Headquartered in Gumi-si, South Korea, Wonik QnC Corporation, founded in 1983 and formerly known as Wonik Quartz International Inc until 2012, is a manufacturer and supplier of critical quartz and ceramic parts for semiconductor wafer fabrication. Its business is structured into distinct divisions: Quartz Division: This segment provides a range of quartz items vital for producing semiconductor integrated circuits, as well as components for general semiconductor manufacturing, liquid crystal displays (LCDs), light-emitting diodes (LEDs), and solar cells. Ceramic Division: This division supplies a wide array of ceramic substances, including aluminum nitride, silicon carbide, boron nitride composites, silicon nitride, alumina, and zirconia. It also engineers specialized components for semiconductors, such as CVD AIN nozzles, ALD SiC susceptors, various dry etch process rings (SiC edge, capture), CVD collar rings, cover rings, moer rings, SiC DC plugs, BN composite heaters, and robotic arms. Additionally, it produces parts for Flat Panel Display (FPD) manufacturing, such as OLED EVAs, crucibles, glass lift pins and guides, supports, ceramic bearings, and other ceramic elements. The division also fabricates jigs for the automotive and electronics industries, along with equipment components for a variety of other sectors. Lamp Division: Responsible for producing EUV Lamps, these are deployed in semiconductor processing, display technology, environmental solutions, and for surface improvement applications in plastics and metal materials. Cleaning Division: Offers precision washing services, specifically for high-precision quartz components like diffusion process quartz tubes, pedestals, and Si-C boats, which are crucial for diffusion and light thin film vapor deposition processes in semiconductor fabrication equipment.
