EVG®6200 NT

Mask Alignment System
(semi-automated / automated)

The EVG®6200 NT mask aligner is a versatile tool for optical double-side lithography and wafer sizes up to 200 mm.

Known for its automation flexibility and reliability, the EVG6200 NT provides state-of-the-art mask alignment technology on a minimized footprint area combined with the utmost throughput, advanced alignment features and optimized total cost of ownership. Operator-friendly software, minimized time for mask and tooling changes, as well as efficient worldwide service and support makes it the ideal solution for any manufacturing environment. The EVG6200 NT or the fully-housed EVG6200 NT Gen2 mask alignment systems are available in semi-automated or automated configuration and equipped with integrated vibration isolation to achieve 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 processing of thin and fragile materials such as compound semiconductors. Furthermore, the EVG’s proprietary SmartNIL technology is supported on both semi-automated and fully automated system configurations.
