CINOS

What CINOS does

CINOS (싸이노스, Cinos Co., Ltd.) is a Korean specialty services company founded in 2002 and headquartered in Hwaseong-si, Gyeonggi-do, that provides precision cleaning and advanced ceramic and metal protective coating for semiconductor chamber parts. Its service portfolio spans three cleaning categories—Particle Free, Damage Free, and Out-Gassing/Metallic Ion Free—delivered through proprietary processes such as PBR™, CAUS™, TIC™, and the newer SECO™ ultra-precision dry cleaning platform. The coating offering uses APS, SPS, PVD, and ALD methods with yttrium-based ceramics (Y2O3, YAG, YOF) and SiC, branded under SAC™, ZERON™, A-ZERON, HEMI™, Al ARC®, Stealth™, and MAHA™, with the new eXtreme™ line added in 2025. Quality and analytical services are delivered through the CQS/SQS quality systems and the CHEMTRACE ISO/IEC-17025-accredited lab using ICP-MS, SEM-EDS, and ATD-GC-MS.

The company's commercial model is enterprise field sales with multi-year contracts to major semiconductor fabs and equipment OEMs, including Samsung Electronics (exclusive cleaning supplier registered in Samsung's Subcontractor Association since 2020), LAM Research (qualified since 2008), TEL, AMAT, ULVAC, SEMES, ASML (registered June 2024), and TCK (2025 Best Supplier). Revenue reached 100 billion KRW in 2021, supported by a global service footprint of four Korea sites (C1–C4 in Hwaseong), two China sites (CX1, CX2 in Xi'an), and a US site (CT1 in Manor, Texas). A wholly-owned subsidiary, CINOS Engineering Solutions Inc. (established December 2023), distributes UCT Ham-let valves, fittings, hoses, and IoT-enabled flow-control products, and the parent added in-house anodizing services in January 2025. The company holds 45 technology patents, 9 design patents, ISO 9001/14001/45001/27001 certifications, AEO and AEX customs certifications, and a $3M Export Tower awarded at the 62nd Trade Day in 2025.

Broad incumbents

• CoorsTek: US-headquartered engineered ceramics manufacturer whose high-purity alumina, yttria, and other ceramic components overlap with CINOS's ceramic-coating material palette (Y2O3, YAG, YOF). Comparable in semiconductor process materials, though CoorsTek is upstream (parts manufacture) rather than a service-coating operator.
• Applied Materials: Global semiconductor equipment leader whose chamber-part business overlaps with CINOS's cleaning and ceramic recoating services. Comparable as a customer and adjacent competitor, especially across PVD, CVD, and CMP chambers.
• Entegris: US-headquartered broad supplier of specialty materials, gases, and fluid handling solutions used in semiconductor manufacturing. Overlaps with CINOS on chamber-parts protection, contamination control, and fluids management, but Entegris competes from a materials portfolio rather than a service-led coating/cleaning model.
• Tokyo Electron (TEL): Major Japanese semiconductor equipment OEM that both supplies CINOS with chamber parts and operates in-house and third-party cleaning/recoating services. Comparable in customer base and technology domain (etch, CVD, PVD); competes with CINOS where TEL prefers captive or in-sourced cleaning.
• Linde (formerly Praxair Surface Technologies): Through Praxair Surface Technologies, Linde provides thermal-spray coatings, diffusion coatings, and engineered surface services to semiconductor and industrial customers. Comparable to CINOS in APS, SPS, and CVD-style coating methodologies, but with a broader aerospace/industrial base.
• Merck KGaA (Performance Materials, ex-Versum): Through the Versum Materials acquisition, Merck supplies advanced materials and surface-modification chemistries for semiconductor manufacturing. Comparable to CINOS in deposition materials and process chemistry, though Merck operates at a much broader portfolio scale.

Regional players

• Technetics Group: US-based engineered components and surface-treatment specialist serving semiconductor and industrial-process customers with plasma-spray coatings and precision cleaning. Similar coating-process technology stack (APS, ceramic/Y2O3-class materials) to CINOS's ZERON/SAC lines.

Direct peers

• KoMiCo: Korea's largest semiconductor parts cleaning and coating specialist, serving the same Tier-1 fabs and OEMs (Samsung, SK hynix, LAM, TEL) with a comparable portfolio of precision cleaning, APS/SPS recoating, and anodizing. CINOS's principal direct head-to-head competitor in Korea and increasingly globally.
• Selen Science & Technology: Shenzhen-headquartered precision cleaning and surface-treatment specialist for semiconductor chamber parts. Competes head-to-head with CINOS for Chinese fab business and increasingly for export accounts; provides a comparable mix of particle/damage cleaning and APS ceramic recoating.

Emerging players

• Shenzhen Sinyang Semiconductor Materials: China-based emerging supplier of precision cleaning chemistries and surface-treatment services for semiconductor fabs. Comparable niche focus to CINOS on chamber-parts cleaning, with primarily regional (China) reach as opposed to CINOS's global footprint.
