HD SRAM bitcell size shrink beyond 7nm node by CFET without EUV​

Abstract:
As the critical dimensions of the transistor continue to be shrunk, the industry enters the EUV lithography era after the 7nm node. Due to the current high economic costs of EUV lithography in terms of equipment and process, it is desirable to achieve device area shrinking without using EUV lithography. In this paper, we introduce HD SRAM EUV-free designs using CFET. Various layout designs are put forward according to the feature of CFET, and their feasibility is evaluated. All the designs basically obey 7nm design rules and achieve impressive scaling of the bitcell area. This work provides a new starting node for CFET to increase transistor density.

If life gives you lemons learn to do lemonade.
CFET, it's like 2.5 and 3D stacking, China and Huawei are focusing on 2.5 and 3D packing, and heterogeneous stacking... it will have little for low-end chip production possible equally itchy with high-end chips.

That is from an European Austrian company called EVgroup. Similar Chinese lithography players are:

All is fair in competition, Both countries are vulnerable as they rely on others BUT as you said what is the best strategy to use. China had the confidence to compete as they rely on the whole nation approach and leverage its huge market while the US instead of trusting its friends and the trade system they created want to destroy, rewrite and control it. The effect is the opposite of what the American desire.
The West has no viable alternative strategies other than conforming to a multipolar world. The current "Rules Based Order" is basically the end product of the previous colonial imperialist system that placed Anglo-Americans at the top followed by the West & Central Europeans below them. This system worked to their favor as long as they could maintain the commanding heights of the world economy, technology and military. They do this through patent laws, international financial parasitism, and pervasive Harvard MBA style comparative advantage trade agreements that straight-jacket new comers. The problem now is that China is the first country ever to be able to overcome all these obstacles. China is close to becoming a true full spectrum peer competitor in the near horizon. Even the Soviet Union was never a full spectrum peer competitor. China can and will take over the commanding heights if the status quo continues much longer. It is probably going to pass America in gross scientific output sometime between 2023-2025 and eventually probably surpass the entire OECD combined.

Semiconductors are the gateway technology to the other lynchpin technologies of the commanding heights. Literally everything in the modern world you can think of. If the American sanctions successfully hold China back in this field, it would actually contain China for a long time. However, a long time isn't forever! Sooner or later, it would break through. The idiocy of this policy is that what should have been a long time is turning out to be a lot sooner than expected. This is like kicking yourself in the head and blaming the pain on the guy you were actually trying to kick.


Domestic 14nm line is done and dusted by 2024 a 7nm domestic line will be humming. And IF you want evidence , please wait for the Return of the King in 2023. ;)
Chinese officials have publicly announced the 14nm process being ready for commercialization but I haven't seen the same for 7nm. Even if 7nm is commercially viable by 2024, I think it would make more sense to be packaging 14nm 2.5/3D. Supposedly, they are working on improving yields but there are issues related to the photoresists, or possibly to the light sources. Nobody really knows because it's all rumors on the Chinese Internet.

Of all the bans, from the Americans trying to subvert Chinese progress in supercomputers, telecommunications, space exploration, and semiconductors, this has to be the worst and dumbest one of all.

All it is, it is software. Just lines and lines of code.

They actually know what that code is suppose to do. Monkey see, monkey do, you know. If Synopsys software has this feature, just code it in.

Problem solved. Where are they gonna find those coders? It's China. Everyone takes math. Lots of geeky computer programmers too. They don't write spaghetti code!
I disagree on this point about EDA. This is MUCH MUCH harder than it may seem from a technical point of view because EDA is typically developed in parallel with hardware. It can't be developed in isolation of the feedback loop needed to perfect it. The flipside is that it will effectively self-blockade American semicon equipment as you mention.


Give it a few months at the most, and they would have pirated or replaced this EDA.
Pirated EDA might work for foreign semicon equipment for now, but who knows what kind of tripwires have been embedded in foreign semicon equipment and foreign EDA to f**k over China. China will eventually need to support its own EDA softwares on it's own semicon equipment. This takes time and time is what the Americans are expecting to gain from this so that they can reshore, recapture and indeed control not just the semicon industry but all downstream high technology industries.

how do you think semiconductor equipment talks to EDA files? I don't know. My understanding is that the EAD file output is used for a mask set. The equipment does not talks directly to the EDA files.

from my experience, something like an CVD instrument or dry etcher has just a few parameters: temperature, pressure, gas flow, gas type (valve selection), time. The core IP is in the physical parts of the instrument - like controlling the wafer platen for high uniformity with different heater channels, corrosion resistant internal coatings, etc. The controls are comparatively not so complex. You can manually control this or have it be on simple recipe control. Here's an example.
