Origin
SMIC was founded in 2000 in Shanghai by Richard Chang, a Taiwan-born executive who had worked at Texas Instruments, with capital from international investors and support from the Chinese state. The founding model was straightforward: recruit experienced foundry engineers from Taiwan, buy Western and Japanese equipment, and compete on cost.
It worked well enough to prompt litigation from TSMC over trade secrets, settled in Taiwan’s favour, and the settlement left SMIC with a technology gap it has spent two decades trying to close.
Command
Listed in Hong Kong and Shanghai with a conventional board, and substantial state ownership through the National Integrated Circuit Industry Investment Fund and state-linked shareholders. Leadership has changed frequently, including departures of senior technical figures at points of strategic disagreement, which is unusual for a foundry and has cost the company continuity.
Capability
SMIC is China’s largest foundry and among the largest globally by revenue, with the bulk of output at mature nodes. Mature-node capacity is the part most often underrated by outside observers: the automotive, industrial and consumer markets run on it, and China’s share of that capacity has grown fast enough to prompt trade investigations in the United States and Europe.
The advanced-node question is the one that attracts attention. SMIC produced a 7nm-class part for Huawei in 2023 using deep ultraviolet lithography with multi-patterning, having been denied extreme ultraviolet tools. Reporting since has pointed to work at tighter nodes by the same route.
The constraint is not whether this can be done. It is yield and cost. Multi-patterning multiplies process steps, and every additional step multiplies defect opportunity. A node that is achievable at low yield and high cost supports flagship devices in limited volume. It does not support mass-market competition, and it does not support high-volume AI accelerator production.
Funding and ownership
Public equity, state investment funds, retained earnings and local government support for specific fabs. Capital intensity is extreme and the company has continued heavy capacity investment through the restriction period.
Restrictions and exposure
SMIC was added to the US Entity List in December 2020, with a presumption of denial for equipment capable of advanced-node production. Subsequent US, Dutch and Japanese controls tightened the position further, cutting access to extreme ultraviolet lithography entirely and restricting advanced deep ultraviolet tools, along with servicing and spares.
Servicing is the underappreciated constraint. Semiconductor equipment requires continuous vendor support, and a tool that cannot be maintained degrades. The effect compounds over years rather than appearing immediately.
Watch items
- Yield evidence at 7nm and below, inferred from device availability and pricing.
- Domestic lithography progress at SMEE and successors.
- Mature-node capacity additions and resulting trade actions abroad.
- Equipment servicing workarounds and parts sourcing through third countries.
