Semiconductor Manufacturing International Corporation (SMIC)
China's leading integrated circuit wafer foundry, offering process technologies ranging from 0.35μm to 14nm.
Benefiting from domestic substitution and massive domestic demand, it is the leading wafer foundry in China, but access to advanced process equipment is severely restricted.
Company Overview
Semiconductor Manufacturing International Corporation (SMIC) was founded in 2000, listed on the Hong Kong Stock Exchange in 2004, and debuted on the Shanghai Stock Exchange's STAR Market in 2020. Its headquarters is in Shanghai. The company is the largest and most technologically advanced integrated circuit wafer foundry in mainland China, primarily providing wafer foundry services from 0.35μm to 14nm FinFET and more advanced nodes. In the full AI industry chain, SMIC is positioned at the "Semiconductor Manufacturing & Materials" layer and serves as the core pillar of domestic chip manufacturing.
SMIC's mature process technologies cover 0.35μm to 28nm, spanning platforms such as logic, mixed-signal, RF, BCD, CIS, and eNVM. These services primarily target domestic applications in consumer electronics, IoT, automotive electronics, and industrial control. Benefiting from the wave of domestic substitution, mature process capacity remains fully loaded and constitutes the company's revenue base.
Advanced processes include 14nm FinFET and the self-developed N+1 (equivalent to 7nm) and N+2 (equivalent to 5nm) nodes. Due to U.S. export controls, access to advanced process equipment is restricted, and current capacity mainly serves specific domestic customers (e.g., HiSilicon). The N+1 process has entered mass production, but yield and cost still require optimization. This business contributes relatively low revenue but carries significant strategic importance.
| Product Line | Revenue Share | Core Customers | Estimated Gross Margin |
|---|---|---|---|
| Mature processes | ~75% | Domestic IC design companies, IDMs | ~20% |
| Advanced processes | ~25% | HiSilicon, domestic CPU/GPU vendors | ~10-15% |
Technology Moat
Moat 1: Breakthrough in Proprietary FinFET Technology
SMIC is one of the few foundries worldwide capable of mass-producing FinFET processes. Despite being unable to obtain EUV lithography equipment, the company has achieved the N+1 process equivalent to 7nm through multi-patterning technology and continues to advance N+2 development. This technical capability provides the only domestic foundry option for high-end domestic chips.
Moat 2: Domestic Policy and Market Barriers
SMIC receives continuous investment from the National Integrated Circuit Industry Investment Fund (the "Big Fund"), as well as local government support in terms of land, electricity, and tax incentives. Facing geopolitical risks, domestic chip design companies tend to prioritize SMIC, creating deep customer stickiness and locked-in relationships.
| Dimension | Data |
|---|---|
| Global market share | 5.2% (2023, TrendForce data) |
| Industry ranking | Third globally (excluding IDMs, pure-play foundry only) |
| Main competitors | TSMC (59%), Samsung Electronics (7.1%), UMC (4%) |
| Downstream customers | HiSilicon, UNISOC, Will Semiconductor, domestic AI chip startups |
Note: Even when including IDM foundry services, SMIC remains among the top players. The advanced process market is primarily dominated by TSMC and Samsung, while SMIC is more competitive in the mature process market.
Financials and Growth
| Metric | Data |
|---|---|
| Revenue (2023) | Approximately $6.32 billion (RMB 45.2 billion) |
| Gross margin | 19.3% |
| Net margin | Approximately 9.1% |
| Core growth logic | 1) Domestic substitution drives sustained demand growth for mature processes; 2) AI, IoT, electric vehicles and other downstream applications boost wafer foundry volume and pricing; 3) If equipment restrictions are overcome in advanced processes, new growth headroom will open up. |
In 2023, revenue declined approximately 13% year-over-year, mainly due to the semiconductor downturn and equipment export controls. However, in 2024, benefiting from a recovery in consumer electronics and inventory replenishment by domestic customers, revenue is expected to return to growth.
Key Risks:
- Escalating geopolitical tension: The U.S. continues to tighten export controls on semiconductor equipment to China, severely constraining SMIC's advanced process capacity expansion. The mass production timeline for nodes such as N+2 is highly uncertain.
- Industry cyclical volatility: The semiconductor industry is strongly cyclical, and overcapacity risks in mature processes may compress gross margins.
- Technology catch-up pressure: TSMC and Samsung lead by more than two generations in advanced processes. If SMIC cannot obtain EUV equipment, its technology roadmap below 7nm will hit a ceiling.
Core Investment Logic / Summary of Industrial Value:
SMIC is a scarce core asset in China's semiconductor manufacturing segment. In the short term, equipment controls limit its advanced process breakthroughs. However, under the national strategy of IT application innovation (Xinchuang) and domestic substitution, its mature process business will maintain steady growth. In the long run, if geopolitical tensions ease or domestic equipment achieves breakthroughs, the company has the potential to become the world's third-largest pure-play foundry and an irreplaceable "manufacturing cornerstone" in the AI industry chain.
