Contract chipmaker Powerchip Semiconductor Manufacturing Corp (力積電子) yesterday launched a new 12-inch fab, tapping into advanced chip-on-wafer-on-substrate (CoWoS) packaging technology to support rising demand for artificial intelligence (AI) devices.
Powerchip is to offer interposers, one of three parts in CoWoS packaging technology, with shipments scheduled for the second half of this year, Powerchip chairman Frank Huang (黃崇仁) told reporters on the sidelines of a fab inauguration ceremony in the Tongluo Science Park (銅鑼科學園區) in Miaoli County yesterday.
“We are working with customers to supply CoWoS-related business, utilizing part of this new fab’s capacity,” Huang said, adding that Powerchip intended to bridge the supply gap left by Taiwan Semiconductor Manufacturing Co (TSMC, 台積電). “Our products are in the process of verification.”

TSMC has said it plans to more than double its CoWoS capacity by the end of this year, which is still not able to meet customers’ AI demand. An insufficient supply of interposers is considered the bottleneck of TSMC’s CoWoS packaging solutions for Nvidia Corp’s AI chips.
Powerchip last month raised its capital spending by 28 percent for this year to NT$32 billion (US$984.7 million), from a previous estimate of NT$25 billion, as it plans to add manufacturing capacity for CoWoS and wafer-on-wafer packaging technologies.
The company’s new Tongluo fab, dubbed P5 fab, is to utilize 55-nanometer, 40-nanometer and 28-nanometer technologies to make OLED panel driver ICs and Wi-Fi chips initially, in addition to AI-related products.
Powerchip has invested about NT$80 billion in the new fab facilities and manufacturing equipment with an initial capacity of 50,000 12-inch wafers per month, it said.
The chipmaker plans to add another 50,000 12-inch wafers in capacity and upgrade to 22-nanometer technology based on its second-phase development plan, it said. Total investment in the fab would cost NT$300 billion, it added.
“The launch of the Tongluo fab comes at a time when the world’s integrated device manufacturers and chip designers are reconfiguring production resilience amid geopolitical conflicts,” Huang said. “This fab will satisfy major customers’ needs for building a resilient supply chain outside China. Not to mention the booming demand for AI-related applications.”
The new fab would significantly boost the company’s revenue, he said.
With AI enabling more applications and user cases, the Taiwanese semiconductor industry would play a more essential role in the world’s rapidly changing industrial environment, President Tsai Ing-wen (蔡英文) said at the opening ceremony.
Tsai attended the ground-breaking ceremony of the fab three years ago.
The semiconductor industry is a key driving force for the nation’s economy and industrial innovation, Tsai said. Last year, Taiwan’s semiconductor companies generated NT$4.3 trillion in production value, with more than 250,000 participants in the industry, she said.
Powerchip reported a fourth-straight quarterly loss for last quarter of NT$439 million. That was an improvement from losses of NT$2.11 billion in the final quarter of last year, it said, adding that it expects the quarterly losses to shrink further for the rest of the year.
SEEKING CLARITY: Washington should not adopt measures that create uncertainties for ‘existing semiconductor investments,’ TSMC said referring to its US$165 billion in the US Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) told the US that any future tariffs on Taiwanese semiconductors could reduce demand for chips and derail its pledge to increase its investment in Arizona. “New import restrictions could jeopardize current US leadership in the competitive technology industry and create uncertainties for many committed semiconductor capital projects in the US, including TSMC Arizona’s significant investment plan in Phoenix,” the chipmaker wrote in a letter to the US Department of Commerce. TSMC issued the warning in response to a solicitation for comments by the department on a possible tariff on semiconductor imports by US President Donald Trump’s
‘FAILED EXPORT CONTROLS’: Jensen Huang said that Washington should maximize the speed of AI diffusion, because not doing so would give competitors an advantage Nvidia Corp cofounder and chief executive officer Jensen Huang (黃仁勳) yesterday criticized the US government’s restrictions on exports of artificial intelligence (AI) chips to China, saying that the policy was a failure and would only spur China to accelerate AI development. The export controls gave China the spirit, motivation and government support to accelerate AI development, Huang told reporters at the Computex trade show in Taipei. The competition in China is already intense, given its strong software capabilities, extensive technology ecosystems and work efficiency, he said. “All in all, the export controls were a failure. The facts would suggest it,” he said. “The US
The government has launched a three-pronged strategy to attract local and international talent, aiming to position Taiwan as a new global hub following Nvidia Corp’s announcement that it has chosen Taipei as the site of its Taiwan headquarters. Nvidia cofounder and CEO Jensen Huang (黃仁勳) on Monday last week announced during his keynote speech at the Computex trade show in Taipei that the Nvidia Constellation, the company’s planned Taiwan headquarters, would be located in the Beitou-Shilin Technology Park (北投士林科技園區) in Taipei. Huang’s decision to establish a base in Taiwan is “primarily due to Taiwan’s talent pool and its strength in the semiconductor
French President Emmanuel Macron has expressed gratitude to Hon Hai Precision Industry Co (鴻海精密) for its plan to invest approximately 250 million euros (US$278 million) in a joint venture in France focused on the semiconductor and space industries. On his official X account on Tuesday, Macron thanked Hon Hai, also known globally as Foxconn Technology Group (富士康科技集團), for its investment projects announced at Choose France, a flagship economic summit held on Monday to attract foreign investment. In the post, Macron included a GIF displaying the national flag of the Republic of China (Taiwan), as he did for other foreign investors, including China-based
