TSMC Packaging Capacity Becomes Key Bottleneck, Price Hike Expected in 2027

Overview

This report deeply analyzes Taiwan Semiconductor's (TSMC) core position in the AI semiconductor wave, focusing on its advanced packaging (CoWoS/SoIC) capacity expansion plans and pricing power. The report argues that despite macro fluctuations, structural demand brought by AI is strong, especially in the cloud AI semiconductor market. With technological leadership and monopolistic control over EUV lithography machine supply, Taiwan Semiconductor is expected to implement a 5%-10% price hike by 2027. Simultaneously, the report covers investment opportunities across the entire industry chain from wafer manufacturing to advanced packaging, test equipment, and power semiconductors, emphasizing value revaluation due to increased complexity in testing caused by AI chips.

Core views

Core Viewpoint One: Taiwan Semiconductor Pricing Power and Capacity Expansion. The report points out that Taiwan Semiconductor remains ahead in the technology roadmap and logic density, and is the only main beneficiary of EUV supply. It is expected that its leading process prices will rise by 5%-10% by 2027 to reflect its irreplaceable value to customers. In terms of capacity, CoWoS advanced packaging capacity is expected to expand significantly from current levels to 200,000 wafers/month by 2027 to meet customer needs such as NVIDIA and AMD. Demand for the 2nm node is also being gradually released, with diversified customer structure. Core Viewpoint Two: Explosive Growth of the AI Semiconductor Market. The total Cloud AI Semiconductor Market (TAM) may reach $235 billion in 2025, and the global semiconductor industry scale is expected to reach $1.5 trillion by 2030, half of which comes from AI semiconductors. Capital expenditure of the top four cloud service providers (Amazon, Google, Microsoft, Meta) grew 95% year-on-year in Q1 2026, showing continued investment in AI infrastructure. NVIDIA's GB200/300 rack shipments are ramping up quickly, driving demand across the entire supply chain. Core Viewpoint Three: Value Revaluation of Testing and Packaging Links. With the increase in AI chip pins and extended testing time, the test equipment and consumables market is seeing structural growth. The overall Test Handler market is expected to grow from $436 million in 2023 to $6.6 billion by 2027. Companies like WinWay, MPI, and Hon Precision are considered key beneficiaries due to their technological advantages in probe cards, sockets, and handlers. WinWay plans to increase its monthly capacity from 3.5 million probes in 2025 to 9 million probes in 2026. Core Viewpoint Four: Other Niche Market Opportunities. Regarding power semiconductors, due to decreased capital expenditure in the past two years, supply side tightness has emerged. The report prefers SiC (Silicon Carbide) over GaN (Gallium Nitride), recommending SICC and InnoScience. Regarding memory, AI leads to NAND shortages, and NOR Flash may also face supply shortages in 2026.

Analysis framework

The institution adopted an analysis method combining top-down and bottom-up approaches. First, industry prosperity was confirmed by tracking cloud provider capital expenditure and AI semiconductor total market size (TAM) (top-down). Second, Taiwan Semiconductor's technology roadmap, capacity utilization, customer structure (e.g., distribution of 2nm/3nm/5nm customers), and supply-demand balance sheet for advanced packaging (CoWoS/SoIC) were broken down in depth (bottom-up). Additionally, the report applied industry chain transmission logic, extending from GPU core manufacturers (NVIDIA) to downstream and upstream links such as packaging and testing, memory, and power devices, assessing supply-demand gaps and value changes in each link.

Methodology notes

• Industry/Industrial Analysis FrameworkSupply-demand framework

  Judging the bottleneck degree of the packaging link by analyzing the matching degree between the speed of CoWoS capacity expansion and the growth of AI chip demand.

  The research report compares TSMC's CoWoS capacity plan (supply) with customer demand (demand) such as NVIDIA, identifying that packaging is the key bottleneck for current AI chip shipments, thereby deriving the earnings elasticity of relevant equipment and foundries.

• Industry/Industrial Analysis FrameworkVolume/Price Breakdown

  Decomposing Taiwan Semiconductor's revenue growth into two driving factors: wafer shipment volume (volume) and average selling price (price).

  The report predicts that Taiwan Semiconductor will raise prices by 5%-10% in 2027, meaning even if shipment growth remains stable, the unit price increase will directly drive revenue and profit growth, which is the core logic for evaluating the profitability of foundry enterprises.

• Valuation MethodPE/PEG valuation

  Comparing Price-to-Earnings Ratio (PE) and profit growth rates of different semiconductor sub-sectors (foundry, packaging/testing, memory, IDM).

  The report seeks sub-sectors with relatively reasonable valuations or potential for revaluation by horizontally comparing valuation multiples across sub-sectors combined with their growth expectations. For example, the test equipment sector obtains higher valuation tolerance due to high growth.

Impact & implications

The research report believes that the recovery of Taiwan Semiconductor's pricing power and capacity expansion will consolidate its long-term earnings foundation; investors should pay attention to its capital expenditure efficiency in the advanced packaging field. For the supply chain, test equipment and advanced packaging material manufacturers will usher in structural growth opportunities because the complexity and testing requirements of AI chips have increased significantly. Supply tightness in power semiconductors and memory chips may also lead to price recoveries, benefiting relevant IDM manufacturers. Overall, AI semiconductors have moved from concept verification to large-scale deployment, and supply chain leaders will continue to benefit.

Risks

• AI demand falls short of expectations, leading to slowing capital expenditure
• Geopolitical tensions affect supply chain stability
• Technology iteration failure or slow yield improvement
