The Korea semiconductor equipment market took delivery of $25.8 billion of tools in 2025, up 26 percent year on year and third worldwide behind China and Taiwan, per SEMI’s Worldwide Semiconductor Equipment Market Statistics report of April 2026. Samsung Electronics and SK hynix account for most of it: their 2025 chip capital budgets alone exceed SEMI’s entire Korea figure. SEMI publishes no buyer-level split, so that concentration is an inference from disclosed capital expenditure, not a measured share.
The guide to Korea semiconductor market access covers the entry sequence and the regulatory route. This page covers the demand side: how large the market is, who signs, what domestic makers hold, and which slices a new entrant can address.
How Big Is the Korea Semiconductor Equipment Market?
Billings to Korea reached $25.8 billion in 2025 against $20.5 billion in 2024, per SEMI’s April 2026 WWSEMS release. The global total was $135.1 billion, up 15 percent: China $49.3 billion, Taiwan $31.5 billion, then Korea, with every other region below $11 billion (North America $10.9 billion, Japan $9.5 billion, rest of world $5.2 billion, Europe $2.9 billion). SEMI counts billings by ship-to destination, so a tool a Korean chipmaker installs overseas lands in another region. Korea’s figure is tools arriving on Korean soil, the number that sizes local service coverage and spares.
Where those tools may then move is now a procurement variable. The US Bureau of Industry and Security revoked Validated End User authorization for Samsung’s and SK hynix’s China fabs effective December 31, 2025, in a rule announced on August 29, 2025 and published in the Federal Register on September 2, 2025. Reuters reported on December 30, 2025 that both received one-year licences for 2026 shipments, and on August 4, 2026 that both have been evaluating etch tools from China’s AMEC as a hedge against tighter US controls, a report both disputed. Korean buyers testing non-US alternatives widen the field a new entrant is measured against, and a qualification package now carries a China-exposure disclosure that survives annual renewal.
SEMI’s 300mm Fab Outlook of April 1, 2026 projects 300mm fab equipment spending of $133 billion in 2026 and $151 billion in 2027. That series is 300mm only, a narrower base than the $135.1 billion all-equipment total, and $133 billion is an 18 percent rise on a 2025 300mm base near $113 billion.
Who Actually Buys Semiconductor Equipment in Korea?
Samsung Electronics and SK hynix. Won figures here convert at KRW 1,400 to the US dollar.
Samsung reported 2025 capital expenditure of roughly KRW 52.7 trillion, KRW 47.5 trillion of it in Device Solutions, per its 2025 fourth quarter disclosure. On March 19, 2026 it said it would spend more than KRW 110 trillion on chip capital expenditure and R&D in 2026, per Bloomberg; first half 2026 capital expenditure hit a record KRW 28 trillion, KRW 16.8 trillion of that in the second quarter, per Seoul Economic Daily on July 30 and August 14, 2026. SK hynix invested KRW 30.2 trillion in facilities in 2025 and has guided 2026 to the high KRW 40 trillion range, per its 2025 results and July 2026 earnings call.
Samsung’s Device Solutions line plus SK hynix’s 2025 facilities investment is KRW 77.7 trillion, about $55 billion, against a market SEMI sizes at $25.8 billion; that base excludes Samsung Display and non-chip spending. Those budgets also fund construction, land, and R&D, and some tools ship to Samsung Taylor and Xi’an or SK hynix Wuxi and Dalian, billed to other regions. Capital expenditure is a proxy for demand rather than a measure of it.
Below them sits a smaller tier, starting with specialty foundries DB HiTek and SK keyfoundry. SK siltron belongs in its own category: Korea’s only domestic silicon wafer maker buys crystal pullers, wire saws, lappers, polishers, and epitaxial reactors rather than a foundry tool set, and SK Inc. signed a share purchase agreement on July 31, 2026 to sell a 70.6 percent stake to Doosan for about KRW 2.3 trillion, roughly US$1.6 billion, closing expected by end of January 2027 subject to regulatory approval, per Dechert and the Korea Herald. Hana Micron, SFA Semicon, Nepes, and LB Semicon form the back-end base, the likeliest place to earn a first Korean reference, and the National NanoFab Center in Daejeon, whose 12-inch test bed opened to outside users in March 2021 per the Korea Herald, validates supplier tools at wafer level without a customer fab. That tier is a qualification route rather than a revenue plan.
구매 (purchasing) issues the order once the technical decision is settled. The tool-of-record call belongs to 공정기술 (process engineering) for the step, working with 설비기술 (equipment engineering), which owns uptime and spares. At Samsung the 설비기술연구소 (equipment technology research institute) in Device Solutions evaluates the major tool types, per its DS recruitment site; at SK hynix the 양산기술 (mass production technology) organization runs on paired process and equipment engineers, per SK hynix Newsroom. 인프라기술 (infrastructure engineering) owns the sub-fab. Each has an effective veto, and the 설비기술 read on your service organization carries the weight set out in the guide to semiconductor after-sales service in Korea.
A second buying route runs through construction into the sub-fab. Samsung C&T holds the structural contract for Pyeongtaek P5, in main construction since April 2026 for a 2028 production start, per Seoul Economic Daily and Digitimes, and SK ecoplant builds the Yongin cluster. Facility and sub-fab purchase orders frequently come from the contractor, and below it a mechanical, electrical, and cleanroom specialist tier holds those packages: Shinsung E&G booked a KRW 15.6 billion cleanroom contract for P5 phase 1 in mid-2026, per Money Today. Subcontractors and their material selections still carry the chipmaker’s approval, so the route in is the facility specification at design stage and the approved vendor list before packages are let. By the time the contractor places orders, the decision is made.
Both buyers publish a front door. Samsung runs 협력회사 등록 (partner company registration) through its International Procurement Center and Global Supplier Relationship Management system, and its supply chain disclosure records 35 new supplier proposals reviewed by Device Solutions in 2025. SK hynix uses gpis.skhynix.com, which requires a credit rating of B or higher, a year of operating history, and real-name authentication under a Korean-national employee where the representative is a foreign national. In my experience here, evaluation begins when an engineering sponsor inside the owning process group asks for it. Registration is the paperwork that follows.
How Much of the Market Do Korean Domestic Equipment Makers Hold?
Nine Korean semiconductor and display equipment makers posted 2025 revenue above KRW 500 billion, roughly KRW 8.8 trillion combined, per The Elec on April 2, 2026. SEMES led at KRW 2.4575 trillion and SFA Engineering at KRW 1.6309 trillion, with seven others, Wonik IPS and KC among them, between KRW 515.7 billion and KRW 909.7 billion each.
Three qualifications matter before converting that into share. Several of those names are weighted toward display equipment, some of the revenue is export, and the largest is captive: Samsung holds 91.54 percent of SEMES, and 97.4 percent of SEMES revenue in 2025, KRW 2.4077 trillion of KRW 2.4713 trillion on a consolidated basis, came from Samsung and its overseas subsidiaries. The ranking figure above is the parent-company revenue The Elec used to rank the nine makers, which is why the two totals differ.
At KRW 1,400 to the dollar, KRW 8.8 trillion is about $6.3 billion, roughly a quarter of Korea’s 2025 billings, and a loose upper bound rather than a share: it divides company revenue by ship-to billings, counts SEMES output going to Samsung’s overseas fabs, and counts display equipment. The contestable portion is smaller still.
Korea’s 2022 Semiconductor Superpower Strategy targets raising self-sufficiency in materials, parts, and equipment from about 30 percent to 50 percent by 2030, with programs funding domestic alternatives in etch, deposition, and cleaning. With no domestic extreme ultraviolet lithography capability, that pressure concentrates where a domestic challenger is plausible.
Which Foreign Suppliers Hold the Korean Installed Base?
The incumbents are the five global names that hold every other advanced market, disclosed on different reporting bases, so read the figures as indicators, not as one comparable set. ASML put South Korea at 25 percent of net system sales in calendar 2025, per its 2025 annual report. Lam Research put Korea at 22 percent of revenue in fiscal 2025, its second largest geography, and Applied Materials at about 20 percent of fiscal 2025 net revenue, per their Form 10-Ks. KLA reported Korea at $1.45 billion, 12 percent of fiscal 2025 revenue on a ship-to basis, per its fiscal 2025 Form 10-K. Tokyo Electron reported South Korea at JPY 152.4 billion of JPY 732.3 billion in net sales, 20.8 percent, for the quarter ended June 2026, per its quarterly consolidated results. Those are company revenue bases including service, spares, and tools installed outside Korea, so they do not add against SEMI’s $25.8 billion ship-to figure, and neither does the domestic share above.
Tool-of-record positions at mature steps are effectively closed to a new entrant. A fab that has run a deposition platform across three nodes has integration history, a spares pool, a trained maintenance team, and yield data attached to it, and displacing it takes a documented process advantage at a new node and years of evidence; price alone moves nothing. Parts and consumables run on different rules, where second-source qualification is won largely on price, lead time, and local stock.
What Share Is Addressable to a New Entrant?
Work down from $25.8 billion by subtraction: remove lithography, where ASML holds a leading-edge monopoly; the captive SEMES scope inside Samsung; locked tool-of-record positions in running lines; and the categories where localization favors a domestic challenger.
Greenfield capacity is the first opening, because a new line has no incumbent for a step that did not exist before, and the timing is visible. SK hynix finished civil and structural work on its first Yongin fab and entered the cleanroom infrastructure phase by July 2026, targeting first cleanroom operation in February 2027, per Cleanroom Technology. Its board approved KRW 54 trillion in August 2026 for Yongin Y2 and Cheongju M17, cleanrooms due June 2029 and December 2028, per SK hynix Newsroom, and it has pulled full cluster completion forward from 2045 to 2033, per the Korea Herald. The two separate Yongin projects, SK hynix memory fabs in Wonsam and Samsung’s system semiconductor complex at Idong-Namsa, run on different schedules and different procurement paths, set out in the guide to the Yongin semiconductor cluster and its two projects. Those sites and Samsung’s Pyeongtaek build-out sit in the overview of Korea’s semiconductor industry and the K-Semiconductor Belt. Sub-fab scope for a fab already in fit-out is being specified now.
Advanced packaging is the second, with newer steps and a less settled tool-of-record hierarchy. Sub-fab and facility systems are the third: gas and chemical delivery, abatement, ultrapure water, and cleaning chemistries, bought through the contractor channel above. Metrology and inspection gaps at advanced nodes are the fourth. Parts, consumables, and service are the fifth: a running tool consumes them for its whole service life, and that revenue renews without a fresh capital approval.
None of it is addressable if the tool cannot be installed. Equipment going onto a Korean fab floor clears safety compliance first: KC marking where the product falls in scope, KOSHA safety certification under the Occupational Safety and Health Act for machinery in scope, and the SEMI S2 and S8 evaluations Korean fabs expect in a qualification package. Budget that into the schedule rather than meeting it at import.
Qualification in a Korean fab runs 12 to 18 months or longer, as the fab qualification process in Korea sets out. Tools shipping against the 2026 and 2027 budgets went largely to suppliers who qualified in 2024 and 2025, so a program starting now sells into the cycle after this one. Most foreign suppliers run through a local partner, and the criteria for selecting a semiconductor distributor in Korea decide whether it opens engineering doors or forwards email.

Frequently Asked Questions
How big is the Korea semiconductor equipment market? Billings to Korea reached $25.8 billion in 2025, up 26 percent from $20.5 billion in 2024, per SEMI’s WWSEMS report of April 2026, third behind China at $49.3 billion and Taiwan at $31.5 billion in a global $135.1 billion.
Who buys semiconductor equipment in Korea? Samsung Electronics and SK hynix. Their 2025 chip capital budgets, KRW 47.5 trillion for Samsung Device Solutions and KRW 30.2 trillion for SK hynix facilities, come to about $55 billion at KRW 1,400 to the dollar, more than double SEMI’s $25.8 billion of Korean billings, and no one else operates a leading-edge fab here. SEMI publishes no buyer-level split. Below them sit DB HiTek, SK keyfoundry, wafer maker SK siltron, the OSATs, and research fabs.
How much semiconductor equipment does Korea make domestically? Korea’s nine largest semiconductor and display equipment makers posted combined 2025 revenue of roughly KRW 8.8 trillion per The Elec, April 2026, part of it display and export sales, and the largest, SEMES, is 91.54 percent Samsung-owned and booked 97.4 percent of that revenue from Samsung and its overseas subsidiaries. Korea has no domestic EUV capability.
Can a foreign supplier sell equipment to Samsung or SK hynix without a Korean partner? Large global suppliers with Korean subsidiaries do. Smaller entrants generally cannot. Vendor registration, 세금계산서 (tax invoice) issuance, and payment run on a 사업자등록번호 (business registration number), since the Value-Added Tax Act requires a registered business to issue a Korean tax invoice, and SK hynix’s portal adds credit rating and operating history tests. Service is the other barrier, and response is measured in hours around the clock. The qualifying step is an engineering sponsor in the process group that owns the decision.
