Chinese semiconductor thread II

[siegecrossbow]

As @tokenanalyst already explained, this is just some obscure stuff, not mainstream semi equipment or materials. Practical impact of this last stunt will be zero. Maybe Japan just feels obliged to show some courtesy to US that pushed hard in these last months to have Japan materials (especially advanced photo-resist) banned but, as of today, they just got a diplomatic middle-finger....of course anything can happen in the future...



China has succeeded already.

The virtual white flag of this tech war was raised by US in October 2023, when the new round of sanctions turned out to be a lame duck, a 200 pages of dull, bureaucratic blob. The only real thing has been forcing ASML to stop selling DUVi 28nm.

There have been no new ban extensions on US equipment (on 28nm and above), no new fronts (EDA, software, etc), no sanctions on Huawei suppliers. Mainly just raging out of frustration upon their so called "allies"....something that continues today, but the so called allies, Holland and Japan, have told US officials sent to push them: "We have suffered enough already. Let's wait until November elections, and then there will be plenty of time for new suffering in 2025".

Why TechInsights is mum about DRAM and NAND memory on the Pura 70? Why western mainstream is oddly quite mum too? They don't have the money to pay for TechInsights access? Last time it was Bloomberg that commissioned the work to TechInsights, and immediately came out with a full detailed report/article about the Mate 60, few days after phone was out.

They are mum because after they reveal that memory is Chinese (very probably, although no official confirmation yet)...they know they can only cope about it....so better to stay quiet and act like nothing happened.

China has succeeded already, the mountain pass has been crossed already, now is downhill from there...

...US is already setting up the new front line, the new trench line: exasperated protectionism, to the limit of plain import bans against Chinese chips and SME equipment, both in US and in their vassal states.

The amazing thing is that when the dust settles China may end up being the only country with a completely independent supply chain for advanced semi-conductor.

Is going to be even better than that because this companies will probably want to expand the scope of their business beyond China and they will going to find ways to establish themselves in the global supply chain, in fact is already happening, so for much of the dismay of the stooges in D.C. instead of having less China they going to have more China.​

The National Key Research And Development Plan "Robot Controller Special Chip R&D And Application" Project Was Launched.​

Recently, the launch and implementation plan demonstration meeting of the "Robot Controller Special Chip R&D and Application" project of the National Key Research and Development Plan "Intelligent Robots" was held at the Intelligent Robot Research Institute of the Industrial Research Institute of Fudan University. The project aims to use domain-specific chip architecture to solve key technical issues such as intelligent robot planning and decision-making, collaborative control, and multi-modal perception.

It is reported that this project will focus on the development of special chips for integrated sensing, computing and control controllers for robots to meet the requirements of low latency, high energy efficiency and high reliability. At the same time, the project will develop operators and operator libraries dedicated to robot control to achieve hardware acceleration of perception, calculation, and control tasks, thereby forming an overall optimization of the software and hardware system and providing universal control for intelligent robots, especially humanoid robots and other applications. Provides critical support.​

research for higher resolution dry etching​

Electron collision cross section data in plasma etching modeling​

Abstract​

Semiconductor chips are the cornerstone of the information age, which play a vital role in the rapid development of emerging technologies such as big data, machine learning, and artificial intelligence. Driven by the growing demand for computing power, the chip manufacturing industry has been committed to pursue higher level of integration and smaller device volumes. As a critical step in the chip manufacturing processes, the etching process therefore faces great challenges. Dry etching (or plasma etching) process based on the low-temperature plasma science and technology is the preferred solution for etching the high-precision circuit pattern. In the low-temperature plasma, electrons obtain energy from the external electromagnetic field and transfer the energy to other particles through collision process. After a series of complex physical and chemical reactions, a large number of active particles such as electrons, ions, atoms and molecules in excited states, and radicals are finally generated, providing the material conditions for etching the substrate. Dry etching chamber is a nonlinear system with multiple space-time dimensions, multiple reaction levels and high complexity .

Facing such a complex system, only by fully understanding the basic physical and chemical reaction of the etching process can we optimize the process parameters and improve the etching conditions, so as to achieve precision machining of the semiconductor and meet the growing demand of the chip industry for etching rate and yield. In the early days, the process conditions of dry etching were determined through the trial-and-error method, which is characterized by high cost and low yield. However, with the help of plasma simulation, nowadays people have been able to narrow the scope of experiment to a large extent, and find out efficiently the optimal process conditions in a large number of parameters. In this review, we first introduce the basic theory of the mostly used models for plasma simulation including kinetic, fluid dynamic, hybrid and global models, in which the electron collision cross sections are the key input parameters. Since the formation of the low-temperature plasma is driven by the electron-heavy particle collision processes, and the active species for plasma etching are generated in the reactions induced by electron impact, the accuracy and completeness of the cross-section data greatly affect the reliability of the simulation results. Then, the theoretical and experimental methods of obtaining the cross-section data of etching gases are summarized. Finally, the research status of the electron collision cross sections of etching atoms and molecules is summarized, and the future research prospect is discussed.​

A bit of history about the drama in D.C. about semiconductor export controls to China.

Year 2002, 9-11 happened, Taliban "defeated", lord of the ring and some guys here learning to walk.

Some guys in D.C start becoming paranoid that the gap between China and the US is closing.

sound familiar?
That China goals is to become auto-sufficient.

Sound familiar?
Muh military


And the US should control what other countries sell in the Wassenaar agreement, because will be bad if US companies loose money to their competitors every time US deny a export license to a Chinese company.



Two decade ago.

They still goofed it up. China was not supposed to get the latest machine tools for semiconductors. I think the original goal was to keep China permanently two generations behind. And yet they almost sold EUV machines to China. If it wasn't for Trump (maybe with a little help from the CIA) it would have happened. The Western machine tool vendors just found the Chinese market irresistible and lobbied to drop the trade barriers.

The current effort to sabotage the Chinese semi industry with what are basically retroactive sanctions, which make machines China has already bought from them unserviceable is really crappy and shouldn't be allowed to happen. All this based on some artificial limit set by that government commission headed by Eric Schmidt which seems to think FinFET is some kind of magic amazing sauce (it isn't).

Here they were probably referring to Veeco vs Aixtron MOCVD tool sales in China. Two decades ago China had no commercialized mocvd. Today amec is either the largest or second largest mocvd maker.

Currently, Dutch company ASML is believed to still be providing such services to Chinese buyers. Per ASML’s financial report, during Q1, machine revenue from the Chinese market increased significantly from the previous quarter’s 39% to 49%.

This shows how far some of these mainstream media would spin the news out of context.

We have discussed this previously over here. The percentage increase in the Chinese market belies the fact that there was a 25% decrease in the quarter's Chinese revenue value (and a 50% value decrease in the rest of the market).
