Whether you’re working in optics, photonics, semiconductors, or academia, the Desktop R2P NanoImprinter offers a versatile, high-quality solution. Its compact footprint and user-friendly operation streamline production and make experimentation easier across departments. Wondering how this is all possible? Let’s explore the technology behind it.
Transforming the landscape of versatile Nanoimprint Lithography
Rolling Nanoimprint Lithography (RNIL), a high-volume, low-cost replication method for manufacturing functional surfaces and optical components, is at the core of our smart Desktop unit. Utilising Stensborg’s patented Optical Engine, the Desktop delivers precise UV-light intensity and optimal nanoimprinting force for high-precision imprinting.
These results are made possible through a seamless combination of our high-quality Roll-To-Plate process integrated into a compact, one-of-a-kind machine.
Our R2P system uses a patterned template against a substrate coated with UV-curable resin, enabling intricate and high-fidelity nanoimprinting. This ensures consistent, high-quality results for even the most complex nanoscale features, making it a versatile solution for small-scale production, prototyping, and rapid process development in advanced sectors.
While this cutting-edge technology offers significant advantages, we understand that fully grasping how it can benefit your specific needs is essential. That’s why we’ve compiled answers to the most common questions in the industry, helping you explore the full capabilities of the Desktop R2P NanoImprinter and how it can accelerate your NIL process development.
Desktop 101: Answering the industry’s most pressing questions about our compact Roll-to-Plate unit
1. How should we define “resolution” in nanoimprinting with the Desktop R2P?
In Nanoimprint Lithography, resolution is crucial in determining the accuracy of the final product. Beyond its replication quality, resolution depends on two key factors:
- The fidelity of the master/template
- The chemistry of the nanoimprinting resin and how it crosslinks under UV light
A resolution of down to 10nm is typically achievable with the Desktop R2P NanoImprinter. Going below that level depends on specific resin chemistry and process requirements. For more complex molecular dynamics or custom support, our team is available at https://stensborg.com/contact-us/
2. What is the Desktop R2P NanoImprinter’s imprinting speed?
Nanoimprinting speed is a vital factor when working on multiple prototype iterations or scaling-up testing for mass production. Our desktop unit offers adjustable speeds, from 0.005 m/min to 5 m/min, providing flexibility to match your project’s demands. This allows precise control during early-stage testing, ensuring both small and large-scale imprints maintain high fidelity.
3. What materials can be nanoimprinted with the Desktop?
The Desktop R2P is compatible with multiple UV-curing acrylate-based polymers, a common material choice for NIL due to its compatibility with a variety of applications. At Stensborg we develop our own in-house chemistry, empowering us with the knowledge and capabilities to provide custom solutions to your specific material needs. The machine accepts both flexible and rigid base materials as well as transparent and non-transparent. Learn more about our portfolio of consumables here.
4. What are the minimum and maximum master mould sizes compatible with the compact machine?
In Roll-to-Plate nanoimprinting, the master size is always process-dependent. As your development progresses, it’s important to anticipate shrinkage, as the active area becomes smaller—so plan accordingly!
For the Desktop R2P NanoImprinter, the maximum master mould size depends on its mounting position:
On a cylinder: up to 350mm in length and 160mm in width.
On the table: length capped at 300mm
5. Can the Desktop R2P replicate high-aspect-ratio microstructures with high fidelity?
Yes, the Desktop R2P can handle high-aspect-ratio (HAR) nanostructures. The specific results will always depend on the material, durability, and structure size. For example, clients report successful replications of aspect ratios 3:1, such as a structure with 5µm height, 1.5µm width, and 1.25µm gap. However, testing is recommended for specific applications to ensure optimal results.
6. What is the smallest nanostructure you can replicate?
Our unique optical engine technology integrated in the smart machine allows us to achieve high precision in nanostructure replication, as low as 10nm in width and depth. This level of accuracy makes the roll-to-plate unit ideal for applications in semiconductor development, microfluidics, biosensing, and photonics.
7. What Is the maximum nanoimprinting size with the Desktop R2P?
The standard maximum nanoimprinting size for the Desktop is 105mm x 188mm, and larger custom solutions are also available. We have delivered, bespoke machines with dimensions of 330mm x 600mm to accommodate larger projects. For more details on the technical specifications of our Desktop R2P NanoImprinter, download the brochure below.
8. What type of substrates can be used in the nanoimprinting process?
The Desktop R2P NanoImprinter is substrate-independent. It can nanoimprint on a variety of materials, flexible or rigid and both transparent and non-transparent Examples include foils, wafers, glass plates, microscope slides, and others.
9. How does the Roll-to-Plate Desktop handle throughput, and how does it compare to industry standards?
The Desktop R2P’s advanced Optical Engine enables rapid, high-efficiency nanoimprinting, often surpassing industry standards thanks to its continuous rolling process. With an actual nanoimprinting speed of up to 5 meters per minute, the system stands out in throughput and precision. While resin application (“inking”) and handling may add time, proper automation can streamline these steps, seamlessly integrating large-scale industry setups.
