La Luce Cristallina launches CMOS-compatible oxide pseudo-substrate
La Luce Cristallina of Austin, TX, USA – which manufactures silicon-integrated high-performance materials for silicon photonics, focused on barium titanate (BaTiO3) materials – has launched its new CMOS-compatible oxide pseudo-substrate, enabling high-quality, epitaxial strontium titanate (SrTiO3) films to be grown directly on 200mm silicon and silicon-on-insulator (SOI) wafers. This platform bridges the gap between academic oxide research and commercial manufacturing, facilitating the development of advanced oxide devices using standard semiconductor tools. The solution supports superconducting RF electronics, ultra-low-loss RF components, single-photon detectors, quantum sensing, advanced computing architectures and other emerging applications aligned with silicon photonics and heterogeneous integration.
Researchers often rely on small, costly single-crystal SrTiO3 substrates that are incompatible with standard fabrication facility workflows. La Luce Cristallina says that its pseudo-substrate platform eliminates these bottlenecks by aligning with foundry-driven roadmaps for heterogeneous integration, co-packaged optics, wafer-level prototyping and next-generation photonics, enabling manufacturing scalability. The solution delivers large-area wafers, high-quality epitaxial films (with thicknesses ranging from 4nm to 50nm) and standard CMOS tool compatibility.
“Our new CMOS-compatible oxide pseudo-substrate brings high-performance oxide electronics out of the lab and onto industry-standard silicon wafers, unlocking scalable devices for RF components and quantum applications,” says chief technology officer & co-founder Agham Posadas. “By improving cost and scalability while eliminating CMOS tooling incompatibilities, we can help customers across the silicon photonics ecosystem accelerate innovation.”
La Luce Cristallina says that its wafer-scale approach significantly expands usable area while maintaining film quality, supporting numerous applications across diverse, growing markets. The RF components market is forecasted to grow from $50bn to $91.19bn by 2030, bolstered by the defense and sensing sectors, 5G deployments and satellite communications. Amid strong government funding, the quantum technologies market (including sensing, detection and superconducting electronics) is projected to grow at a compound annual growth rate (CAGR) of 41.8% to $20.2bn by 2030.
The platform can support oxide electronics research for universities, national laboratories and commercial R&D teams that were previously constrained by substrate availability. La Luce Cristallina currently serves customers across integrated photonics research, quantum computing and other advanced electronics sectors.
“La Luce Cristallina’s CMOS-compatible oxide pseudo-substrate removes one of the biggest barriers to scaling oxide electronics,” comments Ron Kelly, CEO of Ambature Inc. “By enabling high-quality strontium titanate films on 200mm silicon wafers using standard semiconductor tools, La Luce Cristallina is helping companies like Ambature move advanced RF and quantum technologies from research environments toward real-world systems.”
