US Secretary of Commerce Howard Lutnick’s call for a “50-50” split in semiconductor production could shift Taiwan's “silicon shield” toward a shared Taiwan-US resilience, a semiconductor industry expert said yesterday.
Lutnick on Sunday told NewsNation that he is pushing Taiwan to adopt a “50-50” plan, in which Taiwan and the US each produce 50 percent of the chips used by the US market.
The concept of the “silicon shield” arose because Taiwan has long held more than 90 percent of global advanced chip capacity, which could help deter a Chinese invasion, Taiwan Institute of Economic Research researcher Arisa Liu (劉佩真) said.

However, the US has said that sufficient domestic chip production is needed to safeguard Taiwan, warning that if Taiwan’s output were disrupted by a conflict, Washington would lack the chips essential for military and economic operations, Liu said.
This position indicates that the US is effectively redefining the “silicon shield” from being “Taiwan only” to a shared Taiwan-US resilience, she said.
The US sees achieving a certain level of domestic chip self-sufficiency, or at least a “50-50” shared production arrangement, as essential to shouldering its protective responsibilities without concern, Liu said.
Washington could pressure Taiwan Semiconductor Manufacturing Co (TSMC) to speed up its construction of US fabs and expand investment in the US, she said, adding that other supply chain companies could face similar pressures.
TSMC is investing US$65 billion to build three advanced wafer fabs in Arizona, the first of which began commercial production late last year.
In March, TSMC pledged to invest an additional US$100 billion in Arizona over the next few years to build three more fabs, two chip packaging plants and one research and development (R&D) center.
For Taiwan, the main concern should be safeguarding its technological edge and intellectual property while balancing domestic R&D needs with the demand for talent at overseas fabs, Liu said.
Since being elected, US President Donald Trump has pushed to get more semiconductor manufacturing in the US, threatening huge tariffs on chip-importing companies that do not manufacture all of the chips they use in the US.
Separately, the Ministry of Economic Affairs yesterday said that Taiwan’s trade talks with the US are being coordinated by the Executive Yuan and are ongoing, without providing any details.
Asked about Lutnick’s remarks, the ministry said that it cannot comment on the US' position, but the matter would be handled cautiously.
A magnitude 6.1 earthquake struck off the coast of Yilan County at 8:39pm tonight, the Central Weather Administration (CWA) said, with no immediate reports of damage or injuries. The epicenter was 38.7km east-northeast of Yilan County Hall at a focal depth of 98.3km, the CWA’s Seismological Center said. The quake’s maximum intensity, which gauges the actual physical effect of a seismic event, was a level 4 on Taiwan’s 7-tier intensity scale, the center said. That intensity level was recorded in Yilan County’s Nanao Township (南澳), Hsinchu County’s Guansi Township (關西), Nantou County’s Hehuanshan (合歡山) and Hualien County’s Yanliao (鹽寮). An intensity of 3 was
Instead of focusing solely on the threat of a full-scale military invasion, the US and its allies must prepare for a potential Chinese “quarantine” of Taiwan enforced through customs inspections, Stanford University Hoover fellow Eyck Freymann said in a Foreign Affairs article published on Wednesday. China could use various “gray zone” tactics in “reconfiguring the regional and ultimately the global economic order without a war,” said Freymann, who is also a nonresident research fellow at the US Naval War College. China might seize control of Taiwan’s links to the outside world by requiring all flights and ships entering or leaving Taiwan
The first of 10 new high-capacity trains purchased from South Korea’s Hyundai Rotem arrived at the Port of Taipei yesterday to meet the demands of an expanding metro network, Taipei Rapid Transit Corp (TRTC) said yesterday. The train completed a three-day, 1,200km voyage from the Port of Masan in South Korea, the company said. Costing NT$590 million (US$18.79 million) each, the new six-carriage trains feature a redesigned interior based on "human-centric" transportation concepts, TRTC said. The design utilizes continuous longitudinal seating to widen the aisles and optimize passenger flow, while also upgrading passenger information displays and driving control systems for a more comfortable
Taiwan's first indigenous defense submarine, the SS-711 Hai Kun (海鯤, or Narwhal), departed for its 13th sea trial at 7am today, marking its seventh submerged test, with delivery to the navy scheduled for July. The outing also marked its first sea deployment since President William Lai (賴清德) boarded the submarine for an inspection on March 19, drawing a crowd of military enthusiasts who gathered to show support. The submarine this morning departed port accompanied by CSBC Corp’s Endeavor Manta (奮進魔鬼魚號) uncrewed surface vessel and a navy M109 assault boat. Amid public interest in key milestones such as torpedo-launching operations and overnight submerged trials,
