TAIPEI/TOKYO -- Huawei has returned to the top of China's smartphone market after staging an aggressive comeback in the face of an ongoing U.S. crackdown, with Apple falling to fifth by shipments in Asia's largest economy.

Figures for the first quarter of 2024 released on Friday by analytics company Canalys show that Huawei shipped 11.7 million smartphones in China. This is up 70% from a year earlier, when the company, hit by U.S. sanctions, was still trying to rejuvenate its handset business.

Apple sank to No. 5 from first place, with its Chinese shipments tumbling 25% to around 10 million. Oppo's and Vivo's shipments in the home market were down 14% and 9%. Honor, which was once Huawei's budget smartphone brand but was spun off in 2020, logged 9% growth in the domestic market.

Some of things we may just have to wait to find out

For thing we are certain is Huawei currently pushing DUVi +SADP scheme hard, such as Mate 70 pro 5nm, and 3nm next year.

The equivalent scanner would be NXT 2050i. Probably this is one Huawei is targeting

Huawei stopped poaching SMEE staffs but it doesn't look like it's giving up DUVi

I believe Huawei is collaborating with SMEE and used SMEE scanner as the foundation for its improved model. After all, they both under central government directive.

My bet is Huawei lithography will be more advanced than SMEE very soon. Huawei is extremely "scary" company, well not really company, it is a cooperative entity where the employees own the company

Thats why the US is so nervous of Huawei ... nothing to do with "National Security", that term has been abused for so long by the politicians

I think Huawei will focus on developing the mythical SSA900 22nm DUVi, since SMEE is a system integrator, all the supposed components are ready for the mass production of SSA800A. Like NXT 2050i which is an improved iteration of NXT 2000i, Huawei will focus on new components development and tech coordination while SMEE on production. I see the synergies between Huawei (customer), SMIC (chip fabricator) and SMEE (equipment integrator) with cross pollination of technical feedback and ideas to push forward. Huawei is taking a bigger role due to commercial urgency and opportunity, they want to recreate the successful business venture of the Triumvirate (Apple, TSMC and ASML).

Airborne single-photon LiDAR towards a small-sized and low-power payload

Abstract​



Single-photon light detection and ranging (LiDAR) has played an important role in areas ranging from target identification and 3D imaging to remote sensing. Its high sensitivity provides the feasibility of lightweight LiDAR systems for the resource-limited airborne and spaceborne platforms. Here, we design and demonstrate an airborne single-photon LiDAR towards the compact, small-sized, and low-power payload. To reduce the system size, we utilize small telescopes with an optical aperture of 47 mm and develop the sub-pixel scanning approach to enhance the imaging resolution. With the fine scanning mirrors, we validate the super-resolution ability in the ground experiment by surpassing the system’s resolution by 2.5 times and achieve high-resolution 3D imaging in the airborne experiment. To realize low-power LiDAR, we employ photon-efficient computational algorithms and high-quality single-photon avalanche diode (SPAD) arrays. This enables us to reconstruct images from noisy data even under challenging conditions of two signal photons per pixel. Using the airborne single-photon LiDAR system, we demonstrate 3D imaging during daytime over a large area for remote sensing applications and show the capability to reveal the detailed features of various landforms and objects.

We sane people understand this. But do they? You can read articles in the MSM or read what people say in western discussion forums. Before Huawei mate 60, it was all about how China has lost the semi-conductor war, it has no hope of ever catching up without western tech, it cannot replicate the semi-conductor supply chain and so on. With Mate 60 they switched to China can never get EUV cause its magical technology that only ASML can make. They still think they can cripple China through semiconductor restrictions.

So, they will keep trying more and more restrictions. After EUV now they are restricting DUV. Next they will restrict all semiconductor machines regardless of how old tech it might be. They will try everything.
Always shifting the goal posts constantly. They downplayed it because China doesn't produce all the chip manufacturing equipment to make 7 nm chips. One doesn't hear them say those things about those "obedient" Asian countries and territories like South Korea and Taiwan. They slate one black smith who makes a good knife for not producing the hammer and anvil to make his knife, but praise two others who make good knives who also didn't make their own tools to make their knives.

Is anyone familiar with ABF, please? Care to explain a little more...

Chip Monopoly Under Threat: US, China Counterpunch Against Ajinomoto
Ikeh James April 17, 2024

Why is it difficult for China's chip industry to become self-sufficient?

Why is it difficult for China’s chip industry to become self-sufficient?
For years, the semiconductor industry bowed to Ajinomoto’s near-absolute control over a crucial material – ABF (Anisotropic Conductive Film). This dominance sparked concerns about supply chain vulnerability, particularly for the US and China locked in a tech war. But the tide is turning.

Ajinomoto’s Grip Challenged: A Shift in Policy

Both the US and China have undergone a policy shift, prioritizing domestic chip manufacturing and reducing reliance on foreign suppliers like Ajinomoto.

US Rebuilds Domestic Muscle: The US CHIPS Act directly injects investment into chip companies building factories within the US. Even smaller players like Syntronics will benefit from this act, gaining access to funding and a US-based supply chain. This strengthens domestic production and lessens dependence on overseas suppliers.

China Seeks Self-Sufficiency: The US-led restrictions on access to cutting-edge chip technology have cornered China. While ABF isn’t currently restricted, China recognizes the risk of relying on a single foreign source for such a critical material. They are actively seeking domestic alternatives for ABF to mitigate the risk of future sanctions.

Beyond Policy: The Hurdles of Disruption

Shifting the ABF monopoly landscape requires more than just government intervention. Even with a superior alternative material, convincing the industry to adopt it widely is an uphill battle.

A History of Failed Attempts: “Many companies, including Japanese and American firms, have attempted to dethrone ABF,” says Venky Sundaram, a semiconductor expert. “These efforts achieved only limited success.”

Intricate Interdependence: Chip manufacturing is a complex ecosystem where components rely heavily on each other. Changing one material can necessitate adjustments throughout the entire process, making widespread adoption a slow and challenging feat.

Industry Buy-In: A Challenge James, another industry expert, highlights the difficulty of convincing established players to switch. “The industry might be hesitant to disrupt well-established processes,” he says.

The Road Ahead: Ajinomoto’s Reign, But Change Brewing

Ajinomoto’s market dominance is likely to persist for now, as challengers grapple with technical hurdles and industry inertia. However, the implications for the US and China differ:

US: By fostering domestic production, the US aims to reduce reliance on Ajinomoto and potentially emerge as a stronger competitor in the chip market.

China: China’s focus on domestic alternatives aims to lessen its dependence on Ajinomoto and mitigate the risk of future US sanctions hindering its technological advancements.

The future of the ABF market hinges on overcoming technical challenges and gaining industry acceptance for new materials. While Ajinomoto may retain its position for now, the combined efforts of the US, China, and potentially other players could pave the way for a more comp
etitive landscape in the long run.

then they lose and get crushed. it's not that complicated.
