative and unique snapshot method for measurement. The UNECS range provides high speed, accurate and repeatable measurements in a compact and affordable form. UNECS ellipsometers measure as fast as 20ms per point. Compared to conventional ellipsometers, ULVAC's snapshot technology is also highly reliable and low maintenance, contain fewer moving or consumable parts.
Automatic Ellipsometry
The UNECS automatic range is available in 3 models, for 150mm, 200mm and 300mm diameter samples. An auto mapping R-θ sample stage and auto focus system can measure film thickness across the full surface of a sample. Thickness maps can be produced in 2D and 3D, with thickness distribution displayed with a colour key.
Measurements are high-speed, as fast as 20ms per point. There are 2 supported spectral ranges, the standard 530nm to 750nm and a visible wavelength spectral range between 380nm to 760nm.
With ULVAC's novel snapshot measurement system, the UNECS ellipsometers are dependable and easy to maintain. There are no moving parts in the measurement system, and the only consumable part is the halogen bulb light source. ULVAC UNECS ellipsometers can be relied up for fast, efficient and cost-effective measurement in demanding environments.
