What EQ GLOBAL Inc. does

EQ GLOBAL Inc. (주이큐글로벌) is a South Korea-headquartered semiconductor equipment solutions provider founded in December 2001, specializing in the repair, refurbishment, and modification of radio frequency (RF) power and plasma control equipment used in semiconductor and display manufacturing. Its portfolio spans RF Generators (600W to 10kW), RF Matchers (380kHz to 27MHz), Remote Plasma Sources (RPS, 2L to 30L), Microwave systems, RF Filters, Plasma Abatement Systems (PAS), and board-level test-equipment repair for Advantest, Teradyne, and Yokogawa testers. The company also manufactures proprietary drop-in replacement RF products (EQG series) that substitute for discontinued OEM equipment from ENI, AE, and DAIHEN, supported by 18+ Korean patents and one Chinese patent plus ISO 9001, ISO 14001:2015, and AMAT ISAT certifications. EQ GLOBAL operates as a 76.01%-owned subsidiary of SurplusGlobal, embedded within the SurplusGlobal Semiconductor Equipment Cluster in Yongin.

The business model is a mix of professional repair services (approximately 80% of FY2024 revenue of ~230 billion KRW, ~$170M USD) and proprietary equipment sales (approximately 20%). Go-to-market combines direct enterprise field sales — engineers stationed inside Samsung Display (Asan), SK Hynix (Wuxi), Intel (Arizona), and Micron (Singapore) fabs — with channel leverage through SurplusGlobal's global used-equipment marketplace and the TensorVault online platform for the new GPU server restoration line. With ~95 employees and stated ~2,000 units/year repair capacity, the company claims the largest Korean semiconductor RF parts repair operation, serving SK Hynix, Samsung Electronics, Intel, Samsung Display, Micron, GlobalFoundries, UMC, and Amkor.

In 2025 the company appointed a new CEO (Choi Tae-ho, ex-SK Key Foundry VP) to lead global expansion, established a U.S. subsidiary in Phoenix, Arizona, and prepared a GPU server restoration business for AI data center customers via the TensorVault/SugarQube Networks platform. Management has publicly targeted 250B KRW in 2025, 600B KRW by 2027, and 1,500B KRW by 2032, alongside a stated objective of a KOSDAQ IPO.

Broad incumbents

• Lam Research: Lam Research is a major OEM whose plasma etch and CVD equipment populates EQ GLOBAL customer fabs — both a customer (whose equipment EQ GLOBAL services) and a competitive threat via Lam's own Customer Support Business Group that competes for repair service revenue.
• Advantest: Advantest is a major Japanese Automatic Test Equipment (ATE) manufacturer whose testers (T5377, T5588, T5833 series) EQ GLOBAL repairs and refurbishes as part of its Test Equipment Service line — a customer/partner dynamic where Advantest's own service organization overlaps with EQ GLOBAL's PCB board repair capabilities.
• Hitachi High-Tech: Hitachi High-Tech provides semiconductor manufacturing equipment and related services globally — a broader incumbent in the equipment ecosystem that competes for service, repair, and refurbishment revenue across fab customers that EQ GLOBAL also serves.
• Applied Materials: Applied Materials supplies semiconductor manufacturing equipment to the same major fabs EQ GLOBAL serves (Samsung, SK Hynix, Intel); EQ GLOBAL holds AMAT ISAT certification, positioning it as an authorized service partner while Applied Materials' service arm competes for the same legacy equipment maintenance wallet.

Direct peers

• Kyosan Electric Manufacturing: Kyosan Electric is a Japanese manufacturer of RF Power Supplies for semiconductor and display manufacturing — explicitly listed as one of the OEMs whose equipment EQ GLOBAL repairs and which competes with EQ GLOBAL's proprietary RF Generator line in the same Asian fabs.
• MKS Instruments: MKS Instruments manufactures RF Generators, RF Matchers, and Remote Plasma Sources (RPS) for semiconductor plasma processes — directly overlapping EQ GLOBAL's core product portfolio (MKS is named as an OEM whose RPS products EQ GLOBAL repairs via Revolution, Paragon, and 2L-30L series refurbishment).
• Advanced Energy Industries: Advanced Energy (AE) is the original manufacturer of the RFG-5500 and other RF Power Supplies that EQ GLOBAL's EQG-5000NP drop-in replacement targets — a direct head-to-head competitor in the RF Generator space serving the same semiconductor fab customers.
• AD-TEC (Advanced Design Technology): AD-TEC designs and manufactures RF Generators and plasma power supplies for semiconductor manufacturing — explicitly named in EQ GLOBAL's RF repair service portfolio and a direct competitor in the legacy RF Equipment replacement product category.
• Comet Group (Comet Yxlon / Plasma Control Technologies): Comet Group's Plasma Control Technologies division designs and manufactures RF Generators and impedance-matching networks for semiconductor and display manufacturing — a direct competitor to EQ GLOBAL's RF Generator and Matcher lines serving the same customers (e.g., Samsung Display, SK Hynix).

Others

• SurplusGLOBAL: SurplusGLOBAL is EQ GLOBAL's 76.01% parent company and operator of a global used semiconductor equipment marketplace and SemiMarket parts platform — not a direct competitor but an adjacent ecosystem partner that provides customer pipeline and co-located cluster facilities in Yongin.
