EVG®6200 NT Mask Aligner: State-of-the-Art Mask Alignment Technology

The EVG®6200 NT is known for its automation reliability and flexibility, offering advanced mask alignment technology on a compact footprint area together with the maximum throughput, optimized total cost of ownership, and advanced alignment features.

The EVG®6200 NT has operator-friendly software, reduced time for mask and tooling modifications, and effective global service and support, making it the perfect solution for any manufacturing environment.

The EVG6200 NT or the fully-housed EVG6200 NT Gen2 mask alignment systems are available in automated or semi-automated configuration and are equipped with integrated vibration isolation, achieving excellent exposure results for a wide range of applications, such as exposure of thin and thick resists, patterning of deep cavities and comparable topographies, as well as the processing of thin and fragile materials such as compound semiconductors.

In addition, EVG’s proprietary SmartNIL technology works on both semi-automated and fully automated system configurations.
