Youngshin Quartz Co., Ltd. is a company specializing in the processing of quartz glass for semiconductor manufacturing, established in 1985. It is a wholly foreign-invested enterprise formed as a joint venture between Germany's Heraeus Quarzglas and Japan's Shin-Etsu Quartz, headquartered in Jincheon, North Chungcheong Province. The company produces and supplies high-quality quartz glass products essential for semiconductors, flat panel displays, optical fibers, and more.

Youngshin Quartz is a leading supplier of high-quality quartz glass products for the semiconductor industry. We provide innovative and customized solutions to supply our clients with superior quality quartzware in a timely manner. As a joint venture between Germany's Heraeus and Japan's Shin-Etsu Quartz Products, we operate a manufacturing plant in Chungbuk and are integrated into the global Heraeus and Shin-Etsu Quartz networks.

Business sectors

• Quartz Glass Processing for Semiconductor Manufacturing: We process and supply high-quality quartz glass products essential for miniaturization processes in semiconductor manufacturing, such as ALD, LPCVD, and Diffusion. These products play a critical role in wafer protection and the fabrication of high-quality thin films.
• Production of Quartz Glass for Displays and Optical Fibers: We produce high-purity quartz glass products essential for the manufacturing of flat panel displays and optical fibers. In the OLED/LED sector, we provide quartz glass for sublimation purification and MOCVD-related products.
• Quartz Glass for Solar and Optical Fields: We produce quartz glass for solar cells and Si-Ingot Growers, and also handle optical products such as Fused Silica for general and high-tech applications. We also supply quartz tubes for UV lamps and Excimer lamps.

Products

• Quartz Ware for Semiconductor Manufacturing: High-purity quartz components optimized for ALD, LPCVD, Diffusion, and Etching processes, contributing to improved process stability and yield.
• Quartz Tube: A product required for the semiconductor thin film deposition process, capable of production with a maximum outer diameter of 900mm and a length of up to 2000mm. We possess the first in Korea to have in-house tube production technology using cylinders as the base material.
• Quartz Boat & Pedestal: High-quality quartz products used to support and transport wafers in semiconductor processes. Equipped with a slotting machine for solar cells, it is possible to produce fine boat slots.

Special Features

• Global Joint Venture and Technological Capabilities: As a 100% foreign-invested company with technology and capital invested by Germany's Heraeus Quarzglas and Japan's Shin-Etsu Quartz, we are growing based on our global network and accumulated quartz glass production technology.
• Supplying Key Customers in the Semiconductor Industry: We stably supply quartz glass for semiconductor manufacturing to major customers such as SK Hynix and Samsung Electronics, contributing to the resolution of the global semiconductor supply shortage.
• Innovative Technology Localization and Certification: We have developed innovative technologies and obtained numerous quality certifications, including the localization of Special Surface Treatment (SST) technology, securing the first domestic capability to cut 1.5m quartz plates, and the first domestic production of cylinder-based tubes.

Job Information

• Major Recruitment Positions: Primarily hiring for QC team staff (product inspection), production team staff, and facilities/maintenance team employees; semiconductor engineer and quality manager roles are also included.
• Benefits: We provide health checkups, support for various family events, group accident insurance, support for business and communication expenses, tuition support for children, retirement pensions, incentive systems, awards for long-term service and outstanding employees, and the four major insurances. We also have a variety of welfare systems in place, including an on-site cafeteria (providing lunch, dinner, and breakfast), in-house clubs, and an employee association (for family events).
