NILT Nanoimprint Masters (also known as molds or stamps) are engineered to deliver exceptional nanoscale pattern fidelity across a wide range of nanoimprint lithography processes. With years of experience in advanced lithography and nanofabrication, we create masters that combine ultra-fine pattern accuracy with long-term stability ideal for R&D, pilot production, or high-volume replication.
Advanced nanostructure fabrication
Masters are created using high-end lithography and precision etching to achieve clear, sharp, and highly uniform nanoscale patterns.
Multiple master formats
Choose between wafer-based masters or custom-shaped formats that integrate seamlessly into your imprinting setup or production tools.
Wide material selection
Masters are available in materials such as silicon and quartz, selected for optical performance, durability, or etching depth based on your needs.
Fully custom patterning
From micro-optics and meta-surfaces to diffractive gratings and complex 3D shapes, each master can be customized to match your design requirements.
High surface quality
Every master undergoes careful processing and inspection to ensure low surface roughness, high pattern consistency, and repeatable imprint performance.
Seamless process support
Beyond fabrication, NILT provides assistance with imprinting, replication, and scaling — ensuring the master performs exactly as intended.
NILT Nanoimprint Masters are ideal for:
Meta-optics and meta-lens fabrication
Diffractive optical elements and gratings
Micro-optical components and micro-lens arrays
MEMS and microfluidic device structures
Wafer-level optics and flat optical components
Roll-to-roll replication, embossing, injection molding, and other high-volume processes
