A PM that I work with found an article on Diamond Quanta's commercialization approach in the emerging diamond semiconductor industry. Below, I synthesize the article with the recent $SOTK / Diamond Quanta collaboration announcement. In a January 19, 2026, feature for Power Electronics News, interim editor-in-chief Aalyia Shaukat surveyed the emerging diamond semiconductor industry and its potential to push beyond today's wide-bandgap (WBG) materials. The article situates diamond among a new class of ultra-wide bandgap (UWBG) semiconductors whose bandgap exceeds 4 eV, offering theoretical advantages over both GaN and SiC in thermal conductivity, critical electric field strength, and high-temperature operation. While GaN-on-Si is scaling toward 300 mm wafers and SiC dominates at voltages up to 3.3 kV, diamond remains largely in the R&D phase, with the industry still working to reliably produce 4-inch single-crystal wafers, the threshold widely seen as necessary for mass production. Shaukat profiles the growth techniques of the major players, ranging from mosaic homoepitaxy to heteroepitaxial step-flow processes. The piece then focuses on Diamond Quanta, founded in 2024 by Adam Khan (previously of Akhan Semiconductor), which takes a different approach entirely: growing polycrystalline diamond on silicon at low temperatures compatible with standard CMOS processing. In an interview at CES 2026, Khan described how the company's partnership with Japan's ExtenD Corporation and equipment integration by Heller Industries enabled the production of 300 mm diamond-on-silicon wafers, and how a laser densification process developed with Lawrence Livermore National Labs smooths the rough diamond surface for direct bonding. Diamond Quanta's near-term launch product is Adamantine Optics, a scratch-resistant diamond glass for AR displays and smartphones, while thermal interface materials and diamond interposers represent the next commercial steps. Active-doped diamond power devices, which Khan says have already demonstrated stable PIN diode operation from 400 °C to 600 °C, well beyond SiC's performance dropoff, are targeted for commercialization by 2030. This trajectory gained further momentum in March 2026 when $SOTK announced a technical collaboration with Diamond Quanta to integrate its precision ultrasonic coating technology into Diamond Quanta's manufacturing workflow, supporting repeatable thin-film deposition and multilayer integration across engineered diamond applications. The partnership is significant because it aims to strengthen process repeatability, film uniformity, and manufacturability as Diamond Quanta advances its materials platform toward OEM qualification and scalable manufacturing environments. In practical terms, the approach aligns with Diamond Quanta's broader strategy of commercializing defined process modules rather than raw materials, reinforcing its IP-led, fab-light model as it works toward OEM qualification and strategic manufacturing partnerships. For Sono-Tek, the collaboration extends its ultrasonic coating expertise into a high-growth advanced materials segment; for Diamond Quanta, it adds a proven precision deposition capability to its standardized process architecture, another concrete step toward making engineered diamond manufacturing compatible with existing semiconductor toolchains and, ultimately, toward Khan's stated goal of making diamond as accessible as silicon. #QuantumComputing #CHIPSAct #SOTK #AdvancedManufacturing #Semiconductors #SmallCaps #DiamondSemiconductor #DeepTech #QuantumTechnology
