Product Overview

DoE/Diffuser detection equipment

AIT DOE/Diffusei # testing equipment is mainly used to detect the diffraction performance parameters of wafer chip, and the regular diffraction image after laser diffraction through the chip

product details

Application Area

Measurement of diffraction performance of chips in semiconductor field


Features and Advantages

High precision visual positioning to ensure the accuracy of chip inspection position

Adjustable imaging systems - Compatible with different types of chip detection

Self developed software algorithm with complete functions to meet different customer needs


Technical Parameters

Repetitive positioning accuracy 3um

UPH:2500-3500
