must point out that FMM is not a material, but a component. It stands for fine metal mask and serves as a mask for patterned deposition of OLED materials. It is not a photomask (no photolithography involved) but a direct shadow mask due to the pixel size being relatively large. The deposition patter replicates the mask pattern.

How difficult is it to make this part? It so happens that no Chinese company was making this part before?

it can be made by photochemical machining/i-line photolithography. The full i-line photo supply chain is inside China. it is usually more cost effective to get this sort of work done at a dedicated mask shop. much of the time, the reason Chinese companies don't do something is because it isn't cost effective, not because they physically can't do it. when they're given a reason to do it, they do it.

Nation persists in driving R&D leading world with 4.21 m valid invention patents

China has been persistently promoting scientific and technological innovation, which is evidenced by the rising number of valid invention patents and increasing research and development spending.

By the end of 2022, the effective amount of invention patents in China reached 4.21 million, of which 3.28 million were held by inventors from the Chinese mainland, the country's top intellectual property regulator said during a recent press conference.

"China is the first country in the world that embraced more than three million of valid invention patents, of which the ownership of high-value invention patents reached 1.32 million, an increase of 24.2 percent year-on-year, accounting for more than 40 percent of the total volume of invention patents," Hu Wenhui, deputy head of the National Intellectual Property Administration, said on January 16.

The latest report of World Intellectual Property Indicators released by the World Intellectual Property Organization also showed that China has ranked top in the world in terms of the number of valid invention patents, Hu added.

According to the official, China saw more enterprises applying for patents over the past year, demonstrating the growing innovative dynamism across the economy. By the end of 2022, 355,000 Chinese companies had valid invention patents, an increase of 57,000 over the previous year.

The driving force in the growth of China's valid invention patents lies in various fields of digital technology, such as information technology management and computer technology. In 2022, the number of patents granted for inventions in the core industries of China's digital economy was 325,000, an increase of 17.9 percent year-on-year.

In addition, China also saw rapid growth in patents and trademarks granted to foreigners in 2022. The number of valid foreign invention patents in China reached 861,000 by the end of 2022, up 4.5 percent from the previous year, while the number of valid trademarks registered by foreign parties in China reached 2.03 million, up 5.9 percent year-on-year.

The performance of invention patents is directly linked to the country's continuous increase in research and development (R&D) funding.

Data from the National Bureau of Statistics recently showed that in 2022, China's total expenditure on research and development continued to maintain double-digit growth for seven consecutive years, with the total amount exceeding 3 trillion yuan ($444.7 billion) for the first time, up 10.4 percent from 2021.

Research and development funds the intensity of funding investment (the ratio of R&D funding to GDP) increased at a faster pace, reaching 2.55 percent, an increase of 0.12 percentage points, a new record.

I believe that at this time, this particular statement by President Xi can be seen as an open, official declaration by the Chinese leadership and government that the tech race and tech war between China and the US is now in full steam.


Go China! Do the Chinese people and the global community (especially the developing world) proud and strong!

China's fourth-generation light source facility installs new unit


China's latest high-energy synchrotron radiation light source facility, the High Energy Photon Source (HEPS), on Wednesday installed its first pre-aligned unit inside the storage ring tunnel, kicking off the comprehensive construction of the HEPS accelerator.

A crucial part of the light source for accelerating electrons and generating synchrotron radiation, the storage ring is designed to achieve ultra-low emittance when charging particle beams and thus requires high precision for the construction.

Scientists and engineers at the Institute of High Energy Physics (IHEP) under the Chinese Academy of Sciences (CAS) have adopted an improved hybrid design of magnet systems and made them standard cells that can be pre-assembled in labs at higher precision.

At a circumference of 1,360.4 meters, the storage ring would need 288 of such pre-collimated units, according to Qu Huamin, the chief engineer of the project.

The HEPS accelerator consists of three separate accelerators – the storage ring, the booster and the linear accelerator or linac – which together provide high-quality synchronized light for the beamlines.

Located in Huairou District to the north of suburban Beijing, the facility takes up an area of more than 20 soccer fields. It is China's first fourth-generation synchrotron source and one of only a handful of such facilities in the world.

Started in 2019 and expected to be completed by the end of 2025, the HEPS can provide 60 to 70 beamlines at high brightness with more than 90 experimental stations.
