EVG®7200 LA
The EVG®620 NT is a versatile and reliable mask alignment system designed for both research and high-volume production environments. Its compact footprint and advanced alignment features make it ideal for optical double-side lithography. Available in semi-automated or fully automated configurations, the system meets stringent fab standards and high-volume production requirements.
Equipped with integrated vibration isolation, the EVG®620 NT delivers exceptional exposure results across a wide range of applications, including exposure of thin and thick resists, patterning of deep cavities and complex topographies, and processing of fragile materials such as compound semiconductors. The system supports both standard lithography processes and EVG’s proprietary SmartNIL™ technology, enabling the patterning of extremely small features down to less than 40 nm.
Operator-friendly software, minimised time for mask and tooling changes, and efficient worldwide service and support make the EVG®620 NT an ideal solution for any manufacturing environment.

What is the EVG®7200 LA?
The EVG®7200 Large-Area (LA) UV Nanoimprint System takes nanoimprint lithography (NIL) to panel-sized substrates (Gen substrates), specifically Gen 2 (370 mm × 470 mm) display panel format, powered by the latest evolution of EVG's SmartNIL™ technology. It scales the same imprint process proven on 200 mm round substrates up to large, rectangular panel sizes.
IES is the official UK representative for EV Group (EVG), supplying, installing, and supporting the EVG®7200 LA for customers across the UK.
What applications is it built for?
The EVG®7200 LA is ideal for applications that require large-area patterning — such as displays, wire grid polarizers, biotechnology, and photonic elements — where size reduction isn't possible and maximising substrate utilisation is critical. NIL is a cost-effective method for fabricating nanopatterns on large areas, since it isn't constrained by the optical limitations of conventional lithography and delivers strong pattern fidelity even at the smallest structure sizes.
What resolution can it achieve?
SmartNIL™ technology delivers conformal imprinting results down to 40 nm*, using a highly controllable and robust tooling process, with multi-use soft working stamp technology that adapts to uneven and rough surfaces.
What makes it practical for production use?
The EVG®7200 LA combines ease of use, proven equipment capabilities, and EVG's process expertise, extending nanoimprint lithography to new substrate scales as display, photonics, and biotech applications demand larger patterned areas.
