Tokyo Electron sacks Taiwan employee over TSMC tech leak
Tokyo Electron
said Thursday it has fired an employee at its Taiwan subsidiary over their alleged involvement in a
trade secret leak
at Taiwanese chipmaking giant
TSMC
.
The Japanese firm issued a statement after media reports said Taiwanese authorities had searched its Hsinchu office as part of a probe into the breach.
Six people were arrested after TSMC discovered the leak involving "national core technology" in July, Taiwan's High Prosecutors Office said this week.
TSMC is the world's largest contract chip manufacturer and counts
Nvidia
and
Apple
among its clients.
Taiwanese media have reported that the leaked information was related to TSMC's most advanced 2-nanometre
chip technology
.
A former employee and two current TSMC staff members have been detained, while two other employees were released on bail and another freed without any conditions, prosecutors said.
The sacked Tokyo Electron staff member previously worked for TSMC and is among those detained, a source with knowledge of the investigation told AFP.
Tokyo Electron is a major producer of chipmaking equipment used by TSMC, winning the 2024 TSMC Excellent Performance Award for both "technology collaboration and production support".
Another client is Japanese chipmaker Rapidus, which is building a plant in Hokkaido to make
2-nanometre chips
.
Rapidus chairman Tetsuro Higashi is a former president of Tokyo Electron.
Tokyo Electron said it sacked its staff member after they were "confirmed to be involved in an incident announced by Taiwanese judicial authorities on August 5".
"The company has terminated their employment and is fully cooperating with the investigation by Taiwanese judicial authorities," Tokyo Electron said.
"An internal investigation has revealed no leaks of confidential information so far."
In a statement, TSMC said it had taken "strict disciplinary actions against the personnel involved" in the "potential trade secret leaks".
TSMC did not provide details about the technology involved in the suspected leaks.

iPhone 17 Pro launch date and price in India is…
Apple is gearing up for its major launch of the year with the iPhone 17 series, expected in the first week of September 2025. While no official announcement has been made, Bloomberg's Mark Gurman suggests the event could take place on September 9 or 10. The new lineup will likely include the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and a new slim model, the iPhone 17 Air, which replaces the iPhone 17 Plus. Alongside the phones, Apple is also anticipated to unveil the Apple Watch Series 11, Apple Watch SE 3, and Apple Watch Ultra 3. Apple iPhone 17 launch event in 2025 could take place on September 9 or 10. (Majin BU/ X) In India, pricing is expected to start at around ₹1,45,990 for the iPhone 17 Pro and ₹1,64,990 for the iPhone 17 Pro Max. Pricing details for the iPhone 17 Air and the standard model remain to be confirmed. Also read: iPhone 16e quick review: Compact but powerful contender The iPhone 17 series is expected to maintain display sizes similar to the current models. The Pro and Pro Max should keep their 6.3-inch and 6.9-inch displays, while the iPhone 17 Air will sit between these two in size. The standard iPhone 17 might grow to 6.3 inches, matching the Pro. Earlier reports suggested the iPhone 17 Air would be a premium device priced above the Pro Max, but current sources indicate it will be positioned as a mid-range option—less expensive than the Pro models but more costly than the standard iPhone 17. This positions it as a direct successor to the 'Plus' model, offering a balance of size and price. All four models are expected to receive ProMotion technology with a 120Hz refresh rate for smoother scrolling and video playback, previously exclusive to Pro models. This will be enabled by LTPO OLED panels. Although LTPO displays support always-on screens, it remains uncertain whether this feature will be available on all models or remain limited to the Pro versions.

This would create a half-glass, half-aluminium build, improving durability. The current square camera bump may be replaced by a horizontal pill-shaped design, which the iPhone 17 Air is also expected to adopt. Powering the series is expected to be Apple's A19 Pro chip, built on TSMC's latest 3nm process. This chip promises better speed and power efficiency. For the first time, iPhones might come with up to 12GB of RAM, allowing smoother multitasking and support for advanced AI features under Apple Intelligence. Also read: Samsung Galaxy S25 Ultra review: Almost the perfect Android flagship Camera upgrades are significant across the lineup. All models could see a jump from the 12MP front camera in the iPhone 16 series to a new 24MP sensor for sharper images and better cropping capability. The iPhone 17 Pro Max is expected to have three 48MP rear cameras—a Wide, Ultra Wide, and a Tetraprism Telephoto lens—and may support 8K video recording for the first time. The iPhone 17 Air might feature a single 48MP rear camera, while the standard iPhone 17 could come with a dual-lens setup consisting of Wide and Ultra Wide cameras. The Pro models may introduce a mechanical aperture for adjustable light intake, improving depth-of-field control—an industry first for iPhones that have traditionally used fixed apertures. They could also include dual video recording to film with front and rear cameras simultaneously, a feature popular among content creators but currently limited to third-party apps. The 5x Telephoto optical zoom will continue to be exclusive to the Pro models. The standard iPhone 17 and iPhone 17 Air will not feature Telephoto lenses or 5x zoom.

US government to take cut of Nvidia and AMD AI chip sales to China
Nvidia and Advanced Micro Devices are expected to pay the United States 15% of the money they take in from selling artificial intelligence chips to China, as part of a highly unusual financial agreement with the Trump administration. The deal, which was described by three people familiar with the agreement who spoke anonymously because they didn't have permission to discuss it publicly, comes a month after Nvidia received permission to sell a version of its artificial intelligence chips to China. While the Trump administration publicly said a month ago that it was giving the green light to Nvidia to sell an AI chip called H20 to China, it did not actually issue the licenses making those sales possible. On Wednesday, Nvidia CEO Jensen Huang met with President Donald Trump at the White House and agreed to give the federal government its 15% cut, essentially making the federal government a partner in Nvidia's business in China, said the people familiar with the deal. The Commerce Department began granting licenses for AI chip sales two days later, these people said. Though Huang has led negotiations with the White House, Nvidia isn't the only company that sells AI chips to China. AMD has an AI chip called the MI308 and in April the Trump administration also banned sales of it to the Chinese. There are few precedents for the Commerce Department agreeing to grant licenses for exports in exchange for a share of revenue. But the unorthodox payments are consistent with Trump's increasingly interventionist role in international business deals involving U.S. companies. In June, the administration approved investment by Nippon Steel, a Japanese company, in U.S. Steel in a deal that included a so-called golden share in the company, a rarely used practice where the government takes a stake in a business. The administration is also using tariffs as a stick to bring manufacturing to the United States. Last week, Trump said tech companies would have to pay a 100% tariff on semiconductors made abroad, unless they invested in the United States. The deal agreed to last week could funnel more than $2 billion to the U.S. government. Nvidia was expected to sell more than $15 billion worth of its H20 chip to China through the end of the year, and AMD was expected to sell $800 million, according to Bernstein Research. The Commerce Department, White House and AMD didn't provide comment Sunday. Ken Brown, a spokesperson for Nvidia, said the company follows the U.S. government's rules for sales abroad. 'While we haven't shipped H20 to China for months, we hope export control rules will let America compete in China and worldwide,' he said. The deal to license AI chips caused immediate outcry among national security experts who have been opposed to AI chip sales to China. They worry that the Trump administration's decision to leverage export licenses for money will encourage Beijing to pressure other companies to make similar arrangements to loosen restrictions on other technology, such as semiconductor manufacturing tools and memory chips. 'This is an own goal and will incentivize the Chinese to up their game and pressure the administration for more concessions,' said Liza Tobin, who previously served as China director at the National Security Council during the Trump and Biden administrations. 'This is the Trump playbook applied in exactly the wrong domain. You're selling our national security for corporate profits.' The Financial Times earlier reported on the deal between the chipmakers and the Trump administration. Clearing the way for selling AI chips to China was a dramatic about-face by the Trump administration, which banned their sales to China in April. The administration restricted exports of those chips because of concerns that the technology could be used to close the gap between the United States and China in the development of artificial intelligence. The administration's reversal on AI chip sales has been divisive because it has major implications for the race between the two countries to develop AI. Nvidia's chips are regarded as ideal for running some calculations that power AI and have better performance than those offered by its Chinese rival, Huawei. The Trump administration has said that it will continue to prevent China from buying Nvidia's most advanced chips. It has said that the H20 chip, which was made specifically for China and was approved for sale by the Biden administration, is less powerful than the chips the company sells to U.S. businesses and allies. 'We don't sell them our best stuff, not our second-best stuff, not even our third-best,' Commerce Secretary Howard Lutnick said during an appearance on CNBC last month. He said the goal was to stay one step ahead of China, so it would keep buying U.S. chips. Huang persuaded Trump to approve AI chip sales by arguing that preventing them would only hurt U.S. tech companies. He has said a ban would allow Huawei to dominate sales of AI chips in China, the world's largest semiconductor market, and pump the money it makes into research and development to close the gap with Nvidia, AMD and others. Instead, he urged Trump to let Nvidia and AMD compete for those sales, so that they can use the money they make there to build their businesses. 'The American tech stack should be the global standard, just as the American dollar is the standard by which every country builds on,' Huang said during a podcast recorded in July with the Special Competitive Studies Project, a think tank. But many national security officials focused on China disagree. In July, two former national security officials in the Trump administration, Matt Pottinger and David Feith, and 18 other people with a mix of national security and economics expertise wrote a letter to the administration calling its policy change 'a strategic misstep that endangers the United States' economic and military edge in artificial intelligence.' The group said that the H20 would be 'a potent accelerator of China's frontier AI capabilities, not an outdated chip.' Nvidia's wins in Washington have brought it headaches in Beijing. Late last month, China's internet regulator, the Cyberspace Administration of China, summoned Huang to a meeting over the possibility that the H20 chip could have 'backdoor security risks.' Chinese state media has discouraged companies from buying the H20 over the issue. Last week, Nvidia published a blog saying that its AI chips don't have back doors. It also condemned a congressional effort to pass a law known as the Chip Security Act, which would require it to track its chips as a way to prevent the technology from being smuggled to China. 'There is no such thing as a 'good' secret backdoor — only dangerous vulnerabilities that need to be eliminated,' the company said.

iPhone 17 and iPhone 17 Pro Max to launch next month: Every upgrade expected for Apple's most powerful phones
Apple is all set to introduce its new iPhone 17 lineup at a launch event next month. While the Cupertino-based tech giant has not yet sent invites for its biggest launch event of the year, it usually follows a pattern of unveiling new iPhones in early September — and this year should be no different. With just a few weeks left before the upcoming iPhone launches, there has been a lot of speculation around the series. The most anticipated models are the iPhone 17 Pro and iPhone 17 Pro Max, so let's take a look at all the upgrades Apple is reportedly planning for its costliest devices. If leaks are to be believed, Apple is planning to ditch the titanium frame on the iPhone 17 Pro models this year and instead switch back to an aluminium frame. The new iPhones are likely to have an aluminium frame with the back featuring a half-aluminium, half-glass finish. Apart from helping with durability, the new design would still allow wireless charging thanks to the glass section. Meanwhile, Apple could replace the squarish camera island in favour of a large rectangular camera bump that will house the triple-camera setup (more on this later). The iPhone 17 Pro lineup could also have a new orange colour option — one of the more vibrant shades offered by Apple — a sharp departure from the muted colour options we have seen in the past. Apart from that, there could be four other available colours: black, white, grey, and dark blue. Apple could continue to offer the iPhone 17 Pro and iPhone 17 Pro Max in 6.3-inch and 6.8-inch sizes. The Cupertino-based tech giant might also finally offer an anti-reflective display coating similar to Samsung's Galaxy devices — though this leak should be taken with a pinch of salt for now. The Pro models could also see some changes to the Dynamic Island, which might be made slightly smaller. However, they could lose their exclusivity over the ProMotion technology, with leaks suggesting that Apple may expand it to all four iPhone models this year. The iPhone 17 Pro and 17 Pro Max could run on the new A19 Pro silicon from Apple, based on TSMC's new 3nm process technology. There could also be a big boost in RAM, with leaks suggesting the Pro variants may offer 12GB of RAM — up from the 8GB seen in all four iPhone 16 models last year. The upgrade would help improve the performance of Apple Intelligence features along with other multitasking tasks. Apple could also introduce a vapour chamber cooling system to help with heat dissipation and prevent thermal throttling in the iPhone 17 Pro series. The biggest upgrade for the iPhone 17 Pro Max could be in the battery department, with the phone rumoured to come with a 5,000mAh battery compared to the 4,676mAh unit seen in the iPhone 16 Pro Max. Meanwhile, both Pro models could, for the first time, get the ability to reverse wireless charge at 7.5W. They are also expected to support 45W wired fast charging and 25W wireless charging, even with third-party chargers. All the new iPhone 17 series models are expected to come with an improved 24MP front-facing camera, up from the 12MP shooter on the last generation. The sensor is expected to improve image quality while also allowing images to be cropped without quality loss. Meanwhile, the telephoto lens is also expected to be upgraded to 48MP from the 12MP shooter on the iPhone 16 models. With this change, the iPhone 17 Pro models would have three 48MP cameras — the wide and ultra-wide lenses are already at that resolution. The Pro models could also support recording up to 8K video. Apple might also add dual-video recording, a feature common in many Android phones, allowing users to record from both the front and rear cameras simultaneously.
