摘要

Nanoimprint Lithography has been demonstrated to be one of the most promising next generation techniques for large-area structure replication in the nanometer scale. This fast and low cost method becomes an increasingly important instrument for fabrication of biochemistry, μ-fluidic, μ-TAS and telecommunication devices, as well as for a wide variety of fields in the nm range, like biomedical, nano-fluidics, nano-optical applications, data storage, etc. Due to the restrictions on wavelength and the enormous development works, linked to high process and equipment costs on standard lithography systems, nanoimprint lithography might become a real competitive method in mainstream IC industry. There are no physical limitations encountered with imprinting techniques for much smaller replicated structures, down to the sub-10nm range [1]. Among several Nanoimprint lithography techniques results of two promising methods, hot embossing lithography (HEL) and UV-nanoimprinting (UV-NIL) will be presented. Both techniques allow rapid prototyping as well as high volume production of fully patterned substrates for a wide range of materials. This paper will present results on HE and UV-NIL, among them full wafer imprints up to 200mm with high-resolution patterns down to nm range.
