The MA300 Automated Station based on the microscope working in the UV spectrum (365 nm) is designed for inspection of the elements of IC patterns on semiconductor wafers with the dimensions from 0.18 µm and more.

    The MA300 is equipped with a sextuple electromechanically driven revolving nosepiece. Additionally the Station is equipped with an 150×/0.9 UV objective (the resolution is no less than 3300 lines/mm, designed for 365±10nm wavelength) and a mercury lamp illuminator.

    The Station is equipped with either a manual or a software-controlled stage and a focusing device enabling to inspect the elements of the IC patterns on Ø200 mm semiconductor wafers.
