What SEMICS does

SEMICS Inc. is a privately held Korean semiconductor wafer prober and inspection equipment manufacturer founded in 2000 and headquartered in Gwangju-si, Gyeonggi-do, South Korea. The company designs and produces wafer probers used in electrical die sorting (EDS) and wafer-level chip testing, serving global semiconductor manufacturers — including integrated device manufacturers (IDMs), fabless semiconductor firms, and semiconductor foundries — through direct enterprise sales and regional channel partners.

The company's product portfolio is anchored on three named prober platforms: OPERA, a premium group prober composed of multiple real probers arranged side-by-side and in-row, delivering 800kgf probing force per cell, a compact card changer module, an anti-vibration mechanism, the fastest wafer handling loader, and smart wafer pre-aligner and buffer systems; OPUS5, a standard model that handles both 12-inch SEMI standard wafers and 297mm wafers without a change kit, optimized for compact footprint, high accuracy, and fast wafer handling for top-loader automation; and OPERETTA, a premium wafer probing system with infinite side-by-side cell expansion. SEMICS has continuously iterated the OPUS3 family (variants ST, SD, SE, SH, SP, HD, DP, SLT, FD8, FD12 for 6/8/12-inch wafer sizes) and introduced OSTINATO as a new 2024 platform. Certifications span ISO 9001, ISO 14001, ISO 45001, ISO 22301, ISO 37301, Semi S2/S8, CE, and CSA, alongside Korean government designations including World-Class Product (2016, 2018, 2019), World-Class 300 (2018, 2022), and the Gold Tower Industrial Medal awarded to Co-CEO Yu Wan-sik in December 2025.

SEMICS operates a direct enterprise sales model supplemented by regional channel partners. Direct offices span Korea (headquarters plus R&D in Seongnam-si and Factory 2 in Gwangju-si), China (Shanghai, Wuhan, plus the Hefei manufacturing facility established in 2023), Taiwan, Singapore, the USA (San Jose and Dallas), France, and Germany and Japan. Channel partners — including Teltec (China, Malaysia, Thailand, Vietnam, Indonesia/Singapore), ZMC China, U4Global UK, and JT Solutions Japan — extend sales and service coverage into Southeast Asia and additional geographies. Revenue is generated primarily through one-time capital equipment sales; the company is co-led by Co-CEOs Yu Wan-sik (유완식, 兪莞植) and Kim Ji-seok (김지석). Per the Korean homepage, sales revenue stood at approximately 257.6 billion KRW with stated headcount of 337 employees; the CEO has publicly disclosed an 85% direct-export ratio, a 70% growth target for 2025, and an ambition of 2 trillion KRW in revenue by 2030.

Direct peers

• MPI Corporation: Taiwan-based manufacturer of probe stations for semiconductor and photonics test, with strong Asia-Pacific fab relationships. Comparable product/customer base to SEMICS, especially in Taiwan and mainland China.
• FormFactor: Leading US-based wafer prober and probe card manufacturer serving advanced-node logic and memory customers globally. Most direct competitive overlap with SEMICS in wafer-level probe stations for semiconductor test.
• Toray Engineering: Japanese supplier of wafer probers and coater/developer systems. Direct competitor in Asia for wafer-level probe stations, with established relationships at Japanese IDMs and foundries.
• Cohu: US-headquartered supplier of test handlers, contactors and interface solutions for semiconductor final test. Overlaps with SEMICS at the wafer test-to-final-test boundary and competes for the same fab/OSAT budgets.
• Accretech (Tokyo Seimitsu): Japanese maker of wafer probers and dicing/grinding equipment, with decades of installed base at Asian fabs. Direct overlap with SEMICS' OPERA, OPUS5 and OPERETTA prober lines, particularly in memory and analog test.

Broad incumbents

• Onto Innovation: US-based inspection, metrology and process control equipment supplier serving advanced packaging and logic/memory fabs. Competes with SEMICS indirectly for fab capex allocated to electrical test vs. optical/inspection.
• Advantest: Global leader in semiconductor automated test equipment (ATE) and increasingly in test cell/probe integration. Adjacent rather than head-to-head with SEMICS but competes for the same memory/logic test capex dollars.
• Tokyo Electron: Largest Japanese semiconductor equipment OEM with broad process and test tool portfolio including wafer probers. Competes with SEMICS in probe stations but offers many adjacent process tools to the same customers.

Regional players

• Korea Instrument (KITech) / Korean prober specialists: Korean semiconductor equipment specialists and research institutes developing prober and test technologies domestically. Comparable regional positioning to SEMICS in the Korean fab ecosystem but generally smaller scale.

Emerging players

• Hprobe: Emerging player focused on magnetic and emerging-memory test solutions with specialized probe heads. Niche overlap with SEMICS in next-generation device test and a potential partner or competitor depending on customer roadmap.
