Ntrium

Based in Gyeonggi, South Korea, Ntrium Inc. , doing business as Ntrium was founded in 2013 by CEO Jung Se-young, a former Samsung Electronics semiconductor researcher. The company was established as the first spin-off under the researcher entrepreneurship program of the Advanced Institutes of Convergence Technology. Since its founding, Entrium has focused on nano- and micro-particle synthesis, surface treatment technologies, conductive powder development, and advanced materials for semiconductors and electronics.

Over time, the company expanded into automotive electronics, EV battery materials, and thermal management solutions. The company's most recent completed funding round was a KRW 3 billion investment received in March 2019 from Capstone Partners and Korea Venture Investment. The company focuses on developing and manufacturing advanced functional materials for semiconductor, electronics, automotive, and battery applications. Its product portfolio includes EMI Shielding Material Solutions, Thermal Interface Materials (TIM) for EV batteries and AI/5G semiconductors, conductive powders, conductive films, and nano-material-based electronic materials.

Entrium's technologies are designed to improve electromagnetic interference protection, heat dissipation, electronic performance, and manufacturing efficiency for customers in the semiconductor and electronics supply chain. The company also develops specialized coating and particle-engineering technologies that support next-generation semiconductor packaging and automotive electronics applications. The company's revenue is generated through the manufacture and sale of semiconductor materials, EMI shielding materials, conductive powders, thermal management materials, and related advanced electronic materials supplied to customers in the semiconductor, electronics, automotive, and battery industries. Revenue growth has been supported by expanding commercialization of its material technologies and increasing adoption within semiconductor and industrial applications.

The company reported revenue of approximately KRW 4. 8 billion in the most recent year disclosed in the article, reflecting significant growth from the prior year. Following its most recent completed funding round in 2019, Entrium planned to use the proceeds to enhance its EMI shielding material technology, purchase raw materials and production equipment, and accelerate R&D activities for the localization and commercialization of advanced industrial materials. The company also aimed to expand the application of its material technologies beyond smartphones and semiconductors into automotive electronics and other high-value industrial sectors.
