To think people get paid for writing this.


For international companies China is a gold mine, a cow whose udder does not run out and unless there is a shooting war they will not abandon that market so easily, they will lobby the hell out of all the politicians to continue selling in that market .

This is from an international organization on some semiconductor technology. I will leave you guys to fill blanks as you wish ......

Only three European surnames, what organization is this.

A bit of Chinese history, this is probably one of China first self-made E-Beam lithography system, I think this system date back to 2003 probably in a time that they were having a lot of problems importing this kind systems from Japan, U.S. or Europe. That was until export controls on this kind of systems was relaxed. Who knows how far they would have develop this.


Electron beam nano-exposure system DY-2000 system overview:
Electron beam nano-exposure system is a special equipment for micro processing, which integrates various high technologies such as light, machine, electricity, vacuum and control.

System composition : electron optical system (scanning electron microscope), pattern generator, precision workpiece table, control system, vacuum system, precision power supply.
main application:
1 : Research on semiconductor devices: microwave transistors, single-electron transistors, quantum dots, superconducting rings, etc.
2 : Research on optoelectronic devices: special gratings, Fresnel zone plates, crystal detectors, optical waveguides, optical integrated devices
3 : Micromechanical research: micro-nano electromechanical systems, micro-channels, micro-sensors, 3D microstructures
4 : Consumer Electronics Research: Holographic Optical Components, Next-Generation DVD Lights, Optical Sensors, Magnetic Heads, Surface Acoustic Wave Devices
5 : Other research: non-production mask fabrication, pattern position calibration and CD measurement
Nano pattern generator DY-2000 is the core component of electron beam nano exposure system DY-2000 , which is independently developed and produced by Institute of Electrical Engineering, Chinese Academy of Sciences. Incorporating the latest achievements of digital signal processing in recent years , the high-performance digital signal processor (DSP) is used to split the unit graphics to be exposed into lines and dots , and then the digital quantity is converted into high-precision through the optimally designed digital-to-analog conversion circuit . The analog quantity of the SEM drives the deflector of the scanning electron microscope to realize the scanning of the electron beam.

China has declared 18,728 patent families, accounting for 39.9 percent of the world's total, followed by the U.S. at 34.6 percent and the South Korea at 9.2 percent. /CFP

Jiangfeng Electronics: Domestic substitution of some raw materials has been achieved​

Jiwei Net News (Text / Chen Wei) On June 10, Jiangfeng Electronics pointed out in the newly disclosed investor relations activity record that in recent years, the company has gradually deployed its shares mainly by participating in companies, implementing fundraising projects and other investment projects. In the field of upstream raw materials, domestic substitution of some raw materials has been achieved.

At the same time, it also disclosed that at present, the parts produced by the company mainly include transmission cavity, reaction cavity, chamber body, ring assembly (ring), cavity shield (shield), protection disc (disc), cooling disc body (cooling arm), heating plate (heater), gas distribution plate (shower head), gas buffer plate (block plate), etc.; materials include metal (stainless steel, aluminum alloy, titanium alloy), non-metallic (ceramic, Quartz, silicon, polymer materials), etc.

According to the application customers, the components produced by Jiangfeng Electronics can be divided into two categories: one is used in chip production equipment manufacturers, including process components and cavities, etc.; the other is used in integrated circuit manufacturers. Critical process components in the circle manufacturing process.

In recent years, Jiangfeng Electronics has seized the opportunity for the growth of parts and components in a timely manner, actively deployed parts and components, and strived to expand the scale of production. At present, three parts production bases have been built in Yuyao, Zhejiang, Fengxian, Shanghai, and Shenbei, Shenyang. A full-process, full-process production system for the production of parts and components such as ultra-precision machining, special welding, surface treatment, and super-purification cleaning.

The patent abstract shows that the present application provides a quantum chip and a quantum computer, which relate to the field of quantum computing technology, so as to solve the problems of difficulty in manufacturing quantum chips and low yield. The quantum chip provided by this application includes: a substrate, M sub-chips, a coupling structure and a cavity mode suppression structure; each sub-chip includes N qubits, and the M sub-chips are arranged on the board surface of the substrate at intervals; the coupling structure is used to realize the M sub-chips. The interconnection between chips; the cavity mode suppression structure is arranged at the edge of each sub-chip and/or in the gap between the M sub-chips, and is used to increase the cavity mode frequency of the quantum chip; wherein, M is a positive integer greater than 1, N is a positive integer greater than or equal to 1.

In the quantum chip provided in this application, the quantum chip is composed of M sub-chips, which can effectively reduce the difficulty of production and improve the production yield; and, when a quality defect occurs in a certain sub-chip, it will not cause quality defects. The resulting problems are high cost and waste of resources. (Proofreading/Small such as)
