United Microelectronics Corp (UMC, 聯電) yesterday saw its share price soar to close at a two-week high on reports that Washington is looking to ban Semiconductor Manufacturing International Corp (SMIC, 中芯) amid an escalating US-China trade dispute.
UMC shares jumped 9.79 percent to NT$23.55, after Reuters on Friday last week reported that the US Ministry of Defense has proposed working with other agencies to determine whether to place SMIC on a trade blacklist because of its relationship with the Chinese military.

Turnover of UMC shares hit 97.93 million yesterday, the biggest since Monday last week.
SMIC shares tumbled 22.88 percent to end at H$18.24 on the Hong Kong Stock Exchange.
“In our view, the US curbs will have a positive impact on Taiwan’s semiconductor industry,” if Washington were to put SMIC on the blacklist, Yuanta Securities Investment Consulting Co (元大投顧) said in a note yesterday.
Yuanta expects “UMC to be a major beneficiary from the US’ potential ban,” given the similarities in revenue scale and foundry technology offerings of the two companies, the note said.
UMC ranked as the world’s fourth-biggest foundry last quarter, with revenue of US$1.44 billion, while SMIC had US$941 million in revenue, according to the statistics compiled by market researcher TrendForce Corp (集邦科技).
Both companies offer 14 nanometers as their most advanced process technology, but SMIC generates a large part of its revenue from less advanced chips, TrendForce said.
With Beijing’s support, SMIC is striving to move to next-generation process technologies to catch up with bigger rivals Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) and Samsung Electronics Co. However, the US restrictions would be an obstacle to SMIC’s ambition due to a scant supply of key manufacturing equipment, Yuanta said.
Novatek Microelectronics Corp (聯詠科技), which supplies chips that control flat-panel displays, would be another beneficiary and could see a rebound in its share price, as the US ban would make it difficult for SMIC to tap into the driver IC market, Yuanta said.
Novatek shares have plunged about 15 percent since media reports last month that Huawei Technologies Co (華為) planned to team up with SMIC to make inroads into the driver IC market.
UMC, Vanguard International Semiconductor Corp (世界先進) and GlobalFoundries Inc are likely to receive orders transferred from SMIC if the Trump administration further tightened its grip on SMIC and other Chinese semiconductor companies, Jih Sun Securities Investment Consulting Co (日盛投顧) said in a research note.
Since UMC and Vanguard are running their 8-inch fabs at almost full capacity, they could see an uptick in chip prices amid supply constraints, while UMC and TSMC could see an increase in demand for less advanced chips made by their 12-inch fabs, Jih Sun said.
TSMC and Novatek shares dropped 0.7 percent and 0.82 percent to NT$426 and NT$241 respectively in Taipei trading yesterday. Vanguard shares climbed 2.88 percent to NT$96.50.
SEMICONDUCTOR SERVICES: A company executive said that Taiwanese firms must think about how to participate in global supply chains and lift their competitiveness Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday said it expects to launch its first multifunctional service center in Pingtung County in the middle of 2027, in a bid to foster a resilient high-tech facility construction ecosystem. TSMC broached the idea of creating a center two or three years ago when it started building new manufacturing capacity in the US and Japan, the company said. The center, dubbed an “ecosystem park,” would assist local manufacturing facility construction partners to upgrade their capabilities and secure more deals from other global chipmakers such as Intel Corp, Micron Technology Inc and Infineon Technologies AG, TSMC said.

EXPORT GROWTH: The AI boom has shortened chip cycles to just one year, putting pressure on chipmakers to accelerate development and expand packaging capacity Developing a localized supply chain for advanced packaging equipment is critical for keeping pace with customers’ increasingly shrinking time-to-market cycles for new artificial intelligence (AI) chips, Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) said yesterday. Spurred on by the AI revolution, customers are accelerating product upgrades to nearly every year, compared with the two to three-year development cadence in the past, TSMC vice president of advanced packaging technology and service Jun He (何軍) said at a 3D IC Global Summit organized by SEMI in Taipei. These shortened cycles put heavy pressure on chipmakers, as the entire process — from chip design to mass

NO BREAKTHROUGH? More substantial ‘deliverables,’ such as tariff reductions, would likely be saved for a meeting between Trump and Xi later this year, a trade expert said China launched two probes targeting the US semiconductor sector on Saturday ahead of talks between the two nations in Spain this week on trade, national security and the ownership of social media platform TikTok. China’s Ministry of Commerce announced an anti-dumping investigation into certain analog integrated circuits (ICs) imported from the US. The investigation is to target some commodity interface ICs and gate driver ICs, which are commonly made by US companies such as Texas Instruments Inc and ON Semiconductor Corp. The ministry also announced an anti-discrimination probe into US measures against China’s chip sector. US measures such as export curbs and tariffs
