Specifications

Dimensions (mm) 1,450mm(W) x 2,650mm(D) x 1,885mm(H)
Applicable wafer size 300 mm wafer
Detection capability Micro defects with high sensitivity

With the miniaturization and high layering of semiconductor devices, defect types originating from wafer edges are increasing and detection sizes are becoming smaller. There is a demand for equipment that can detect and classify only the defects that reduce yield from among these diverse defects.

CIEL has completely renewed the optical system of the EZ Series and achieved high-sensitivity, high-throughput inspection with a proprietary optical system. In addition, high-precision defect classification using deep learning technology and the 3D function of the proprietary optical system enable acquisition of high-resolution images including height and depth information, and have enhanced the function to identify defects that should be detected.
