Taiwan Semiconductor Manufacturing Co. reported record revenue for the June quarter, the latest signal that demand for artificial-intelligence chips shows no sign of cooling. June sales jumped 68 percent from a year earlier, and the company’s second-quarter revenue rose about 36 percent from the first quarter, according to Bloomberg’s tally, pushing the total to a new high.
The numbers arrived on the same day Taiwan’s economy minister confirmed that TSMC will add two more advanced packaging plants at the Chiayi Science Park’s second phase, a move aimed at easing one of the industry’s most stubborn bottlenecks. The plants will expand capacity for CoWoS, the chip-on-wafer-on-substrate technology that packages the memory and compute dies used in AI accelerators. Demand for CoWoS has outpaced supply for two years, and every major AI chip designer has been competing for the limited capacity.
The packaging shortage has become the quiet constraint on the AI boom. Chip fabrication has attracted most of the attention, but the final assembly of AI processors, which stacks high-bandwidth memory beside the compute die, is where the physical limits show up. TSMC has been expanding packaging capacity at its main hubs in Taiwan, and the Chiayi additions are part of that program.
The revenue record is built on the same demand. The 68 percent jump in June sales reflects shipments of advanced-node processors to customers who cannot get enough packaging capacity, a sign that the constraint is supply, not orders. Analysts said the combination of record revenue and new packaging investment points to a demand curve that is still rising, with the company’s largest customers planning bigger orders for the second half of the year.
The expansion comes with costs attached. Advanced packaging plants are expensive to build, and TSMC has been lifting its capital spending plans to keep pace with demand. The company has also had to allocate land, power and water, all of which are scarce in Taiwan. The Chiayi site, in the south of the island, was chosen partly because the region has room to grow and access to the grid improvements the government is financing.
The economics of packaging have quietly improved alongside the demand. CoWoS capacity commands premium prices, and the margin profile of the packaging business has moved closer to that of leading-edge wafer fabrication. That has made the expansion more attractive internally, executives have said, and it gives TSMC a second profitable pillar alongside its core foundry business.
The broader question is how long the shortage lasts. TSMC has told customers it is adding packaging capacity on a multi-year schedule, and the Chiayi plants will not come online all at once. In the meantime, the company is also developing next-generation packaging technologies, including more advanced variants that stack dies more tightly. Each step up the packaging curve buys the industry another year of AI compute growth.
The record quarter also carries a message for investors who have worried that the AI cycle is peaking. A 68 percent year-over-year jump in the most recent month is not the profile of a demand curve rolling over. The company’s guidance, embedded in the monthly sales reports, points to continued growth into the third quarter, and its customer list reads like a roster of the AI industry’s largest spenders.
The packaging build-out is also a competitive story. Rivals including Samsung Electronics and Intel have made inroads in advanced packaging, and a growing crowd of specialty firms is chasing the same customers. TSMC’s answer is scale: the Chiayi additions, combined with its other sites, are meant to keep the company so far ahead in capacity that customers have no reason to qualify a second supplier. The strategy has worked in wafer fabrication, and the company is applying it to packaging with the same playbook.
The market’s reaction to the record quarter was muted by design. TSMC’s shares have already priced in strong growth, and the company’s stock tends to move on guidance for the next quarter rather than on the confirmation of a good one. Investors are watching the September revenue reports for signs of whether the third-quarter trajectory matches the second. The packaging expansion, by contrast, is a multi-year story, and its payoff will show up in the company’s margins and market share well after the current cycle of monthly records has been logged.
What could break the run is not demand but logistics: power, land, equipment and the supply of advanced materials all feed into packaging output. The Chiayi expansion addresses the land and power questions. Equipment lead times remain long, and TSMC is competing with rivals for the same toolmakers. For now, the company’s answer to every constraint has been the same one it applied to the chip shortage a generation ago: build more, and build faster.
The record is likely to be followed by another one. With AI order books full and packaging capacity still scarce, TSMC’s growth is being set by how quickly it can open plants, not by how many chips its customers want. That is a good position to be in, and a difficult one to manage. The Chiayi announcement says TSMC intends to keep managing it the same way it always has: with concrete, and with enough of it.
