The Future of Microfabrication Is Transparent—And It's Made of Glass

Imagine designing and manufacturing complex 3D microdevices—not on the surface of a material, but within it. Picture this microengineering feat happening inside solid glass, with no masks, no alignment errors, and no assembly headaches.

At FEMTOPRINT, this isn't science fiction. It's our everyday reality.

A Paradigm Shift in Microfabrication

Traditional microfabrication often comes with trade-offs: multi-step mask-based processes, cleanroom constraints, and the ever-present challenge of component alignment. FEMTOPRINT disrupts this paradigm with ultrafast laser micromachining, a maskless, monolithic, and wafer-level approach that delivers unmatched structural precision inside transparent substrates.

Our Selective Laser Etching (SLE) technology allows us to carve complex, functional microstructures directly into the bulk of various glass families—fused silica, borosilicate, fused quartz, ULE®, and more—without compromising mechanical integrity or optical transparency.

Engineered for Scale, Designed for Complexity

For CTOs driving innovation at scale, flexibility and reproducibility are mission-critical. That’s why we offer:

• Contract Development: From concept to functional design, with toolpath optimization and microstructure validation.
• Contract Manufacturing: Scalable, high-throughput production—supporting thousands of wafers per year, compatible with MEMS foundry standards.
• Rapid Prototyping: Accelerated iteration without the overhead of masks or cleanrooms.

With micrometer-level tolerances, surface roughness down to Sa ≤ 10 nm, and aspect ratios above 1:500, we meet the stringent requirements of next-generation applications—from lab-on-a-chip systems to fiber-optic connectors, 3D glass ion traps, and surgical microdevices.

Why Glass? Because Performance Demands It

Glass is not only biocompatible and hermetic, it’s also transparent to both optical and RF wavelengths, chemically inert, and thermally stable. These properties make it the ideal substrate for cutting-edge technologies in:

• Medical Devices – integrated microfluidics, hermetic packaging, surgical microsystems.
• Integrated Photonics – waveguides, fiber ferrules, micro-optical assemblies.
• Quantum Technologies – ion traps, vapor cells, through-glass vias.
• Biotechnology – nozzles, print heads, analytical chips.
• Luxury Watchmaking – complex bridges, dials, hands, and 3D masters with micron-level fidelity.

Partnering for Innovation

Our clients choose FEMTOPRINT because we deliver more than parts—we deliver innovation. With robust IP, scalable infrastructure, and deep expertise across micro-optics, microfluidics, and micro-mechanics, we support CTOs in de-risking development and accelerating time to market.

In a world where miniaturization, integration, and precision define success, transparent glass microfabrication is no longer a futuristic idea. It’s a transformative capability—and it’s here now.
