Advanced Packaging Capacity Crunch: AI Chip Demand Triggers Southeast Asia Expansion Wave
On July 28, 2026, the global semiconductor industry reached another critical turning point. According to the latest data from market research institutions, the capacity utilization rate for advanced packaging has exceeded 95%, especially for 2.5D/3D packaging and Chiplet integration technologies required for AI chips, with order lead times extending to over six months. Industry insiders point out that the explosion in demand for AI servers and edge computing devices is driving the packaging industry into a new cycle of expansion.
Supply-Demand Imbalance: AI Chips as the Driver
High-end AI chips such as NVIDIA's B300, AMD's MI400, and various custom ASICs heavily rely on advanced packaging technologies to integrate memory and logic chips. As traditional Moore's Law slows down, Chiplet architecture has become key to sustaining performance improvements. However, the complexity of advanced packaging processes is far higher than that of traditional packaging, causing capacity expansion to lag behind demand. Industry sources reveal that TSMC's CoWoS (Chip-on-Wafer-on-Substrate) capacity reservations have been scheduled into the first quarter of 2027, with no sign of easing shortages.
Rise of Southeast Asia: Thailand and Malaysia Become Expansion Hubs
To alleviate capacity pressure, global OSAT giants are turning their attention to Southeast Asia. Thailand and Malaysia, with their mature electronics supply chains and policy incentives, have become the preferred locations for new factories. ASE announced in the second quarter of 2026 that it would build a second advanced packaging plant in Chachoengsao Province, Thailand, with production expected to start in the second half of 2027, mainly serving U.S. AI customers. In addition, Penang, Malaysia, has attracted investment from several Chinese OSAT companies focusing on Chiplet interposers and fan-out wafer-level packaging (FOWLP).
Surge in Demand for Equipment and Materials
The expansion wave directly boosts the equipment and materials market. According to the latest report from SEMI, global packaging equipment sales are expected to grow 18% year-on-year in 2026, with advanced packaging equipment accounting for over half. Japanese DISCO and Tokyo Electron's grinding and bonding equipment are in short supply; Dutch ASM International's atomic layer deposition (ALD) equipment is also being used in thin-film processes for packaging. On the materials side, ABF substrates, underfill, and thermal interface materials continue to see price increases, prompting manufacturers such as Nan Ya Plastics and Ajinomoto to expand production.
Industry Challenges and Future Outlook
Despite the bright prospects, advanced packaging still faces two major challenges: technology and cost. Heat dissipation issues in 3D packaging, yield control in heterogeneous integration, and high equipment investment make it difficult for small and medium-sized OSAT companies to keep up. Experts predict a wave of consolidation in the next two years, with companies possessing advanced packaging capabilities dominating the market. In the short term, AI chip demand will continue to drive capacity expansion in Southeast Asia, with new plants gradually ramping up production after 2027, which is expected to alleviate supply bottlenecks.
Key Data at a Glance
- Advanced packaging capacity utilization: >95%
- Lead time: more than 6 months
- 2026 packaging equipment sales growth rate: +18%
- Main expansion locations: Chachoengsao Province, Thailand; Penang, Malaysia
In summary, advanced packaging has become a new engine for the growth of the semiconductor industry, and Southeast Asia is at the forefront of this wave. Investors and supply chain players should closely monitor capacity dynamics and technological iterations to seize opportunities amid changes.
