As one of the most basic technologies, electronic technology is one of the key technologies supporting industries such as industry, automotive, and communications. 2018 is about to pass. As an electronic person, we are deeply aware of the rapid changes in the industry. If one word is used to describe the industry characteristics of the year, it is a "chip." More and more countries are paying attention to nuclear “core” technology. The chip industry involves materials, design, manufacturing, packaging, testing, etc. Any breakthrough in technology will bring revolutionary changes to the entire industry. The technology is also climbing steadily. In 2018, it can be said that the industry is developing at a high speed. The global electronics industry has also produced many technological breakthroughs. The following are the top ten “black technologies”.
People have been accustomed to the mode of electronic chips, that is, the independent working mode of computing and storage. But the way the human brain works is unified, and brain work is done through neurons and outstanding collaboration. In recent years, many research institutions around the world have begun to focus on brain-like chip technology, and have not been able to make breakthrough progress. In February 2018, MIT engineers designed an artificial synapse that precisely controls the intensity of the current flowing through the synapse, similar to the flow of ions between neurons, which is designed like a human brain. The working chip is very helpful. According to the relevant staff, the team has created an artificial synaptic chip made of silicon germanium. The synapse of the chip can recognize handwritten samples with high accuracy. This research is considered to be towards the mode. A key technological breakthrough in portable low-power neuromorphic chips for identification and other learning tasks.
Today, we are at the node of the development of second-generation semiconductor materials (silicon) and third-generation semiconductor materials. With the rapid advancement of information technology, semiconductor materials represented by silicon carbide (SiC) and gallium nitride (GaN). It is a key technology and material support for solid-state light sources, power electronics and microwave RF devices due to its superior forbidden band width, high breakdown electric field, high thermal conductivity, high electron saturation drift rate and strong radiation resistance. In March 2018, the Ministry of Science and Technology of China's Ministry of Science and Technology achieved a new breakthrough in the key technologies of high-quality third-generation semiconductor materials. According to the staff of OFweek Electronic Engineering Network, the project completed the scale of two-inch GaN self-supporting substrates. The production of high Al-component AlGaN-based deep ultraviolet light pump lasing, the development of a prototype of ultraviolet photodetector based on perovskite oxide material, achieved a new breakthrough in the early mass production of gallium nitride.
The single-mirror mirror is a high-precision aspheric optical mirror mainly used in the fields of earth observation, deep space exploration and astronomical observation. It is an important reference standard for measuring the high-performance optical level of the country. In August 2018, Changchun Opto-mechanical developed the world's largest caliber silicon carbide single mirror, marking China's entry into the international arena in this manufacturing field. It is reported that this 4m-order high-precision SiC aspheric mirror integrated manufacturing system technology will be applied to the national large-scale photovoltaic system. As an important scientific research institution in the country, Changchun Optical Machinery began researching optical grade silicon carbide ceramic materials in the 1990s and has achieved breakthrough results. In 2016, they successfully developed a single silicon carbide mirror with a diameter of 4.03 meters. Billet.
Sensors are almost everywhere. With the realization of the vision of “Internet of Everything”, future sensors will carry more black technology. For example, a naturally degradable pressure sensor researched by American scientists is full of highlights. According to the relevant staff, the sensor is portable and extensible, and it is very suitable for the medical industry, such as using this technology to customize a personalized rehabilitation program for many patients. With this technology, one can control the degradation of the sensor, keeping its life and tissue healing time uniform, and the sensitivity of the sensor is not affected. In addition to patient rehabilitation, it can be integrated into a miniaturized transmitter or receiver system with a very broad application prospect.
With the demand for the shape of electronic devices, flexible electronics has become a new technology choice. Electronic devices equipped with this technology can be bent and folded at will. Flexible electronic devices are more flexible than traditional electronic devices, and are more adaptable to the environment. Has become the most popular electronic research technology in recent years. How to apply flexible electronic technology to common equipment has become a hot topic today, and it is also the direction that scientists have been working hard. Hard work pays off. In May 2018, Tianjin University sent good news. The team of the National Key Laboratory of Precision Testing Technology and Instruments of Tianjin University successfully developed a flexible RF filter that can be directly applied to flexible electronics. It is a major technological breakthrough in flexible electronic equipment in China. This technology enables high-speed wireless communication between flexible electronic devices. For a long time, people’s fantasizing “folding” mobile phones have taken us one step further. If this technology is used in the mobile phone industry, the prospects are limitless.
5, The new topological insulator is expected to refresh the "world view" of the storage field
Storage technology is widely used in a variety of electronic devices, can be described as the "granary" of electronics. This year, researchers at the University of Minnesota led a new research project to explore a new type of topological insulator that involves magnetoresistance, which will improve computer computing and storage. According to relevant personnel, this magnetoresistive random access memory is gradually being applied in the field of computer storage. The material of this topological insulator is beneficial to further improve the energy efficiency of writing data of the magnetoresistive random storage electronic unit.
The lithography machine is known as the flower of industry and is as difficult to manufacture as the aircraft carrier. In November 2018, the national major scientific research equipment development project "super-resolution lithography equipment development" passed the acceptance, this equipment is a lithography machine, the lithography machine developed by China, the resolution reached 22 nanometers, can be used in the future Manufacturing 10 nanometer-level chips is a very significant technological breakthrough in China. Although it still has a gap with the world's top lithography machines (7nm or even 5nm), it is not easy to achieve such results.
As the basic unit of electronic circuits, logic devices can be applied in many places, but nowadays CMOS devices are the mainstream. In December 2018, Nature published a research paper on a generation of logic devices, including researchers at Intel, the University of California at Berkeley, and the Lawrence Berkeley National Laboratory. This paper describes a magnetoelectric spin-orbit (MESO) logic device invented by Intel. Compared to current CMOS devices and MESO devices, it is expected to reduce voltage by 5 times and energy consumption by 10-30 times. This technology research is expected to drive computing energy efficiency improvements across different computing architectures to drive performance growth.
The quantum Hall effect is a quantum effect version of the Hall effect, which needs to be observed under the extreme conditions of a low temperature and strong magnetic field. At this time, the Hall resistance and the magnetic field no longer have a linear relationship, and a quantization platform appears. The quantum Hall effect is one of the most important discoveries of the twentieth century, because there are many scientists who have won the Nobel Prize for researching related technologies. In December 2018, the research group of the Faculty of Physics of Fudan University published their research results in Nature. This is the first time that Chinese scientists have discovered the quantum Hall effect in three-dimensional space. It is reported that Prof. Xia Faxian's research group has observed the three-dimensional quantum Hall effect in the topological Dirac semi-metal cadmium arsenide material, and proved that the electron tunneling process has taken a key step from two-dimensional to three-dimensional, opening up a new brand. The research dimension indicates that this new study is a major step for human beings to take to the new scientific field.
As we all know, the chip process and performance are closely related. At present, there are not many manufacturers of energy-generating 7nm chips, and some research institutions have begun to study 3nm technology. Not long ago, scientists from a research team successfully developed a 0.7nm tungsten selenide diode, which means that this technology may break the semiconductor's 3nm process limit, and the chip can accommodate more diodes. The successful development of this 0.7nm tungsten disilicide diode will be a strong point for the industry to see the decline of semiconductor manufacturing process, which is of great significance.
The electronics industry originated in developed countries such as Europe and the United States. They have been leading other countries in technological research for many years, which is also their advantage. With the integration of global industries, many developing countries have begun to invest heavily in research on related technologies, including China. Scientists have not dared to face difficulties and overcome difficulties, and have achieved many achievements, including materials, equipment, manufacturing, etc. They are the core of the development of the electronics industry, and the most important talents, worthy of our respect and praise.
