Developed with the Nobel Prize winning graphene group at Manchester University, UK, nanoETCH systems are unique in providing the fine control needed for substrate and device preparation in world-leading 2D materials research.

Headed by Prof. Andre Geim, the graphene group at Manchester University received their first etching system from Moorfield when they started their 2D materials research over 10 years ago. Since then, the system has become a critical part of all experimental work.

The nanoETCH system is optimised for providing the fine control required for substrate and device preparation in graphene and 2D materials research. For substrates, it allows for production of optimal microscopic topography and chemistry that is needed for producing large monolayer crystal flake sizes by mechanical exfoliation. For devices, unparalleled fine plasma control enables patterned etching in a gentle manner that does not affect other crucial structures that are present.

Moorfield technology is unique and offers unmatched performance for these applications. In recognition of this, multiple nanoETCH systems have been recently installed into the new National Graphene Institute in the UK.
