Technology & Products
Key Products
Semiconductor process components including process chambers and showerheads (gas distribution); heaters; precision micro-hole drilling; special joining (FSW, E-beam, brazing, TIG, laser); heat treatment; dry/wet polishing; soft & hard anodizing; precision cleaning (chemical polishing, DI water, ultrasonic); cleanroom assembly (Class 100-10,000); CMM inspection; Rapid Prototype Solution (RPS) 24-hour prototyping; metal 3D-printed aerospace parts with integrated post-processing.
Technological Advantage
End-to-end in-house production chain from raw material to cleanroom assembly; proprietary ultra-precision micro-hole drilling; integrated post-processing of additively manufactured metal parts; process-by-process inspection and production traceability; InnoBiz and venture-company certifications.
Differentiation
Value Proposition
A fully integrated "One-Stop Solution" that keeps design, raw material, machining, welding/joining, heat treatment, polishing, anodizing, cleaning and cleanroom assembly in-house, reducing handoff risk, shortening lead times and delivering consistent quality for complex, hard-to-machine semiconductor and aerospace components.
How They Differentiate
Differentiates through a single-site, fully integrated production structure (material supply through cleanroom assembly and inspection) rather than discrete machining only, plus semiconductor-grade cleanliness and traceability discipline applied to metal AM post-processing.
Market & Competition
Target Customers
Semiconductor equipment OEMs (global and domestic), display and medical device equipment makers, and emerging aerospace/defense primes and MRO providers.
Industry Verticals
Semiconductor equipment; display; medical devices; aerospace and defense (emerging); custom precision manufacturing.
Competitors
Domestic and international semiconductor equipment component suppliers such as HS Hi-Tech (Korea), and other precision-machining/parts makers serving Lam Research, Applied Materials and Korean OEMs; in metal AM aerospace, established AM service providers and OEM-qualified suppliers.
Growth & Milestones
Growth Metrics
2025 consolidated revenue ₩92.3B (~$67M) with operating profit ₩7.6B, up roughly sevenfold year-on-year; equity ~₩27.5B; ~290-338 employees; pursuing KOSDAQ IPO (927,328 shares planned, ~21.8% offered) led by Samsung Securities.
Major Milestones
Founded 1997; EOS metal 3D printing MOU (Dec 2022); completed Korean Air supplier registration; submitted KOSDAQ preliminary listing review application (Aug 6, 2026); cleared KOSDAQ listing review in record 26 business days (Sept 14, 2026); exhibiting semiconductor-grade precision machining and metal 3D-printed aerospace components at AEROTEC 2026 (Sept 30-Oct 2, Changwon).
Notable Customers
Lam Research; Applied Materials; four of Korea's top-10 semiconductor equipment makers by revenue.
