Vanguard International Semiconductor Corp (世界先進), a supplier of display driver ICs and power management chips, yesterday said it would not join the enthusiasm for global 12-inch capacity expansion, given budget pressures and overcapacity risks.
The Hsinchu-based chipmaker said that it is expanding capacity to catch up with demand by prioritizing 8-inch wafer capacity at its Fab 3 in Taiwan.
The fab will add 24,000 wafers to its existing capacity by the end of next year, it said.

Additionally, its newly acquired Fab 5 will be ready for deployment in the spring next year for further increases in 8-inch wafer supply, it said.
“We do not have any plan to build a 12-inch fab any time soon,” Vanguard chairman Fang Leuh (方略) said. “It should be reasonable for us to look at the possibility of building a 12-inch fab to expand capacity in the future, given scant accessibility to 8-inch wafer manufacturing equipment and high costs.”
Based on the company’s calculations, 8-inch wafer manufacturing equipment costs have more than doubled over the past two years.
Vanguard said it is making a long-term agreement with customers, and accepting prepayments for newly built 8-inch wafers to absorb a surge in manufacturing costs.
There is a risk of short-term supply gluts to consider, Fang said. Chipmakers are investing in new 12-inch fabs with an aim to begin production in 2023 or 2024, and it is unknown if high-performance computing devices and 5G-related applications would consume that capacity, he said.
Fang said that Vanguard would not follow Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) in expanding its footprint in Kaohsiung.
TSMC last week said it plans to build a new 12-inch fab in the southern port city to make 7-nanometer and 28-nanometer chips in 2024 to cope with rising demand.
Demand for 8-inch wafers could outpace supply over the next five years, as supply is expected to grow at an annual compound rate of lower than 3 percent from next year to 2026, Vanguard’s estimates show.
Fang said that it is optimistic about next year’s business outlook, following a strong showing this year.
“Demand looks very strong in the first half of next year. There is no sign of demand subsiding,” he said, adding that Vanguard plans to recruit hundreds of workers to support capacity expansion next year.
MARKET LEADERSHIP: Investors are flocking to Nvidia, drawn by the company’s long-term fundamntals, dominant position in the AI sector, and pricing and margin power Two years after Nvidia Corp made history by becoming the first chipmaker to achieve a US$1 trillion market capitalization, an even more remarkable milestone is within its grasp: becoming the first company to reach US$4 trillion. After the emergence of China’s DeepSeek (深度求索) sent the stock plunging earlier this year and stoked concerns that outlays on artificial intelligence (AI) infrastructure were set to slow, Nvidia shares have rallied back to a record. The company’s biggest customers remain full steam ahead on spending, much of which is flowing to its computing systems. Microsoft Corp, Meta Platforms Inc, Amazon.com Inc and Alphabet Inc are
Luxury fashion powerhouse Prada SpA has acknowledged the ancient Indian roots of its new sandal design after the debut of the open-toe footwear sparked a furor among Indian artisans and politicians thousands of miles from the catwalk in Italy. Images from Prada’s fashion show in Milan last weekend showed models wearing leather sandals with a braided design that resembled handmade Kolhapuri slippers with designs dating back to the 12th century. A wave of criticism in the media and from lawmakers followed over the Italian brand’s lack of public acknowledgement of the Indian sandal design, which is named after a city in the
The US overtaking China as Taiwan’s top export destination could boost industrial development and wage growth, given the US is a high-income economy, an economist said yesterday. However, Taiwan still needs to diversify its export markets due to the unpredictability of US President Donald Trump’s administration, said Chiou Jiunn-rong (邱俊榮), an economics professor at National Central University. Taiwan’s exports soared to a record US$51.74 billion last month, driven by strong demand for artificial intelligence (AI) products and continued orders, with information and communication technology (ICT) and audio/video products leading all sectors. The US reclaimed its position as Taiwan’s top export market, accounting for
NEW MODELS: AI researchers are facing challenges in managing deceptive behaviors, with limited regulation and testing, as the race for advanced models intensifies The world’s most advanced artificial intelligence (AI) models are exhibiting troubling new behaviors — lying, scheming and even threatening their creators to achieve their goals. In one particularly jarring example, under threat of being unplugged, Anthropic PBC’s latest creation, Claude 4, lashed back by blackmailing an engineer and threatening to reveal an extramarital affair. Meanwhile, ChatGPT creator OpenAI’s o1 tried to download itself onto external servers and denied it when caught red-handed. These episodes highlight a sobering reality: More than two years after ChatGPT shook the world, AI researchers still do not fully understand how their own creations work. Yet the race to
