Hyunsung TNC is a technology company dedicated to the development, production, and scale-up of superconducting materials. We completed development and patent registration of a room-temperature superconductor candidate material and have grown into a superconductivity platform company.

 

Founded in 2005 as a semiconductor equipment manufacturer, we built our first decade serving the most demanding customers in electronics: process equipment development for Samsung Electronics, participation in 450mm wafer development, exclusive refurbishment of Samsung exposure equipment, and eco-friendly cable materials for Samsung mobile, alongside electronic materials and high-purity chemical development. In 2017 we turned that manufacturing discipline to superconductivity research, and built the deposition equipment for it ourselves.

 

By 2022 we had synthesized candidate materials, characterized them in house by PXRD and SQUID, and had the thing we had been working toward: a Cd-based candidate showing a superconducting transition at 37.1 °C (310 K), at ambient pressure. Reproducing that across batches and verifying it at independent laboratories has been the work ever since.

 

The theory came after the data. These measurements led Hyunsung TNC to formulate MEL (Modulated Electron Lattice) Theory, a quantitative model of high- and room-temperature superconductivity beyond the limits of conventional BCS theory. We completed its foundational patent filings in 2025; they have since entered the national phase in the United States, Europe, Japan, India and China. The theory itself is published and open to inspection as two preprints, arXiv:2512.03368 and arXiv:2601.14500.

 

AI-Driven Composition Design Platform: SuperMatics

 

MEL Theory originated at Hyunsung TNC. Built on it, SuperMatics is an AI-powered composition design platform that predicts the physical properties of high-temperature and next-generation superconductors and generates optimal material compositions.

SuperMatics integrates theory, data, AI modeling, and experimental results into a unified workflow, transforming superconductor development from serendipity-based discovery into a predictive, engineering-driven design process.

The platform is being built as a business, not a concept. SuperMatics Inc. is a U.S. company founded with backing from Hyunsung TNC; it holds the exclusive commercial license to MEL Theory and develops the software platform, the customer programs and the materials-discovery business. We hold trademark applications for the platform, work with Wilson Sonsini Goodrich & Rosati on intellectual property strategy, and partner with CAN Superconductors on R&D. More than $1 million has been raised from outside investors to date. And it does not stand alone: behind SuperMatics sit two decades of Hyunsung TNC's equipment manufacturing, a production leadership with working supply networks in Korea and Europe, and in-house synthesis, deposition and characterization - the industrial base that carries a designed composition through to a produced material. The platform will expand into an end-to-end solution, incorporating experimental data from sample fabrication and material characterization to optimize composition design, verification, and production.
