Taiwanese prosecutors detain three over alleged TSMC chip secret theft

/in /tarafından

Taiwanese prosecutors have detained three individuals — two current TSMC employees and one former staff member surnamed Chen — over allegations of stealing trade secrets from Taiwan Semiconductor Manufacturing Co (TSMC), the world’s largest chip foundry. The detentions took place late last month following a TSMC internal investigation that uncovered unauthorized access to company information.

Two additional suspects were released on bail, while another was released without bail. Authorities suspect the detained individuals of violating Taiwan’s national security law, though no detailed identities have been disclosed.

TSMC stated it initiated legal action and disciplinary measures against those involved after routine monitoring detected suspicious activity. The company’s early detection system prompted swift internal inquiries, leading to the identification of personnel linked to the breach. The matter is now under judicial review, preventing further public disclosure from TSMC.

According to Nikkei Asia, the case involves attempts by several former employees to obtain highly sensitive information related to TSMC’s 2-nanometer chip technology — considered the industry’s most advanced in density and energy efficiency. Investigations have not yet determined whether the stolen information was transferred to external parties or the full scope of the leak.

Taiwanese media outlet United Daily News reported that prosecutors also searched offices of Japanese chip equipment supplier Tokyo Electron, though both the company and prosecutors declined comment.

TSMC, a critical supplier to Nvidia, Apple, and Qualcomm, reiterated its zero-tolerance policy on trade secret violations, vowing to prosecute offenders to the fullest extent of the law.

Shares of Key Chip Suppliers Jump as U.S. Considers Milder China Sanctions

/in /tarafından

Shares of global semiconductor equipment suppliers surged on Thursday following reports that the U.S. is revising its proposed sanctions on China’s chip industry, potentially implementing less restrictive measures than previously planned.

ASML, a Dutch semiconductor equipment manufacturer, saw its shares rise by approximately 4.3% in early trading in Europe. Similarly, Japan’s Tokyo Electron saw a more than 6% increase in its share price.

According to a Bloomberg report, the U.S. government is contemplating new restrictions on the sale of semiconductor equipment and AI memory chips to China, but these measures are expected to be less severe than earlier proposals.

The U.S. Commerce Department’s Bureau of Industry and Security did not provide an immediate comment regarding the Bloomberg article.

One significant shift in the proposed measures is the decision not to add certain Chinese companies to the U.S. export blacklist, known as the Entity List. Among the companies not affected is ChangXin Memory Technologies, a Chinese memory manufacturer that competes with major global players like SK Hynix and Samsung.

For ASML, analysts at Jefferies noted that the company had previously forecast a 30% revenue decline from China next year due to restrictions. However, the exclusion of ChangXin from the export blacklist could result in a smaller-than-expected decline in ASML’s Chinese sales for 2024.

 

SK Hynix Spurs Rally in Asian Semiconductor Stocks with Mass Production of Advanced AI Chip

SK Hynix shares surged by over 9% on Thursday after the South Korean chipmaker announced the mass production of a new high-bandwidth memory (HBM) chip designed for AI applications. The company revealed that the HBM3E chip, the first 12-layer version of its kind, will be ready for delivery by the end of the year. This updated chip boasts a 36 GB capacity, marking a 50% increase from the previous 8-layer version, all while maintaining the same physical thickness.

SK Hynix has positioned itself as a key player in the AI memory chip market, supplying HBM chips to major tech firms like Nvidia. With the new 12-layer HBM3E chip, the company seeks to solidify its dominance in the space, offering advanced solutions for high-end generative AI workloads.

HBM chips are dynamic random access memory (DRAM) components that are stacked vertically, allowing for more compact designs and reduced power consumption. The global HBM market is currently dominated by SK Hynix, Micron Technology, and Samsung Electronics.

Micron Technology also made headlines by issuing better-than-expected revenue and profit forecasts for its fiscal first quarter, citing strong demand for HBM chips. Micron expects $8.7 billion in revenue and profits of $1.74 per share, surpassing market estimates. This positive outlook, coupled with SK Hynix’s announcement, led to a rally in Asian semiconductor stocks.

In Japan, Tokyo Electron’s shares rose 7%, and Advantest climbed 5%, while Samsung Electronics saw a 3% gain. The South Korean Kospi index also responded positively, increasing by 2% as the sector benefitted from these developments.
