Nanoimprint Lithography
NIL - EV Group
EVG is the market-leading supplier of nanoimprint lithography (NIL) equipment and integration processes. EVG pioneered and mastered NIL from a research approach more than 15 years ago, to implementation in volume production on various substrate sizes from 2 inch compound semiconductor wafers to 300 mm wafers and even on large-area panels. NIL is the most promising and cost-effective process for generating nanometer-scale-resolution patterns for a variety of commercial applications in bioMEMS, microfluidics, electronics and, most recently, various diffractive optical elements.

UV-NIL / SmartNIL® Systems
-
EV Group provides a complete product line for UV-based nanoimprint lithography (UV-NIL), including different single-step imprinting systems, large-area imprinters as well as step-and-repeat systems for efficient master fabrication. Besides soft UV-NIL, EVG offers its proprietary SmartNIL technology with multiple-use polymer stamp technology. The efficient and robust SmartNIL process provides high pattern fidelity, highly uniform patterned layers and minimum residual layers, combined with easy scalability in wafer size and production volume. EVG´s SmartNIL redeems the long-term promise of nanoimprinting being a high-performance, low-cost and volume-capable manufacturing technology for mass production of micro- and nanoscale structures.

Hot Embossing Systems
-
EV Group’s series of high-precision hot embossing systems are based on the company’s market-leading wafer bonding technology. Excellent pressure and temperature control as well as uniformity over large areas allow for high accuracy imprints. Hot embossing is a cost-effective and flexible fabrication technology with very high replication accuracy for feature sizes down to 50 nm. The systems are well suited for embossing complex micro- and nanostructures and high-aspect ratio features into a wide range of polymer substrates or spin-on-polymers. The combination with stamp-to-substrate alignment allows alignment of hot embossing to pre-processed substrate structures.
