Yin Zhiyao, Chairman of AMEC, was awarded the Forbes China Lifetime Achievement Award and Best CEO.​

Yin Zhiyao said in his acceptance speech, "I am truly flattered to receive this honor. In 2004, I led a team of 15 people back to China from Silicon Valley to found AMEC. Today, the company has grown to a scale of about 3,000 employees, annual sales of over 12 billion yuan, and a market value of over 200 billion yuan. This is by no means solely due to my personal efforts. I am grateful for the opportunities brought by the country's reform and opening up and industrial development, for the strong support and assistance from leaders at all levels of government, shareholders, and all sectors of society, for the joint efforts of the AMEC management team and all employees, and I am also deeply grateful for the companionship and encouragement of my family."

Yin Zhiyao humbly pointed out that although AMEC has reached the international advanced level in the field of semiconductor microfabrication equipment, its overall scale is still medium and it is still in a period of rapid growth. He said, "Looking to the future, I cannot stop. I must work hard for another 20 or even 40 years, and work together with the tens of thousands of employees at AMEC to develop AMEC into a world-class microfabrication equipment company!"

成都华微 (CEC/CSMT) having discussion with Unitrend and 吉赫科技/Gigahertz tech a Chengdu company to put 华微's high speed ADCs in high-end oscilloscopes, signal sources, and other test/metrology instruments

oscilloscopes using CSMT's ADC can achieve capture capabilities of 64B data pt per second.

So yes, looks like domestic high-end ADCs is going to really speed up development of various oscilloscopes, signal generators and such.

Intel, AMD notify customers in China of lengthy waits for CPUs​

Intel and AMD have notified Chinese customers of supply shortages for server central processing units (CPUs), with Intel warning of delivery lead times of up to six months, people with knowledge of the delays said.
The supply constraints have driven up prices for Intel's server products in China by more than 10% generally, although pricing varies by customer contract, according to one of the people.

In China, which accounts for more than 20% of Intel's overall revenue, its fourth- and fifth-generation Xeon CPUs are in particularly short supply, with Intel rationing deliveries, two of the people said.
Intel has a substantial backlog of unfulfilled orders for these models, with delivery times extending as long as six months, they added.
AMD has also informed clients of supply constraints, said one of the people and a third source. Delivery lead times for some AMD products have been pushed out to eight to 10 weeks, the third source said.

Intel has struggled to ramp up production amid persistent manufacturing yield challenges. AMD outsources production to Taiwan's TSMC, the world's top contract foundry, which has prioritized AI chip manufacturing and left limited capacity for CPUs.

Damn...

Didn't expect the memory supply crunch to also effect CPU's at this point what isn't effected by rapid AI infrastructure build out.

China still has Hygon for X86 CPU supply tho, seems like a good moment for domestic CPU makers.

this could be one of trump's sanctions.

I can assure this is a huge issue for the hyperscalers in America. You need CPUs for all the racks that they are building out. People have been so focused on GPUs and memory chips that CPU capacity didn't get ramped up the same way and this is possibly causing delays now.

Great time for Huawei

Guangzhou Micro-Nano Lithography Materials product matrix now include photoresist with 40nm-28nm resolution and increased shell life. EUV roadmap till 2030.​

The company's current main R&D focus is on high-end ArF photoresists with nodes ranging from 90 nm to 28 nm. These photoresists have achieved leading domestic performance and are approaching the mainstream global level represented by Japanese photoresists. The aspect ratio of the 55 nm node can reach 3.2:1; the 90 nm node photoresist exhibits excellent linewidth profile and superior uniformity. Among other key indicators, the DOF (Distribution of Free) with an 82 nm linewidth can reach 300 nm, ensuring exposure stability and achieving a shelf life of up to 10 months.​

A Tsinghua University team has developed a novel grating interferometer that enables multidimensional measurements with atomic-level precision.​

A research team at Tsinghua University, led by Associate Professor Li Xinghui, has developed a novel zero-dead-zone heterodyne grating interferometer capable of multidimensional, atomic-level precision measurements. Addressing the "dead zone" challenge common in current laser interferometry, the team utilized symmetric arrangements of dual two-dimensional gratings and dual-frequency lasers. This innovation physically aligns the reference and measurement optical paths, eliminating path length differences. Consequently, the compact 90×90×40 mm³ system achieves high performance, including a resolution of 0.25nm on X and Y axes, 0.3nm on Z, and linearity up to 6.9×10⁻⁵.


The team also solved the critical issue of crosstalk error, which can plague high-precision multidimensional measurements. By classifying these errors into system, mounting pose, and inherent motion system types, researchers employed continuous wavelet transforms and digital signal processing to accurately identify and separate noise from real data. This methodology successfully reduced the overall crosstalk error to below 5%, significantly enhancing the authenticity and accuracy of the three-degree-of-freedom (X, Y, Z) displacement measurements.

The researchers highlighted the profound industrial significance of this technology, particularly in extreme ultraviolet (EUV) lithography and advanced chip manufacturing. The ability to measure nanometer-level alignment across multiple axes is crucial for maintaining Moore’s Law and enabling new materials and medical robotics. Currently progressing towards industrialization, this breakthrough marks a vital transition from basic precision to atomic-level mastery, providing the foundational technology required for breakthroughs in ultra-precision manufacturing and metrology.

Looking ahead, the research team plans to expand the system’s capabilities from three to six degrees of freedom, aiming for picometer-level static resolution and nanometer-level dynamic performance. Future goals include developing intelligent systems capable of self-diagnosis and self-calibration to ensure plug-and-play, maintenance-free operation, thereby lowering requirements for the operating environment and operators.
