Gpixel launches the first CMOS image sensor for disposable medical endoscopes​

On January 9, 2025, Gpixel released its latest CMOS image sensor and optical module for disposable endoscopes - GXS1508/GXSM1508. The launch of this product opened a new chapter for Gpixel in the field of medical imaging, and also provided more product options for the field of medical endoscopes.

In order to meet the needs of different types of customers, Gpixel provides two types of products: CSP packaged chips and wafer-level optical lens modules.

Size less than 1 mm, CSP package, GXS1508 CMOS chip

The GXS1508 has an effective pixel resolution of 400 x 400, a 1.5 um back-illuminated rolling shutter pixel design, and an optical size of only 1/19 inch. In addition, the chip uses analog signal output, with a frame rate of 30 fps at full resolution, which can perfectly adapt to mainstream ISPs (image signal processors) to facilitate analog-to-digital conversion and subsequent image processing. The GXS1508 consumes less than 20 mW when operating at full resolution and full speed, which can significantly reduce the temperature of the endoscope module and provide better image quality for medical endoscopes. The GXS1508 adopts a compact 4-pin CSP (chip-scale package) package format with a size of only 0.961 mm x 0.961 mm x 0.55 mm, which is fully suitable for the use of small-pipe endoscopes.

Thanks to Gpixel's years of technological accumulation in the scientific and industrial fields, GXS1508 also has excellent characteristics such as low noise and high dynamic range, and can produce clear images even in low-light scenes.

Zhuhai: Focus on the development of new generation compound semiconductor substrate materials and epitaxial wafers such as 8-inch and 12-inch silicon wafers​

According to the official website of Zhuhai Municipal Bureau of Industry and Information Technology, on January 7, Zhuhai Municipal Bureau of Industry and Information Technology publicly solicited opinions on the "Three-Year Action Plan for the Development of Zhuhai's Electronic Chemicals Industry (2025-2027) (Draft for Comments)".
It mentioned that the focus is on the development of 8-inch and 12-inch silicon wafers, new generation compound semiconductor substrate materials and epitaxial wafers such as silicon carbide, gallium nitride, and indium phosphide; and the forward-looking layout of fourth-generation semiconductor materials such as gallium oxide, gallium antimonide, and indium antimonide. At the same time, the focus is on the development of uniform chrome photomasks, KrF and ArF shift photomasks, and the forward-looking layout of deep ultraviolet (DUV) masks.
We must also keep a close eye on the technological progress trends in the "More Than Moore's Era", focus on the supporting needs of advanced packaging processes such as 2.5D/3D integration and packaging, chiplet technology, and heterogeneous integrated advanced packaging, and focus on the development of organic packaging materials such as transparent alicyclic epoxy resins; inorganic high-performance ceramic packaging materials such as alumina; and other advanced packaging materials such as wafer carriers.​

Pura 80 Ultra (some sources say it will be called Pura 80 Art) rumor roundup including some information already posted:

SoC: Kirin 9020+ (credible sources imply it will score 125K-130K AnTuTu up from 120K-125K).

Main camera: 50 MP 1" fully domestic CMOS with variable aperture. Multiple highly credible sources imply it will be designed by SmartSens and fabbed domestically.
Telephoto camera: 50 MP 1/1.3" CMOS with 3x to 5x retractable optical zoom and macro capability. The periscope zoom component is implied to be made by Ofilm by some sources, but they are not 100% credible. Source (Fixed Focus):

Ultrawide camera: 50 MP, but will be worse than Pura 70 Ultra. Source (Digital Chat Station, highly credible):

Some comments: The Pura 80 Ultra looks like it will revolutionize mobile photography a la the Huawei phones pre-sanctions. The main camera on the Mate 70 Pro+ already has the most detail out of any smartphone in daylight, and a bigger sensor will greatly improve nighttime performance and digital zoom. The telephoto will be the largest telephoto sensor out of any smartphone, which should make it the best zooming telephoto among 2025 flagships (the Pura 70 Ultra was basically the worst in this category).

If these rumors are true, it really shows how far ahead of the game Huawei is at miniaturization and how much R&D they put into it (the Mate XT is another example). Other flagships either have to compromise on hardware (iPhone/Samsung) or have a huge camera bump (Xiaomi/Oppo/Vivo). Huawei cramming the largest main camera sensor (with variable aperture, which takes up additional space), the largest telephoto sensor with almost the longest focal length (second only to Oppo, which has a much smaller sensor), and a huge battery into a chassis the size of an iPhone 16 Pro Max is insane considering that the Pura's worse SoC requires more cooling material. This requires many new technologies like retractable cameras (debuted in Pura 70 Ultra), silicon-carbon batteries (debuted in Honor Magic5 series, but the patent is owned by Huawei), and 3D mainboard design (from foldable phones)

On a personal note, I have the Pura 70 Ultra, Mate 70 RS, and will be getting the Mate XT and Pura 80 when they are released globally. Super excited!

Now that ASML is no longer allowed to service certain machines in China. Can China still continue to make 7nm chips.

And is there any clarity on China's domestic 28nm DUV machine the SMEE SSA-800.

 

[Franklin]

Yes, this is an entirely ridiculous policy.

The DC blobs have gone off on the deep end and fully decided that AI chips are like military weapons.

so this probably restricts the legal sales of Nvidia GPUs (even the low end ones) to China to a certain fixed amount. I presume Huawei is thanking them for this since it has plenty of Ascend NPUs to sell.

But other than that, I'd assume the smuggling business through Japan, Korea, Singapore & Taiwan will continue to bring in plenty of Nvidia GPUs.

It does open up Ascend sales to non-US allied countries.

This has nothing to do with the fear of the Chinese military using super fast chips. By holding back China on AI they hope to hold China back on other industries and technologies. This is pure and simple economic warfare. Same goes for the ban on Tiktok.

I am just going to say that this particular poster is not the most reliable.

that’s why I would say to take what he says with caution

ASML was not allowed to serve SMIC 7nm facilities since the end of 2022 and ASML boss stated of the undesirable possibility of Chinese companies serving these scanner themselves.

Do you think Chinese local companies doing it? I believe so, as the 7nm production still going even higher

 

[huemens]

ASML was not allowed to serve SMIC 7nm facilities since the end of 2022 and ASML boss stated of the undesirable possibility of Chinese companies serving these scanner themselves.

Are you sure? From what I remember ASML is still allowed to service those including the ones in SMIC 7nm.
IIRC, what was done in 2022 was ban US equipment and personnel from advanced fabs in China. So complete cut off from US companies. In accordance with that, ASML pulled their US personnel from China, but they continued their service using employees from other countries. That was the time Jordan Schneider did the famous "annihilation" tweet.
Then at the end of 2023 they were banned from exporting DUVi for advanced fabs, but were still allowed to service existing tools.
Towards the end of 2024 Dutch government introduced a licensing requirement to service, but as far as I know they haven't refused to give that license so far.
