TSMC is reportedly considering raising prices for its Chip on Wafer on Substrate (CoWoS) advanced packaging technology by as much as 20%, according to Trendforce, citing supply chain sources and local media. The increase, driven by strained capacity amid surging AI demand and longer delivery times for chipmaking tools, would mark a significant shift in the cost structure of AI hardware.

TSMC is weighing a price increase of up to 20% for its CoWoS advanced packaging technology, according to a Trendforce report citing supply chain sources and local media. CoWoS, which combines logic dies and high-bandwidth memory (HBM) stacks in a single package, is already one of the tightest links in the AI supply chain. TSMC has not yet confirmed the report.

The pressure stems from escalating demand for AI accelerators. Nvidia's Blackwell chips pair two large GPU dies with eight HBM3E stacks, and upcoming Rubin and Rubin Ultra designs are expected to push integration further, increasing pressure on packaging and the supply chain. Testing has also become a bottleneck: Blackwell reportedly takes three to four times longer to test than Nvidia's previous-generation Hopper, while Rubin could require as much as seven times longer. Server CPUs and custom ASICs are also competing for packaging capacity.

Equipment lead times have reportedly stretched from three to six months to as long as eight months, prompting TSMC to place this year's equipment orders at existing prices rather than negotiating discounts or extra features, a departure from its usual approach. The company is also broadening its supply chain; earlier this month, GlobalFoundries agreed to produce silicon interposers for CoWoS in the U.S. under a five-year contract worth $2 billion, with production expected to ramp up in the first half of 2028. However, interposers are only one part of the packaging flow, so the agreement alone will not eliminate shortages.

TSMC is also reportedly considering broader price increases for 2027, with wafer prices on advanced process technologies expected to rise by 5% to 10%. Customers using 2nm and 3nm-class nodes could face the steepest hikes, and those seeking capacity beyond their original allocations may pay premiums of up to 25%. Industry estimates cited by Trendforce put TSMC's monthly capacity at over 106,000 wafers in 2026, with a target of 227,000 wafers in 2027.

The potential cost increases are likely to push up the price of AI hardware, with some of the burden expected to pass down the supply chain.

Analysis

Why This Matters

AI hardware costs could rise significantly. A 20% increase in CoWoS packaging and additional wafer price hikes could translate into more expensive AI accelerators and data center equipment.
Capacity constraints could slow AI adoption. With longer testing times and equipment lead times, meeting demand for advanced chips may become harder, potentially affecting AI product releases.
The price increases may ripple through the supply chain, affecting chip designers, server manufacturers, and ultimately customers.

Background

TSMC is the world's largest contract chipmaker and a key supplier of advanced packaging for AI accelerators. CoWoS technology is critical for high-bandwidth memory integration, and demand has surged with the rise of generative AI. The company has been expanding production capacity to keep pace, but bottlenecks in packaging and testing, alongside longer tool delivery times, have created strain. TSMC has previously noted unprecedented demand acceleration, with equipment needs almost doubling in six months.

Key Perspectives

TSMC (via Trendforce report): The company is reportedly considering the price increase due to capacity strain and longer tool lead times, and has placed equipment orders at existing prices to prioritize timely delivery.
TSMC deputy co-COO Cliff Hou: Said that by July, the company's expected equipment needs had reached 1.9 times its original estimate as AI demand accelerated, noting "we have never seen the demand increase that much, that frequency of changes."
Trendforce (industry estimates): Project TSMC's monthly capacity to grow from over 106,000 wafers in 2026 to 227,000 in 2027, reflecting efforts to keep pace with demand.

What to Watch

Whether TSMC officially confirms the price increase and its final scale.
The impact on Nvidia's Blackwell and Rubin launch timelines and pricing.
Whether the GlobalFoundries interposer agreement and other supply chain expansions can ease packaging bottlenecks before 2028.
