I have heard about this but i am still unsure what exactly this N1 and N2 is. Is this a proper 7nm/8nm Chip or just an improved 14nm Chip. What are your thoughts Skywatcher?

If this N1 and N2 is a proper 7nm/8nm Chip made with the 7nm/8nm process, then it is very likely the 7nm Localised Production Line will be ready late 2020.

If N1 and N2 is just a improved 14nm Chip with performance close to a 7nm/8nm Chip, then the 14nm Localised Production Line will be ready next year.

We will just have to wait till next year to find out.

In any case, for general semiconductor machinery, i think equipment for 7nm is probably just a improvement over the ones that are used for 14nm. It shouldnt take too long for 7nm equipment to come out. Unless of course a completely new type of machine or process is needed.

Here's some info:

Now, with funding from the government, SMIC is developing 12nm finFETs and what it calls “N+1.” 12nm is a scaled down version of 14nm. Slated by year’s end, N+1 is billed as a 7nm technology.

N+1 isn’t quite what it seems. “SMIC’s N+1 is

to Samsung’s 8nm, which is slightly better than TSMC’s 10nm,” said Samuel Wang, an analyst at Gartner. “SMIC’s N+1 is unlikely for this year. 12nm may become production ready by the end of 2020.”

China’s state-backed SMIC (Semiconductor Manufacturing International Corporation) has set an ambitious target of Q4-2020 for its 7 nanometer-class N+1 foundry node to go live, achieving “small scale production,” according to a cnTechPost report. The company has a lot of weight on its shoulders as geopolitical hostility between the U.S. and China threatens to derail the country’s plans to dominate 5G technology markets around the world. The SMIC N+1 node is designed to improve performance by 20%, reduce chip power consumption by 57%, reduce logic area by 63%, and reduce SoC area by 55%, in comparison to the SMIC’s 14 nm FinFET node, Chinese press reports citing a statement from SMIC’s co-CEO Dr. Liang Mengsong.

Granted, N+1 could start small scale production in 2020 Q4 and not really be available for 2020 in any meaningful marketwide sense.

China will block this ARM sale for sure, unless they branch out ARM's patents and sell to China. From then on China can move on with its own development of ARM patents.

Does China have any says of this ? How does it work ? Can Trump just make another (many many) an executive order?

Yeah I don't know how it works either but I remember when US senators were toying with allowing US companies to violate Chinese intellectual property in order for the US to produce domestic 5G. Yeah they can do that but then what's to stop China from violating all the US IP it wants? Just like Trump threatens to decouple and have the US have no relations with China. China can still produce many US products and sell them to the world and this time keep the profits for themselves. It's the same exact product but cheaper.

YMTC’s 64L 3D NAND device is a disruptor not only because it is offered by a significant new entrant, but because of its Xtacking architecture. YMTC is already on track for 128-layer QLC (quad-level cell) 3D NAND offerings that max out at 1.6 Gbps. This was revealed back in April. Given YMTC’s recent collaboration with ‘Phison’, we can assume that the drives are using a Phison controller, though it can be a custom controller from ‘Silicon Motion’ as well.

. Previously, the PLAN had to rely on early warning helicopters to be the “eyes in the sky,” but these rotary aircraft could only carry smaller radars and had a limited speed. As such the helicopters could cover a radius of some 200 kilometers, while the fixed-wing AEW could cover 400 to 500 km much quicker.

.Is SB being forced to sell it to a US co so that Arm tech is blocked in China?


SoftBank Group Corp. is nearing a deal to sell British chip designer Arm Holdings to Nvidia Corp. for more than $40 billion, according to people familiar with the matter, the latest in a series of big asset sales by the Japanese technology conglomerate.

The cash-and-stock deal being discussed would value Arm in the low $40 billions, the people said. The terms under discussion would mark a big win for SoftBank, which bought Arm four years ago for $32 billion and had struggled to jump-start growth in the business.

Huawei Petal Search goes head-to-head with Google

Petal Search started out as a

like the Play Store. But it’s quickly turning into a much bigger project. Scouring the web for official APKs has taught Huawei a lot about web crawling and indexing, so much so that it’s expanding Petal Search to act much more like a general search engine. Banning Huawei from using Google seems to have only spurred the company to fill in the gaps itself.

Does Phison use any US technologies, even it is a Taiwanese company? If it is the case, it could be blocked by this administration
