What is an ellipsometer? Analyzing Precision Step Height and Semiconductor Wafer Thickness

Analyzing Precision Step Height and Semiconductor Wafer Thickness

• For semiconductor wafer thickness and step height analysis, EUROCALTECH employs cutting-edge technology.

• Key elements in the semiconductor sector.

The thickness of semiconductor wafers measured by laser.

• Computer-controlled selection of wavelength and angle of incidence is a characteristic of the VASE® variable-angle spectroscopic ellipsometer.

• Light is supplied from UV to NIR by the Xenon lamp.

• 193 nm to 1700 nm are covered by stacked Si/InGaAs detectors.

• AutoRetarderTM is used by VASE® in a rotating analyzer ellipsometer setup.
