Simplifying Metal Oxides Deposition™
Revolutionary Formulations
Phosio is developing UV-curable metal oxide precursors, allowing deposition at ultra-low temperatures (as low as 150°C), a significant improvement over sol-gel methods. PhosioLux® products are compatible with various solution-based deposition techniques such as spin coating, slot die coating, and inkjet printing, enabling rapid deposition at a lower cost compared to vapor deposition methods. PhosioLux® products can be patterned with direct UV exposure using UV, DUV and EUV. This platform technology finds applications in semiconductors, displays, solar cells, batteries, sensors, LEDs, memory devices, supercapacitors, neuromorphic chips, biomedical implants, IoT devices, and optical coatings.
The Market Need
As AI, cloud computing, and next-generation devices accelerate, there's growing demand for faster and more efficient photonic technologies. From data centers to wearable displays, industries rely on high-performance optical components to keep up with innovation.
A key building block is the optical grating, used to guide and control light in silicon photonics, sensors, telecom systems, and AI-powered smart glasses. However, current fabrication methods struggle to deliver the performance, scale, and affordability required for broad adoption.
Meta’s Orion smart glasses highlight both the potential and the problem. Creating their lightweight, immersive AR displays is technically feasible today, but only through costly, high-temperature, multi-step processes. These methods deliver performance, but they aren't scalable or cost-effective for consumer markets.
Materials like polymers lack the needed optical index and durability, while sol-gels and vacuum-deposited systems require expensive equipment and are limited in throughput. Across the board, today’s solutions force a trade-off between performance and manufacturability.
Solving this bottleneck, making high-index, high-quality optical gratings at scale is critical for unlocking the future of AI-powered photonics, from cloud infrastructure to everyday wearables.
The Solution
Phosio solves the long-standing challenges of slow, costly, and inefficient metal oxide film fabrication. Traditional methods like Atomic Layer Deposition (ALD) are high quality but extremely slow and expensive, while sol-gel approaches often produce low-density films that require multiple extra steps. Phosio’s breakthrough is a fast, cost-effective solution-based process that delivers high-density, uniform metal oxide films (30× faster and at up to 90% lower cost than conventional techniques). Our materials are compatible with low-temperature processing, making them ideal for flexible plastic substrates. Finally, they can be directly patterned using standard lithography methods, eliminating the need for additional etching or masking steps.
With Phosio, manufacturers can streamline production and unlock next-generation semiconductor and photonics applications at scale. With low-temperature processing (<100 °C), exceptional surface smoothness (<0.5 nm RMS), and refractive indices up to 2.30, Phosio enables next-generation optical components to be manufactured faster, cheaper, and at scale, without compromising performance.
Enabling Hardware for AI
Smart glasses are expected to be the next major technology platform, just like smartphones were 15 years ago. They will let people interact with artificial intelligence (AI) and digital content in real time, hands-free, and without looking down at a screen. As AI becomes a bigger part of everyday life, smart glasses will be the most natural and powerful way to connect people with technology. Phosio is helping make this future possible.
Our patented materials are used in the tiny display systems inside smart glasses. These advanced coatings have tunable refractive indices (n = 1.20 to 2.60) and deliver crystal-clear optical quality across the full visible spectrum, without yellowing or haze. This means brighter images, wider fields of view, and better overall performance, while also allowing glasses to be smaller, lighter, and more comfortable to wear.
Phosio solves one of the hardest problems in AR hardware: how to deliver high-quality visuals in a compact form factor. As smart glasses move closer to mass-market adoption, Phosio’s technology gives manufacturers the performance they need and the scalability to build for hundreds of millions.
