China’s Advanced Packaging Industry Growth
Definition: China’s advanced packaging industry—the segment of semiconductor manufacturing that integrates multiple chips (e.g., chiplets, 3D stacking, fan-out wafer-level packaging) into a single, high-performance module—is projected to reach US$18.7 billion in domestic market value by 2026, up from US$11.3 billion in 2023, representing a compound annual growth rate (CAGR) of roughly 18%. This rapid expansion is driven by rising demand for AI accelerators, 5G/6G infrastructure, and automotive electronics—sectors that rely on packaging to overcome the limits of traditional Moore’s Law scaling. For foreign executives making China decisions, understanding this growth trajectory is essential for supply chain strategy, partnership evaluation, and regulatory risk assessment.
Key Contextual Numbers and Their Meaning
To gauge the scale and pace of change in China’s advanced packaging ecosystem, consider these four pivotal figures:
- US$18.7 billion – the projected domestic advanced packaging market size by 2026, which would give China ~22% of the global advanced packaging market (estimated US$85 billion). This share is up from ~16% in 2020, underscoring deliberate national investment.
- 45+ new fabs – the number of advanced packaging and assembly facilities either under construction or announced in China from 2022 to 2025 (includes both domestic firms and foreign joint ventures). These fabs are concentrated in Shanghai, Beijing, and the Yangtze River Delta, and represent total investment of over US$80 billion.
- 3.8× patent filings – the increase in Chinese patent applications for advanced packaging technologies (including TSV, hybrid bonding, and fan-out) from 2019 to 2024, according to the China National Intellectual Property Administration. This signals a shift toward indigenous R&D rather than mere imitation.
- 70% packaging localization – the target set by China’s “National Integrated Circuit Industry Development Guidelines” (国家集成电路产业发展推进纲要 guójiā jíchéng diànlù chǎnyè fāzhǎn tuījìn gāngyào) for domestic packaging supply by 2025. While traditional packaging is already heavily localized, advanced packaging currently sits at ~35% localization, implying a massive coverage gap that local firms are racing to close.
These numbers highlight a deliberate, state-backed push to capture value in higher-margin, technology-intensive segments of the semiconductor value chain—especially critical as US export controls tighten on advanced chip manufacturing.
Drivers of Growth: Domestic Demand and Policy Support
1. Domestic chip demand explosion. China consumed ~60% of the world’s semiconductors in 2023, yet its domestic production (advanced packaging included) covered less than 20% of that demand. The rise of AI inference (e.g., for Baidu’s ERNIE bot), autonomous driving (BYD, NIO), and 5G base stations (Huawei) requires high-density interconnect packaging that reduces latency and power consumption. These sectors are the primary demand drivers for advanced packaging in China, pushing foundries and OSATs (outsourced semiconductor assembly and test providers) to accelerate capabilities.
2. Government subsidies and incentives. Under the “National IC Industry Development Guidelines” (2014, updated 2021), advanced packaging is a “Priority Category” eligible for corporate tax breaks, R&D grants, and low-interest loans. Local governments in Shanghai, Wuxi, and Shenzhen have each launched dedicated funds worth US$2–5 billion for advanced packaging projects. For example, the Shanghai Advanced Packaging Industrial Park, opened in 2022, hosts 10+ packaging lines with combined monthly capacity of 100,000 wafers.
3. Forced localization due to trade tensions. The US CHIPS Act and export controls on EDA tools, semiconductor equipment, and advanced logic chips have forced Chinese companies to find alternative solutions. Advanced packaging—which uses more accessible tools like wafer bumping, underfill, and test handlers—is viewed as a “workaround” to improve performance without needing cutting-edge EUV lithography. This has led to a surge in orders for domestic packaging houses like JCET (江苏长电科技 Jiāngsū Chángdiàn Kējì) and Tongfu Microelectronics (通富微电子 Tōngfù Wēi Diànzǐ).
Key Technologies and Chinese Players
Technologies Gaining Traction
| Technology | China Adoption Status | Key Applications |
|---|---|---|
| Fan-Out Wafer-Level Packaging (FOWLP) | Mass production launched by JCET and Tongfu in 2023; yields above 95% | RF front-end modules, power management ICs, AI edge devices |
| 3D Hybrid Bonding | Pilot lines at SMIC (中芯国际 Zhōngxīn Guójì) and Huali; partner with Huawei HiSilicon | CMOS image sensors, logic-to-memory stacking, HBM memory cubes |
| System-in-Package (SiP) | Widely used for wearables (e.g., Xiaomi, Huawei), automotive ECUs | IoT modules, sensor hubs, signal processing |
| Embedded Die Fan-Out (eFO) | Supplied by Siliconware Precision Industries (SPIL) through its Chinese JVs | Radio-frequency and mmWave antennas |
Major Domestic Players
JCET (江苏长电科技) is China’s largest OSAT and the global No. 3 by revenue (US$4.5 billion in 2023). It operates advanced packaging lines in Jiangyin, Shanghai, and Korea, and has licensed technologies from STATS ChipPAC. Its 3D packaging capacity rose 40% YoY in 2024, driven by orders from Chinese AI chip startups.
Tongfu Microelectronics (通富微电子) focuses on memory packaging (with DRAM maker CXMT) and high-pin-count BGA packages for CPUs and GPUs. In 2024, it broke ground on a new facility in Suzhou dedicated to hybrid bonding and fan-out processes, with an initial capacity of 50,000 wafers/month.
Amkor Technology China (a subsidiary of US-headquartered Amkor) operates large packaging plants in Shanghai and Suzhou. While subject to US export rules, it remains a key supplier for foreign chipmakers assembling in China. However, its technology transfer to local partners is restricted, creating a gap that domestic firms are eager to fill.
Challenges and Global Competition
Despite the rapid growth, China’s advanced packaging sector faces several headwinds:
- Equipment dependency: Key tools like bonders, die sorters, and inspection systems are still heavily sourced from Japan (Disco, Shinkawa) and the US (KLA, Applied Materials). Export controls on certain packaging equipment (e.g., for hybrid bonding alignment) have forced Chinese firms to stockpile and develop domestic alternatives—but progress is slow.
- Yield and reliability gaps: While JCET and Tongfu achieve yields of 92–95% for FOWLP, leading global peers (TSMC’s InFO, Samsung’s ePoP) maintain 97–99% yields. The gap is narrower than in logic manufacturing, but significant for high-reliability applications like automotive.
- Intellectual property friction: US-based packaging patents (e.g., for hybrid copper bonding) are held by companies like Intel and Micron. Chinese firms are filing their own IP, but litigation risks remain, especially if they export products using packaging methods that infringe on foreign patents.
- Cost pressure: Advanced packaging adds 15–30% to total chip cost compared to traditional packaging. In China’s price-sensitive consumer electronics market, many OEMs still opt for cheaper, less sophisticated packaging. The cost gap is expected to narrow as volumes scale and Chinese equipment costs fall.
Global competition is fierce. Taiwan’s ASE Group holds ~30% of the worldwide advanced packaging market, and TSMC’s CoWoS and InFO technologies dominate high-end AI accelerators. China’s OSATs are still below the technology frontier, but they are closing the gap at a faster rate than in logic fabrication—meaning foreign executives should watch for cost-competitive Chinese alternatives in mid-range applications (e.g., automotive infotainment, edge AI, 5G small cells) within the next 2–3 years.
NEXT STEPS
For foreign executives evaluating their semiconductor strategy in China, three decision-path recommendations emerge:
- Assess partnership risks and opportunities with Chinese OSATs. If you are a fabless chip designer selling into China, consider engaging JCET or Tongfu for package assembly and test (OSAT services) to reduce supply chain vulnerability to trade controls. However, conduct thorough due diligence on IP protection clauses, equipment bottlenecks, and potential geopolitical implications of sharing package designs with Chinese partners.
- Monitor technology migration timelines for hybrid bonding and 3D stacking. Chinese foundries (SMIC, Huahong) are actively integrating packaging with front-end processes. If your next-generation chip requires hybrid bonding or chiplets with ultra-fine pitch, China may not be a viable assembly site until 2027–2028. Plan dual sourcing (e.g., Taiwan for high-end, China for mid-range) accordingly.
- Prepare for “localization premiums” on packaging. China’s 2025 localization target for advanced packaging will likely be missed (expected ~45% instead of 70%). But tax incentives and government procurement preferences will continue to favor domestic packaging providers. Foreign companies building fabs or OSATs in China should budget for a 15–20% cost premium compared to global benchmarks due to import duties on equipment, smaller scale, and yield learning curves. Meanwhile, consider licensing your own packaging IP to Chinese partners via joint ventures—this can provide revenue while navigating local content requirements.
