Why Jio, not Huawei, poses the greatest threat to Nokia & Ericsson

Indian telecommunications giant Jio intends to start using its own 5G equipment within its domestic network before the end of 2020,

Check the name of the author, then it is crystal clear why the hallucination. Seriously, Samsung may have a much much much better chance in threatening Nokia and Ericsson.
Check the fact, Huawei started in the early 3G era, it catched up to Nokia and Ericsson in the late 4G era, now it is leading 5G. It took Huawei more than a decade to do the catching job. Wait 10 years, then we can revisit this subject.

Didn't Huawei, a few yrs ago, send its source codes to India to b examined by their security office?
Also, huawei's worldwide network monitoring center is located in India, it was built like 10 yrs ago, no?
And that means India knows how to make working 5G out of its own hands? Work in the industry for 10 years, then you know what it takes to catch up and beat others. Winning competition is by decades of hard work, not by lips.

Interesting report that the U.S. maintains the HIGHEST levels of R&D in semiconductors across any country:

Please, Log in or Register to view URLs content!

R&D Expenditures as a Percentage of Sales (p. 11)

US 16.4%
Europe 15.3%
Taiwan 10.3%
Japan 8.4%
China 8.3%
Korea 7.7%
Others 5.3%

Since 1999, US R&D expenditures have grown at 6.6% a year in semiconductors. Asian low value manufacturers don't do much R&D.

In 2019, the U.S. government continued to fund semiconductor research programs at the Departments of Energy (DOE) and Defense (DOD), the National Institute of Standard and Technology (NIST), and the National Science Foundation (NSF). The Administration has also recently announced new research programs aimed at supporting the U.S. semiconductor industry, including DOE’s quantum information science initiative and DOD’s Electronics Resurgence Initiative (ERI) and Microelectronics Innovation for National Security & Economic Competitiveness (MINSEC) programs.
That's not surprising. Most of the upstream equipment in semiconductor industry are either US or European.

I could be wrong here but I think the math on this should be pretty straightforward. If we simplify each nanogap to a single transistor spacing that would be 500,000 transistors per hour. Apple’s recently announced A14 chip has almost 12 billion transistors. Just for a single A14 chip alone that would take 24000 hours. If the transistors are stacked you can divide that by a factor of 3. ASML’s current EUV scanners can output about 120 *wafers* per hour, and each wafer is multiple chips. This is why production at scaled requires masked scanners, and why masked write tech is difficult to scale.


To be clear scanners don’t make full transistors either. They make the specific material and chemical trace patterns for the transistor spaces. The transistors themselves are then created with implantation and deposition machines.

I find it hard to imagine the scientists are that deluded as to make chips literally by printing transistors by transistors.

I suspect the "nanogap process" has to do with the packaging of the die (one of the hundreds in a wafer) where electrical connections are made between the circuits in the die and conductors that will finally lead to electrical connections on the IC packaging.

So how dependent is China? And if so, can US decapitate Huawei?

America Is Going to Decapitate Huawei

rest of the article:
That guy who wrote that article is a bozo.

That article writer actually writes:-
"But dig deeper and China’s position looks weaker."

Yeah, but, look at this thread, people here digging deeper than he would even dare. Dig deeper like this thread, he will not like what he sees.

Bottom line, inside China SMIC is already at 14nm.

Huawei 5G base stations probably do not absolutely need 7nm chips, but they got a stock pile of that.

One point should be emphasized at this juncture, and that is China and America has passed the point of no return in their tech war.

Insert obscenity here! Dui.

:D

Well there’s a reason no one uses direct write for anything but extremely custom chips. Direct write is usually used to make masks for scanners or to do defect repair instead. It’s a lot more precise but a lot less scalable.

Use of these in semiconductor manufacturing seems to be connectors for molecular components or act as source-drain electrodes, from what I've gathered.

Foundry Capacity
By technology, Samsung's foundry business derives around 20% of sales from 5-7 nm chips, 20% from 10 nm chips, 21-23% from 14 nm chips, and around 40% from legacy processes. By comparison, TSMC derived 36% of sales from 7nm and below in 2Q 2020.

TSMC has a total capacity of 1 million 300mm wafers per month compared to less than 400,000 for Samsung, as shown in Chart 1.

China’s Huawei Opens Tech Centre, Consolidating Presence in Serbia

Huawei opened an Innovations and Development Centre in Belgrade just a week after Serbia signed an agreement in Washington which appeared to commit it to excluding the Chinese tech giant from cooperating in its 5G network.

Huawei’s Innovations and Development Centre was opened on Monday in the presence of Serbian Prime Minister Ana Brnabic and the Chinese ambassador to Belgrade, just a week after Serbia signed a controversial agreement in Washington which appeared to target Chinese involvement in the development of 5G in Serbia.

Brnabic said the centre will significantly help further digitalisation in Serbia and that despite the Washington agreement, the country was working on many other technologies with Huawei that are a precondition for the introduction of 5G.

“Many things are being prepared with Huawei, which will only be visible in the next few months or a year,” Brnabic said.

She insisted that cooperation with Huawei on the introduction of 5G network in Serbia is does not contravene the agreement signed in Washington.
