Technologies
SILSEF’s key technology is Nano Imprint Lithography (NIL) invented in 1995 in the U.S, to reduce the size of microelectronic circuits. It is ranked among the revolutionary technologies by the MIT (“Ten Technologies That can change the world”), thanks to its generic scope and large variety of potential applications.
Schematically, a polymer deposited on the surface of the material, is embossed with a nano-structured stamp. Then the pattern is transferred into the material using the deformed polymer as a disposable etching mask.
In the traditionnal photo lithography process the resist mask is processed by photo insulation through mask. There are limitations related to light interaction with the sides of the masks for nanoscale patterns. Using NIL the resist will be processed by plastic deformation using a hard or soft stamp.
SILSEF develops processes, materials and micro nano patterns to meet its client’s requirements. Along the years, SILSEF turned various solutions to be able to bring patterning on any material. We are able to pattern large surfaces (10sx10s of cm) on flat but also on 2.5D (half sphere).
SILSEF is active on the whole process flow, from the design of functional partterns (for optics or wettability) down to control process through dedicated and internally designed characterization equipments to meet your application :
- Design of patterns including simulation and modelling
- Manufacture of tools at micro and nanoscale
- Transfer patterns on a range of materials by etching plastic deformation molding or contact printing
- Geometric and functional characterizations such as wetting proporties or diffraction effects

Nanopatterning via Plastic Injection: Revolutionizing Surface Engineering with SILSEF’s Patent
Introduction
In industries such as optics, photonics, and microelectronics, surface engineering is critical for achieving superior performance, efficiency, and functionality. Nanopatterning—the creation of precise nanoscale features on surfaces—has become a transformative technology, enabling breakthroughs in light manipulation, anti-reflective coatings, and material durability.
At SILSEF, we have developed a groundbreaking approach to nanopatterning via plastic injection molding, protected by our proprietary patent. This innovative method merges the precision of nanoscale engineering with the scalability and cost-efficiency of plastic injection, opening new avenues for industries such as optics, photonics, biomedical devices, and consumer electronics.
Why Nanopatterning Matters
Nanopatterned surfaces offer unique advantages that traditional smooth or micro-patterned surfaces cannot achieve:
Superior Optical Performance: Nanopatterns manipulate light at the sub-wavelength scale, reducing reflections, enhancing transmission, and enabling advanced functionalities like anti-glare coatings, light trapping in solar cells, and high-efficiency sensors.
Enhanced Material Properties: Nanoscale features improve mechanical properties, such as wear resistance, hydrophobicity, and adhesion, making surfaces more durable and functional.
Precision and Customization: Nanopatterning allows for the creation of highly specific designs tailored to applications, from plasmonic sensors to photonic crystals.
