Intel reportedly had a big discount on 3nm wafers from TSMC until Pat decided to make some stupid comments which got Intel paying the full price of $23,000 per wafer LOL
Yes I think TSMC would take an offense if anyone would try to ruin their business.

I think "offend and demand" has become a trend in the West in their relationship with other big powers were you have stooges demanding for example demanding for you to continue to buy their stuff but a the same time putting tariff in your products. Downsizing diplomatic relationships but at the same time demanding to keep buying their bonds.

EUV Mask Blank Inspection with Multi-wavelength High Harmonic Source​


State Key Laboratory of High Field Laser Physics, Shanghai Institute of Optics and Fine Mechanics.
Center of Materials Science and Optoelectronics Engineering

Abstract:The fabrication of defect-free Extreme Ultraviolet (EUV) lithography mask blanks for future nodes remains a pressing challenge, driving the demand for high-sensitivity mask inspection tools for smaller defects. A typical EUV lithography mask blank is composed of more than 40 molybdenum/silicon (Mo/Si) bilayers coated on low thermal expansion glass, even minor imperfections in the EUV mask blank may lead to significant negative effects on the printing process. Such imperfections also called defects can be generally categorized into two types: amplitude defects and phase defects, posing extreme difficulty for non-EUV inspection systems. Therefore, in recent years, Actinic Blank Inspection (ABI) tools utilizing Microscopic Scattering Dark-field Imaging (MS-DFI) system have gained prominence; however, challenges for smaller nodes persist. These have spurred exploration of alternative sources, notably the High-Harmonic Generation (HHG) source. This work investigated the detection capabilities with HHG source using the rigorous finite-difference time-domain (FDTD) method. Normalized scattering signal intensity of different orders of HHG source are compared in order to identify the wavelength promising for enhanced detectability. The wavelength range we choose is 13.5~38 nm (i.e.,59~21th order.

Looks like U-Precision is building more precise next gen grating interferometers for EUV scanners and immersion scanners for below 14nm nodes, sub-nanometer accuracy.

work this is interesting. So, we know this was being worked on and developed early last year, but it took another 18 months for patent to be filed and announced. That means, there could be a really long period between when things are being tested and there being patents on them. This actually does make it more impressive that we've had this many EUV patents being approved.

When you can't beat them just blame the Chinese for stealing their ideas....lol

Chinese CPU manufacturer Loongson is purportedly closing the gap quickly to Western CPU manufacturers regarding raw performance.

reports that Longsoon's fourth generation is adopting a "tock-tock-tick" strategy to accelerate innovation.


Over the past several years, Loongson has taken inspiration from Intel, using its widely known tick-tock strategy to innovate on its past three generations of CPUs. The tock refers to architectural innovation, designing a new chip architecture around an existing processing node. The tick represents porting that existing architecture to a new design node. Intel generally does not utilize this design strategy anymore, with its latest Arrow Lake chips functioning on a brand-new architecture and a completely new process node.


However, Loongson has adopted the tick-tock strategy for the past three generations, bringing consistent performance improvements to its chips. That all changes with its fourth-generation chips, however. The Chinese manufacturer has purportedly decided to switch gears, utilizing a new strategy deemed tock-tock2-tick. This method adds a second architectural design optimization "pass" before the design is ported to a smaller node. Effectively, this gives Loongson's designers more time to improve their CPU designs before moving them to a new process node.

Tick-tock only made sense for Intel because they are an IDM. It is not like being a fabless CPU company using TSMC or SMIC as a foundry where the smartphone vendors like Apple or Huawei already debugged the production process for you.
Isn't Loongson also on the US entity list and restricted from accessing the most advanced nodes at TSMC?
