Nanoimprint Resists

Nanoimprint Lithography (NIL) is a straight forward, low cost, and high throughput capable technology for the fabrication of nanometer scaled patterns. Main application fields are photonics, next generation electronics, as well as bio- and sensor applications.

micro resist technology GmbH has provided tailor-made resist formulations for nanoimprint lithography (NIL) since 1999. The unique key features of our products are outstanding film forming and imprinting performance beside excellent pattern fidelity and plasma etch stability. Besides our highly innovative material developments in close contact to industrial needs, our strength is the ability to adjust our materials in film thickness as well as addressing certain needs of the specific use cases within the formulation. Our nanoimprint resists are mostly applied as an etch mask for pattern transfer into various substrates, like Si, SiO2, Al or sapphire.

Our portfolio covers materials for the classical thermal NIL (T-NIL), in which a thermoplastic polymer is used, as well as UV-NIL, in which a liquid formulation is photo crosslinked upon photo exposure. With our technological expertise and know-how we are able to find the right material for your process and applications. Please contact us for your technical support!
