SMEE

Shanghai Micro Electronics Equipment (Group) Co., Ltd. (上海微电子装备; SMEE) was established in 2002 as a state-owned enterprise under Shanghai's municipal government and China's national semiconductor equipment strategy, with the explicit mandate of building a domestic lithography industry. Lithography — the process of projecting circuit patterns onto silicon wafers using precisely focused light — is the single most technologically demanding step in chip manufacturing, and for two decades one company, ASML of the Netherlands, has held an effective global monopoly on the extreme ultraviolet (EUV) tools required for leading-edge logic. SMEE is China's only serious domestic attempt to build an alternative, and it remains the country's sole hope of eventually closing that gap, however distant that prospect looks today. The technological distance between SMEE and ASML is stark. SMEE's mainstay "600 series" deep ultraviolet (DUV) scanners are in mass production at the 90nm node — a process generation ASML itself commercialized in the early 2000s — while a 28nm-class immersion DUV model has been in development for years. EUV lithography, which ASML has supplied since 2018 and which is required for any logic process at 7nm and below without extreme multi-patterning workarounds, remains entirely out of reach for SMEE: the tool requires mastering plasma-generated 13.5nm-wavelength light sources, multilayer mirror optics accurate to atomic-scale tolerances, and vacuum photomask handling systems that took ASML, Zeiss, and Cymer more than two decades and tens of billions of dollars of combined R&D to perfect. This gap is precisely why lithography is the single most heavily export-controlled equipment category in the entire semiconductor supply chain: the Netherlands, Japan, and the United States coordinate export licensing specifically to keep EUV and increasingly advanced DUV tools out of China, on the theory that if China cannot buy or build the tool, it cannot manufacture the chip, regardless of how much progress it makes elsewhere in the stack. Washington formally placed SMEE on the US Entity List in December 2022, citing the acquisition of US-origin items in support of China's military modernization, and applying a license-review policy of presumption of denial — the strictest tier of Entity List restriction. That listing appears to have catalyzed a significant corporate restructuring rather than simply freezing SMEE in place. In February 2025, SMEE spun off its front-end lithography R&D into a new subsidiary, Shanghai Yuliangsheng Technology, which industry reporting has linked closely to Huawei's "SiCarrier" domestic semiconductor-toolmaking initiative. Yuliangsheng — reportedly developing its DUV scanner under the internal codename "Mount Everest" — is now testing what is described as China's first domestically engineered 28nm-class immersion DUV lithography system, installed for evaluation directly at SMIC. Analysts tracking the program expect it could reach mass production at SMIC's 28nm node as early as 2027, but caution that redesigning the scanner for the multi-patterning schemes needed at 16nm, and eventually 7nm-class nodes, will likely take until 2030 or later — a reminder that even a successful 28nm DUV tool is several node generations and years of engineering away from threatening ASML's advanced-node monopoly. Separately, in a restructuring first reported in 2025 and continuing into January 2026, SMEE spun off its back-end, post-lithography packaging-equipment assets into a newly separate commercialization entity called AMIES Technology — notably, a company that was not itself placed under the same Entity List restrictions as its parent. AMIES rapidly acquired thousands of SMEE patents and at least two SMEE subsidiaries in the process, and by late 2025 TrendForce reporting credited AMIES's advanced-packaging lithography tools with capturing roughly 90% of the relevant segment of China's domestic packaging-lithography market and as much as 35% of the equivalent global segment — a niche distinct from full front-end scanners, covering steppers used in chip packaging and redistribution-layer patterning rather than leading-edge logic printing. AMIES shipped its 500th stepper system in August 2025, evidence that the spinoff strategy has functioned as intended: isolating the commercially viable, less export-sensitive packaging-lithography business from the heavily sanctioned front-end scanner business. The resulting corporate structure is genuinely fragmented and easy to conflate: SMEE remains the state-owned parent and the entity actually on the Entity List, continuing front-end lithography strategy and oversight; Shanghai Yuliangsheng is the Huawei/SiCarrier-linked subsidiary doing the frontline DUV scanner engineering now under test at SMIC; and AMIES is the separately commercialized back-end packaging-equipment spinoff, structured in a way that appears designed to operate outside SMEE's direct sanctions exposure. Taken together, this three-way structure illustrates both the seriousness and the limits of China's lithography self-sufficiency push: real, if incremental, progress at the packaging and mature-node DUV layer, deliberate corporate engineering to route around export controls, and still no credible path to EUV — the chokepoint that will keep China's most advanced logic chips dependent on foreign fabrication for the foreseeable future.
