The Step & Stamp Imprinting Lithography for Hot Embossing or UV NIL is an innovative method that has been demonstrated at the VTT Technical Research Centre of Finland.
Hot Embossing Lithography: this method consists of transferring the stamp pattern into a thermoplastic embossing material by controlling heat and pressure
UV-NIL: the Step & Cure method is using in-situ imprinting material dispensing and UV curing. This cutting-edge technology is a very promising solution for replacing standard UV-lithography systems when sub-20 nm resolution is required.
High precision micro-optical arrays and gratings
High resolution OLED displays

Other emerging techniques
Low cost production solutions of nanostructures are in development that may be the driving forces of Semiconductor, MOEMS and optoelectronics technology tomorrow. In particular, Nanoimprint lithography (NIL) and its variations have been developed as a cost-effective alternative to high-resolution e-beam lithography to print sub-20 nm geometries.
Imprinting is based on the principle of mechanically pressing thin polymer film with a stamp containing the nanopattern, in a thermo-mechanical or UV curing process. The patterned polymer can act as a final device, e.g. lense for imaging sensors, micro fluidic chip, biomedical array etc. It can also be used as a high resolution mask for subsequent steps of the process.
Imprinting is a straightforward lithography technology. There are three basic process steps:
Align the stamp with the substrate which has been pre-coated with the imprinting material
Press the stamp into the imprinting material to transfer the pattern
written on the stamp surface
Separate the stamp from the imprinting material
We can describe three imprinting or embossing techniques: Hot Embossing Lithography (HEL) using thermal plastic material, UV-NIL using a liquid resist which is then cured with UV light after molding and Soft Lithography which transfers ink previously applied to a soft stamp onto a substrate using a stamping method.
