The Monolithic Lambda Stack™

Three integrated pillars that bypass the EUV wall and unlock the post-silicon era.

01

Lambda Process Architecture

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.

0 EUV Dependency
02

Sawyer EDA Design Suite

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.

~80% Gross Margin
03

All-Optical Switching Core

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.

4 fJ Switching

The Physics Under the Hood

Two Nobel-class phenomena — Van der Waals bonding and exciton-polariton switching — commercialised for the first time in a single manufacturable stack.

Detail A — Van der Waals Integration
CMOS Logic Layer (90nm–350nm)
Van der Waals Bond Interface
GaN-on-Si HEMT Power Layer
Additive Metallic Ink Substrate
Lattice-Free Heterogeneous Integration. Weak VdW bonds stack wildly different materials without requiring perfect atomic lattice matching — eliminating structural cracking and material strain entirely.
Detail B — Exciton-Polariton Switching
Si₃N₄ Nanocavity
MoSe₂ 2D Matrix
⚡   4 femtojoule switching threshold   ⚡

Photons couple strongly with matter inside the nanocavity, creating hybrid “half-light, half-matter” quasiparticles that switch at 100× lower energy than silicon CMOS.

Validated by UPenn & Montana State research. First commercial integration of VdW bonding + exciton-polariton switching in a single manufacturable stack.

Sawyer EDA Suite: The Unreplicable Engine

Software-grade margins on a hardware platform. No competitor can replicate the Lambda Process without licensing Sawyer.

SAWYER EDA Suite
VdW Thermal Extraction

Calculates localised heat trapping at VdW interfaces and auto-shapes metallic trace paths as micro-heat sinks.

Gate-Stack Dipole Tuning

Algorithmically balances HfO₂/Al₂O₃ oxide coatings to correct negative threshold voltage shifts automatically.

Inline Rheology Compensation

Analyses feedstock purity variance and rewrites machine toolpaths in real time to guarantee yield without hardware retuning.

Photonic Circuit Synthesis

Compiles, routes, and scales thousands of interacting optical components for all-optical AI hardware acceleration.

NEW MODULE
Deterministic Defect Mapping & Nano-Placement Compiler. Ingests real-time characterisation data of multi-material feedstocks (carbon nanotubes, MoSe₂ flakes). Maps microscopic defect zones. Automatically rewrites machine toolpaths to build circuits only on pristine, high-fidelity areas — replacing custom hardware robotics with software.
