What YMC does

YMC Co., Ltd. (와이엠씨) is a Korean specialty manufacturer founded in February 2008 and listed on KOSDAQ since 2012, supplying process-critical components, materials, and surface treatment services to semiconductor and display equipment makers and their end-user fabs. Its core product lines span four areas: (1) surface treatment services including anodizing (sulfuric, mixed, and oxalic acid types), thermal spray coating (Al2O3, Y2O3, YAG), and ultrasonic cleaning for vacuum chamber parts; (2) precision machining including super-precision MCT micro-hole work and abrasive blasting/grinding for parts up to 8.6G display size; (3) sputtering targets (Cu, Ti, Mo, Ag, Al, Ta) plus backing plate bonding — including Korea's first localized backing plate-target assembly unit/water cooler; and (4) ceramic and silicon carbide (CVD SiC) components with proprietary refurbishment technology used in semiconductor etch process rings and cathodes. The company also operates an in-house R&D center covering parts technology, simulation-based design, and future display materials.

YMC monetizes primarily through direct B2B enterprise sales of components and materials on negotiated per-contract terms, complemented by recurring surface treatment, refurbishment, and (since 2024–2025) equipment preventive maintenance and robot overhaul services. Customers are concentrated among leading Korean semiconductor and display manufacturers — including a long-running subcontractor relationship with "Company S" (a major Korean semiconductor firm) and a Samsung Display ecosystem link visible from the corporate website. Distribution is handled through a dedicated marketing team organized by product line (Display Parts, Display Materials) plus a Management Planning team handling IR and finance. YMC has three production/operating locations — Asan-si headquarters, the newly built WYCOM Dangjin factory (2024), and WYCOM — plus a strategic Pangyo 2nd Techno Valley office opened in 2024, with wholly-owned subsidiaries YCOMM, Leotec, and YMS (formed 2025) supporting the equipment maintenance line.

Operationally, the company is in a profit compression phase: consolidated sales moved from 240.9 billion KRW (2021) to 167.1 billion KRW (2022), recovered to 204.6 billion KRW (2023), then declined to 167.7 billion KRW (2024) and 172.8 billion KRW (2025), while operating profit collapsed from 15.8 billion KRW (2023) to 6.9 billion KRW (2024) and 4.6 billion KRW (2025), and net profit fell from 14.8 billion KRW (2023) to 1.1 billion KRW (2025). To counter this, YMC is pivoting toward higher-value semiconductor SiC components, advanced packaging-enabling technologies (via the Samba Solutions investment targeting HBM/TSV dry etching), and recurring service revenue through PM and robot overhaul contracts.

Core offering

YMC manufactures and supplies core components and materials for semiconductor and display manufacturing equipment. Its portfolio covers four main lines: (1) surface treatment services such as anodizing, thermal spray coating, and ultrasonic cleaning for vacuum chamber parts; (2) precision machining of super-precision parts up to 11G thickness; (3) sputtering targets and backing plates made of Cu, Ti, Mo, Ag, Al, and Ta; and (4) ceramic and silicon carbide (SiC) parts including CVD SiC-coated rings and cathodes. It also provides equipment preventive maintenance (PM) and refurbishment services.

Product overview

YMC is a global leader specialized in electronic device manufacturing components and materials, particularly for semiconductor and display industries. The company operates a multi-product portfolio consisting of four core service/product lines: (1) Surface Treatment Services including Anodizing, Thermal Spray, and Ultrasonic cleaning for vacuum equipment parts; (2) Precision Machining Services offering super precision MCT machining, abrasive blasting, and grinding for parts up to 8.6G size; (3) Target Products including sputtering targets (Cu, Ti, Mo, Ag, Al, Ta materials in flat and rotary types) and backing plates with bonding technology; and (4) Ceramic and Silicon Carbide Products featuring CVD SiC coatings, precision machined ceramic parts, and SiC refurbishment technology. Additionally, YMC operates an R&D Center focused on parts technology, design technology, and future display technology development, and provides Equipment PM (preventive maintenance) services. The company serves both semiconductor and display manufacturers with parts and services that contribute to particle reduction, process stability, product lifetime extension, and yield improvement.
