EVG®50: Automated Metrology System for Bonded Stacks and Single Wafers

The EVG50 (completely automated independent tool) and the Inline Metrology Module (combined in EVG’s high-volume-manufacturing systems) provide highly precise measurements at high speed, making use of various measurement techniques for a huge number of applications.

The application range of the tool covers multi-layer thickness measurements for determining the total thickness variation (TTV) of an intermediate layer, inspecting bond interfaces and measuring resist thickness while satisfying the most demanding needs of the yield-driven semiconductor industry.
