KNJ Co., Ltd. is a company specializing in the manufacture of semiconductor components and display equipment, established in 2005. Headquartered in Asan, Chungcheongnam-do, it employs 258 people. Listed on the KOSDAQ market in 2019, it primarily produces SiC (silicon carbide) components for semiconductor processes.

"KNJ is a technology-leading company specializing in the development and manufacture of high-value-added components and equipment used in core processes of the semiconductor and display industries. Based on over 15 years of accumulated SiC coating technology, we supply CVD SiC components optimized for various semiconductor processes, creating a sustainable future."

Business Areas

• SiC Components Business for Semiconductor Processes: We manufacture consumable components such as SiC Focus Rings and SiC Rings, which are essential for semiconductor wafer etching processes, and supply them to global semiconductor device manufacturers and equipment companies. We have established an integrated production system that directly produces high-purity SiC materials using Chemical Vapor Deposition (CVD) and performs ultra-precision processing.
• Display Equipment Business: We develop and produce Edge Grinder equipment for polishing cut surfaces after the display panel cutting process, as well as panel edge inspection machines. Although we initially started with the display equipment business as our main focus, we are currently concentrating our capabilities on the semiconductor components business.
• Semiconductor Device PKG Business: We provide customer convenience services such as Si/SiC/GaN/Glass/Ceramic wafer processing and inspection services, and EDS test services. We offer compound semiconductor wafer processing, analysis, and inspection services through specialized personnel.

Products

• CVD SiC Focus Ring: It is a core consumable component that stably fixes wafers and maintains a uniform plasma distribution during the semiconductor etching process. It boasts excellent wear resistance and heat resistance in high-temperature and high-plasma environments, significantly extending the replacement cycle compared to existing silicon materials.
• Edge Grinder: This equipment polishes the cut surface after the display panel cutting process, improving the panel's durability. It also includes TFT Shorting Bar removal and free-form CNC machining functions.
• SiC Thin Film Coated Products: These are wafer processing components used in the LED manufacturing process, made by depositing a SiC thin film on processed Graphite. They have excellent durability and are optimized for various semiconductor processes.

Special Notes

• Unrivaled SiC Focus Ring Technology: We have proven our technological prowess by successfully mass-producing CVD SiC Focus Rings, the second company in the world to do so. Based on our unique core technologies, we secure a differentiated competitive advantage in related fields.
• Vertical Integration and Cost Competitiveness: We possess unique capabilities to independently design and manufacture CVD chambers, which are core equipment for SiC ring production. This significantly reduces capital expenditure (CAPEX) and completes vertical integration from material production to component processing, maintaining high operating profit margins.
• Aftermarket-Centric Business Structure: Instead of supplying to semiconductor equipment manufacturers, we have an aftermarket-centric business structure that directly supplies components to chip manufacturers such as Samsung Electronics and SK Hynix. This is a strength that provides stable supply and price competitiveness to customers, generating continuous sales.

Recruitment Information

• Main Hiring Positions: We primarily recruit for positions in Production (processing, materials), R&D (design, control), Sales, Quality Management, Operation (production management, procurement), and Administration (industrial safety management).
• Benefits: Benefits include National Pension, Employment Insurance, Industrial Accident Compensation Insurance, Health Insurance, Retirement Pension, Accident Insurance, 5-day work week, annual leave, incentive system, long-service awards, outstanding employee commendation/awards, transportation allowance for overtime/holiday work, dormitory operation, work uniform provision, various congratulatory/condolence payments and leave, in-house club operation, in-house cafeteria operation, and use of condominium memberships.
