Ezhou Xinruiyang Semiconductor Laser Manufacturing Project with an investment of 500 million yuan started​

According to Ezhou Media, on August 16, the Ezhou Xinruiyang semiconductor laser production and manufacturing project with an investment of 500 million yuan officially started.

The project focuses on the research and development and design of optical components, breaking through key technical bottlenecks, and achieving domestic leading product precision. After completion, it will have an annual production capacity of more than 10,220 sets of semiconductor lasers, with an estimated annual operating income of more than 400 million yuan and an annual total profit and tax of 60 million yuan. It will create more than 350 jobs, form a clustering effect with more than ten optoelectronics industry enterprises in Ezhou, and fill the gap in the upstream core component industry chain of Ezhou's optoelectronics.

A semiconductor laser, also known as a laser diode, uses semiconductor materials as its working medium. It is one of the most widely used and produced types of lasers. It generates laser light through the recombination of electron-hole pairs within the semiconductor material, releasing energy and achieving stimulated radiation. It boasts significant advantages such as small size, high efficiency, long life, and low power consumption, playing a core role in numerous fields including industry, communications, healthcare, and consumer electronics. According to data, Ezhou Xinruiyang Technology Co., Ltd. was established on July 27, 2023. The company's independently developed semiconductor lasers boast internationally leading performance and domestically leading product precision.

Nice.

I'm always on the cautious side and I'm concerned that the numbers are real, but not for Mate 80. The same Weibo people also said N+3 went into trial production in Q4 last year. It took TSMC N5 1.5 years to ramp up yield so there really isn't much time for Mate 80.
i mean it takes months to complete 1 batch. If they actually entered trial production in Q4 of last year, then the process must have been already stable enough to be tried on scale.

Basically, we have N+1 at 46nm pitch iirc
N+2 at 42nm and then 40nm
N+3 at 36nm seems like the next logical step to be

And going through a few batch for improving yield. Given the rash of rumors I have seen in the past month about Mate 80 and SoC and no hint of delays, I could only assume the yield is good enough for this process and that they've produced enough to be loaded into initial Mate 80 phones by this point.

Old enough to remember when 5G was the tech that would have change the world, from surgery in your home to flying cars. The military will have smartphone connected drones and jet fighters. A drone operator would be bombing wedding parties in Kabul with his smartphone from home. That if the US lose the race will be a third rate power. US D.C. think tank stooges have the habit of overhyping technologies that they don't understand for political gains.
What people haven't realized is 5G was absolutely world changing and they were right, who ever wins, wins it all. China won and we are seeing the results. They're down playing it now saying they don't even need 6G because 5G changed so little. But that's because they aren't China.

5G completely changed logistics in China. How do you think China is coordinating all those super ports? We can have those giant car carriers because of 5G. Localized communication on ships like that would be wildly inefficient.

5G allows the existence of dark factories. Again, complete coordination and communication between different parts of the factories let's the robots do all the work without humans.

5G allows China to efficiently mine all those rare earths with robots significantly improving yield and safety.

5G allowed China to create what the West calls the over capacity problem. It's not subsidies, it's 5G and the efficiency gains from that. So to think that winning the 5G war was anything less than a world changing victory misunderstands what happened.

I agree that you would be correct, but in all those automation there are more than just 5G, a lot is complemented using China space satellite network, it required a lot of computational power just to automate at that level, so here comes the contribution of semiconductors and photonics for fast networking. And then you have Beidou contribution to China and the rest of world for access to precision positioning.

The US has a big 5G penetration but I don't see the dark factories and the efficient autonomous ports, except better netflix experience and no even that, because that trash of a company just randomly downgrade the streaming to save bandwidth. So I correct myself, 5G alone is not the game changer, that justify killing another major power companies creating a geopolitical tech minefield. Like always is a combination of technologies that is the game changer.

China EV alone was not the game changer, It was China EV technology + Battery advancements + Silicon Carbide - Power Electronics Advancements.

Huawei & Shandong University Breakthrough: 1200V Fully Vertical GaN-on-Si MOSFET​


Huawei and Shandong University recently jointly reported on a 1200V fully vertical GaN-on-Si trench MOSFET (FIT-MOS) utilizing a fluorine-implanted termination (FIT) structure. The inherent negative charge in the FIT region of the FIT becomes a resistive region, a natural isolation device that replaces the traditional mesa-etched termination (MET) and eliminates the electric field concentration effect at the mesa edge, thereby increasing the BV of the FIT-MOS from 567V to 1277V. Furthermore, the fabricated FIT-MOS exhibited a Vth of 3.3V, an ON/OFF ratio of 1e7, and an Ron,sp of 5.6mΩ·cm². These results demonstrate the great potential of cost-effective GaN-on-Si vertical transistors in kV-class applications. The related work was published in IEEE Electron Device Letters under the title " 1200 V Fully-Vertical GaN-on-Si Power MOSFET ."
