Sovereign Semiconductor Infrastructure:
Capital-Light, High-Yield 3D Heterogeneous
Chips Engineered by Software.
Three integrated pillars that bypass the EUV wall and unlock the post-silicon era.
Capital-light additive packaging that vertically folds mature 90nm CMOS digital logic directly over high-performance GaN/SiC wide-bandgap power devices. No EUV required. 100% domestic supply chain.
Proprietary multi-physics compiler that natively models Van der Waals interfaces, GaN-on-Si RF structures, and photonic nanocavities. The design tool Cadence and Synopsys architecturally cannot build.
MoSe₂ 2D semiconductor matrices inside Si₃N₄ photonic nanocavities create exciton-polariton quasiparticles — achieving non-linear optical switching at a historic 4 femtojoule energy threshold. 100× more efficient than silicon CMOS.
Two Nobel-class phenomena — Van der Waals bonding and exciton-polariton switching — commercialised for the first time in a single manufacturable stack.
Photons couple strongly with matter inside the nanocavity, creating hybrid “half-light, half-matter” quasiparticles that switch at 100× lower energy than silicon CMOS.
Software-grade margins on a hardware platform. No competitor can replicate the Lambda Process without licensing Sawyer.
Calculates localised heat trapping at VdW interfaces and auto-shapes metallic trace paths as micro-heat sinks.
Algorithmically balances HfO₂/Al₂O₃ oxide coatings to correct negative threshold voltage shifts automatically.
Analyses feedstock purity variance and rewrites machine toolpaths in real time to guarantee yield without hardware retuning.
Compiles, routes, and scales thousands of interacting optical components for all-optical AI hardware acceleration.
Three phases from validated prototype to all-optical AI compute platform — precisely aligned with the IMEC global logic scaling roadmap.
From a defensible beachhead to the AI compute infrastructure of the next decade.
Defense, aerospace, and grid-edge AI power routing. High-temperature, high-reliability chips for customers who pay NRE fees and have zero tolerance for supply chain disruption.
Next-generation GaN/SiC power modules for EV inverters, ultra-fast charging stations, and industrial power conversion — actively seeking 3D logic integration solutions.
Post-silicon all-optical AI accelerators and high-density heterogeneous compute architectures. The Photonic Circuit Synthesis Plug-In is the entry point to this market.
Deep hardware-software co-design expertise spanning sovereign defense, advanced EDA, and next-generation packaging.
Deep experience in hardware-software co-design, multi-physics compiler orchestration, and next-generation heterogeneous packaging architectures.
Head of design workspace layout, PDK workflow optimisation, and front-end CAD interface deployment for the Sawyer EDA interactive dashboard.
