By Smart Material Solutions, Inc.
We offer a variety of nanopatterned and micropatterned molds for roll-to-roll (R2R) and plate-to-plate (P2P) UV nanoimprint lithography (UV NIL), thermal embossing, extrusion, and photolithography. The molds are fabricated with SMS's patented nanocoining process, which is unique in its ability to seamlessly pattern cylindrical molds for R2R processes hundreds of times faster than electron-beam lithography. Contact us if you would like more information or to discuss custom development. Mold Specs Materials: High-phosphorous nickel, copper, and aluminum. Seamless cylindrical photomasks are metal-coated glass or quartz. Dimensions: Up to 6.5 inches in diameter and 6.5 inches long. Larger dimensions possible with equipment upgrade. Form Factors: Flexible shims, seamless cylindrical drums, seamless cylindrical sleeves, and seamless cylindrical photomasks. Feature Specs Pitch: 200 nm to 8 microns demonstrated. Larger and smaller pitches possible with development. Aspect Ratio: Up to about 0.7 (height:pitch). Lattices: Square, hexagonal, and stochastic. Shapes: Bumps, pillars, microlenses, pyramids, hierarchical features (nanofeatures on top of microfeatures), and more. SEM images of diamond dies and polymer replicas of our molds are shown below (molds will have inverted gender from SEM images).
