Edge SMT Files Eight Patents in a Single Day, Pushing Portfolio Past 716 Provisional Applications

Thorlabs, one of the world’s leading photonics and laser optics suppliers, opened a formal support case acknowledging Edge SMT’s equipment collaboration request for multi-wavelength laser and LED sources for the WATS photochemical CVD research platform.

Edge SMT had reached out requesting research partnership terms on the full diode laser array needed for WATS prototype operation: 365nm for molybdenum precursor activation, 405nm for MoS₂ sulfurization, 450nm for graphene deposition, and 980nm for thermal annealing. The same Thorlabs product line also includes the 532nm Raman probe laser now specified for the EdgeVerifyV2 in-situ monitoring system.

If Thorlabs engages as a full research partner, the entire visible and NIR laser stack for the WATS prototype could be sourced from a single vendor at research pricing or no cost, in exchange for paper acknowledgment and downstream sales pipeline access.

YiYun Wu, an optical engineer at ASML — the Dutch company that manufactures the only EUV lithography machines capable of producing advanced semiconductor nodes — proactively followed Edge SMT’s LinkedIn presence after reviewing the company’s public patent and technology activity.

ASML’s EUV systems cost approximately $200 million each and are required by TSMC, Samsung, and Intel to manufacture chips below 7nm. The WATS machine is designed to grow equivalent semiconductor materials without EUV lithography, photomasks, or a cleanroom environment.

The unsolicited follow from an ASML optical engineer — with specific expertise in diffractive optical elements and MATLAB simulation of optical phenomena — suggests that ASML is tracking Edge SMT’s progress. A connection request with a direct message has been initiated.

EdgeWATSOS v3, the operating system for the WATS machine, was built and tested on June 16, 2026 with a 39-of-39 passing test suite. The system reads a locked, SHA-256 hashed recipe file and executes every fabrication zone in sequence: firing laser slots, verifying material formation, sealing layers with VUV 130nm, and preventing stage advancement until each zone passes verification.

The preset library ships with ten built-in validated chemistry sequences covering graphene, C-12 diamond, MoS₂, hexagonal boron nitride, NV center qubit placement, C-13 ancilla qubit placement, and the Diaphene boundary layer. Recipe yield is tracked per preset across all runs, and the highest-yield preset is automatically selected for each zone type.

The system is designed to run on the actual WATS prototype hardware with a one-line swap from simulation to real machine drivers.

Edge SMT filed provisional patent 64/092,075 covering a real-time in-situ Raman spectroscopy verification system for the WATS machine. The system directs a 532nm probe laser through a fused silica viewport window in the WATS chamber wall and collects Raman-scattered light from the growing material surface, providing continuous spectral feedback without removing the substrate from the chamber.

The key capability: detection of the diamond phonon peak at 1332 per centimeter as it builds in real time during deposition. An operator can watch a live spectrum on a laptop screen and see the diamond peak rise with each successive deposition pass — direct confirmation that the machine is growing what the recipe says it should grow.

System cost is estimated at $3,500 to $11,000 using commercial OEM components — compared to $100,000 to $500,000+ for HHG 13.5nm EUV alternatives. Thorlabs, whose collaboration case is now open, supplies key components.

Dr. Ajith Arun Kumar, who holds an Indian provisional patent (202641035091) for a Nanochip for Molecular Detection and Sequencing based on a Menger sponge fractal geometry architecture, approached Edge SMT with a formal partnership inquiry after reviewing the company’s WATS technology.

The Menger sponge chip concept proposes using the fractal geometry’s high surface-area-to-volume ratio for improved thermal management, multi-scale signal routing, and 3D qubit arrangement in quantum processors. The design requires fabrication capabilities that conventional lithography cannot achieve at the scale the architecture demands.

WATS photochemical direct-write deposition could potentially fabricate the Menger sponge architecture at the 37-micron feature scale described in the patent from a single recipe file. Edge SMT has indicated that any fabrication partnership begins with a WATS machine license. Investment finalization status from the contact is pending.
