The KLA Zeta 20 is a fully integrated optical profiling microscope. The KLA Zeta 20 performs 3D metrology and imaging. The KLA Zeta 20 uses ZDot technology and multi-mode optics.[1][2][3]
The KLA Zeta 20 is used for three-dimensional surface roughness measurement and step-height measurement.[2][3]
The KLA Zeta 20 supports transparent film thickness measurements, automated defect inspection, and measurement of smooth and rough surfaces.[2][3][4]
The KLA Zeta 20 is used for applications that include solar-cell metrology, patterned sapphire substrate measurements, wafer-edge and chamfer inspection, microfluidic structures, MEMS features, and thin-film surfaces.[4]
