    Stochastics: Yield-Killing Gap No One Wants to Talk About

    There are large teams of defect inspection engineers who work on this. The published "stochastic" defects are usually CD-dependent (there's a window), low-probability. But the closest an equipment can do would be particles. Those can have a variety of signatures. For small particles in wet...

    Stochastics: Yield-Killing Gap No One Wants to Talk About

    Glad to see others sending the same message on a topic I've broached many times before. Chris has been in lithography since earlier than when I started. Another researcher in this field publishing relevant results with much more plentiful computational resources is Hiroshi Fukuda of Hitachi.

    Stochastics: Yield-Killing Gap No One Wants to Talk About

    By Chris Mack, CTO, Fractilia 07.18.2025 The Stochastics resolution gap costs chipmakers billions in delayed yield ramps, compromised performance, and unrealized revenue at 2nm and below. In semiconductor manufacturing, the laws of physics don’t negotiate. They don’t care about roadmaps or...

    Samsung to Produce Tesla Chips in $16.5 Billion Multiyear Deal

    Practically Tesla's fab now. Maybe they can handle the tool installations from the very beginning!

    Samsung to Produce Tesla Chips in $16.5 Billion Multiyear Deal

    Just a few weeks ago, they were delaying the launch of the Texas fab even: https://www.trendforce.com/news/2025/07/04/news-samsung-reportedly-delays-texas-fab-launch-amid-client-shortage/ The construction deadline has been pushed to the end of October 2025. The process is still TBD it seems.

    Samsung to Produce Tesla Chips in $16.5 Billion Multiyear Deal

    The Texas fab just finished construction? https://www.digitimes.com/news/a20250423VL206/samsung-tsmc-fab-texas-demand.html Apparently not even.

    US startup xLight raises $40 million in race against China for key chipmaking laser

    That's plausible, there are definitely precedents for that. But that would defeat the motivation to keep technology development control in US.

    US startup xLight raises $40 million in race against China for key chipmaking laser

    The basic problem is ASML wants control over the light source. That's the reasoning behind the Cymer acquisition. The previous American lithography machine maker SVG was also acquired by ASML.

    Samsung delays HBM4 rollout to 2026 due to 1c yield challenges

    Samsung Electronics is reportedly pushing back the mass production of its next-gen high-bandwidth memory (HBM) chips to 2026, signaling a more cautious rollout amid ongoing DRAM redesign efforts. The company originally planned to start mass production of its 12-high HBM4 modules, which are...

    Intel 10Q filing - We may cancel 14A if we do not win a large external customer

    Well, CFO had also mentioned that with the 18A test chips they had lost some customers: https://www.reuters.com/business/intel-has-limited-customer-commitments-latest-chip-manufacturing-tech-cfo-says-2025-05-13/.

    Intel 10Q filing - We may cancel 14A if we do not win a large external customer

    As long as they're not confidently executing SAQP, I doubt they can advance quickly. SAQP is about how well they can leverage existing modules.

    New four element semi material, A real advance?

    This looks harder than pure Si epitaxy (for nanosheet transistors), since you have to arrange the precise composition of four elements.

    US startup xLight raises $40 million in race against China for key chipmaking laser

    I wonder what's the business model. Besides ASML, who is skeptical and more motivated to continue their own LPP technology, can't imagine another customer.

    $55 Billion Michigan Chip Plant Cancelled Amid Tariff Uncertainty and Economic Turmoil

    Well that's a pity. It also seems they ruled out any domestic location with the "massive national economic uncertainty." I guess there's also the complication of the fab JV with Kioxia.

    Taiwan’s Semiconductor Paradox: Why TSMC Soared, DRAM Sank

    The key thing was there were plenty of domestic design clients that TSMC could serve. Also, at the time, making commodity DRAM was more capital-intensive. Key technology IP was also licensed.

    ASML Lowers 2025 H2 Revenue Forecasts as Q2 Results Surpass Analyst Expectations

    The world’s largest computer chip manufacturing equipment vendor, ASML, has said that it might fall short of its 2026 growth targets, CNBC reported. The company made this announcement on July 16, even as ASML Q2 2025 results surpassed analyst expectations. ASML’s Q2 net sales stood at 7.7...

    Rapidus Achieves Significant Milestone at its State-of-the-Art Foundry with Prototyping of Leading-Edge 2nm GAA Transistors

    "prototyping of 2nm GAA transistors and attaining electrical characteristics" sounds like very basic, low sample size, like they're just starting. "Fully single-wafer processing" sounds like low volume, which might be expected in the starting stage.
