➀ The US Commerce Department has requested Nvidia to investigate how its chips entered China over the past year.

➁ Nvidia has asked Supermicro Computer and Dell Technologies to inspect Southeast Asian clients, as their server products use Nvidia's AI chips.

➂ Nvidia emphasizes compliance with export restrictions and denounces any illegal sales.

➃ Some individuals are suspected of copying serial numbers from Supermicro's servers and connecting them to other servers they have access to.

➄ China's State Administration for Market Regulation has launched an investigation against Nvidia for suspected violations of the Anti-Monopoly Law.

➅ Nvidia's acquisition of Mellanox, a network interconnect product company, has raised concerns about potential monopolistic practices.

➆ The US government has imposed restrictions on the export of advanced AI chips to China, including Nvidia's A100 and H100.

➇ In response to US restrictions, China has taken countermeasures, including restricting exports of certain materials to the US.

➀ The US government has imposed export controls on high-bandwidth memory (HBM) and semiconductor equipment to China to prevent China from acquiring key components for AI development.

➁ The US Commerce Department's Bureau of Industry and Security (BIS) announced the addition of specific HBM products to the list of controlled items.

➂ The controls apply to products with memory bandwidth density of over 2 gigabytes per square millimeter per second.

➀ ASML's overlay tool (YieldStar) and OPC mask making software (Tachyon suite) sales impacted by new export controls;

➁ Updated export control regulations include metrology and software in restricted technologies list;

➂ Additional fab locations in China added to US restrictions list;

➃ Commerce issued three new documents clarifying new export control rules;

➄ China's semiconductor phone book copied-pasted in the new export control list;

➅ ERC added 106 entities to the Entity List.

➀ Current Western export controls have slowed China's progress in advanced logic, but are not perfect or infallible.

➁ Loopholes in restrictions include offshore manufacturing, end-use workarounds, and renaming/reclassifying technologies.

➂ Huawei's fab network poses a national security concern, exploiting sanctions and advancing domestic semiconductor supply chains.

➃ WFE suppliers' lobbying for relaxed controls is refuted by strong business performance and long-term market share impacts from domestic Chinese firms.

➄ Suggestions for improving export controls include expanding the entity list, aligning ally restrictions, tightening supply chain restrictions, and improving enforcement.

➀ TSMC stopped shipping chips to a specific customer in mid-October after discovering the chips were used in Huawei products;

➁ It is unclear whether the customer represents Huawei and where its headquarters are located;

➂ The incident provides new clues to recent reports, including those from The Information, which claimed the US recently contacted TSMC about producing chips for a blacklisted Chinese company;

➃ Huawei has relied on Semiconductor Manufacturing International Corporation (SMIC) for its chip production, including the 7-nanometer chips used in its smartphones last August;

➄ TSMC stopped shipping chips to Huawei after September 15, 2020, and reiterated this point when asked about TechInsights' report;

➅ TSMC and Huawei representatives refused to comment on the reports;

➆ The US Department of Commerce acknowledged that there may have been violations of US export control regulations;

➇ TSMC stated that it is a law-abiding company committed to complying with all applicable regulations, including export control regulations;

➈ Huawei stated that it has not produced any chips through TSMC since the implementation of the Foreign Direct Product Rule (FDPR) in 2020;

➉ Taiwan's Minister of Economic Affairs stated that Taiwan respects the US' export control measures and will communicate fully with TSMC;

➊ The US Bureau of Industry and Security (BIS) had a meeting with TSMC executives in October to discuss supply chain issues, including whether third-party distributors can provide restricted technology to China.

➀ The U.S. Department of Commerce is investigating TSMC for potentially producing AI or smartphone chips for Huawei.

➁ TSMC responds that the company is a law-abiding enterprise committed to complying with all applicable rules and regulations, including export controls.

➂ There is a possibility that Huawei may have purchased chips from TSMC under different company names or through intermediary companies, and it is being investigated whether TSMC conducted due diligence on customers (KYC) when accepting orders.

➀ ASML, a major semiconductor manufacturing equipment company, has lowered its earnings forecast, impacting global semiconductor stocks.

➁ ASML's revenue from the Chinese market, which accounted for about 50% of its overall revenue, is expected to decline to around 20% next year due to US export controls.

➂ The semiconductor industry is facing weak demand, particularly for AI以外的 products, and concerns about the impact of US export controls are rising.
