Plasma Process Technology
Thin Film Metrology
The laser ellipsometer SE 400adv measures thickness and refractive index of transparent thin films, featuring measurement speed, Sub-Angstrom precision in thickness, and per mille accuracy in refractive index determination.
The stabilised HeNe laser guarantees a precision of 0.1 Å for thin film thickness measurement of ultra-thin single layers.
The multiple angle manual goniometer with superior performance and angle accuracy of this laser ellipsometer allows measuring refractive index, extinction coefficient, and film thickness of single films and layer stacks.
The measurement speed of the SENTECH SE 400adv laser ellipsometer enables users to monitor single film growth and endpoint detection or to map samples for homogeneity.

The SENTECH SE 400adv is adaptable to your needs by mapping up to 200 mm, liquid cells for in-situ measurement, video camera, autofocus, simulation software, and certified standard wafer.
The SENTECH SE 400adv laser ellipsometer can be utilised to characterise single films and substrates from selectable, application-specific angles of incidence. The auto-collimating telescope ensures precise measurement on most kinds of absorbing or transparent substrates with a flat, reflective surface. The fully integrated support of multiple angle measurements (40 ° – 90 ° in steps of 5 °) can be used for determining the thickness, refractive index, and extinction coefficient of layer stacks. Multiple angle measurements are also applied for absolute thickness measurement to compensate for the ambiguity of thickness measurement in laser ellipsometry.
The SE 400adv is the SENTECH laser ellipsometer for thickness measurement of ultra-thin single films. The compact tabletop instrument comprises the ellipsometer optics, goniometer, sample platform, auto-collimation telescope, HeNe laser source, and a detection unit. The options of our laser ellipsometer SE 400adv support applications in microelectronics, data storage, display technology, life science, metal processing, and many more leading-edge technologies.
