The concept of chip in the information industry.

Hello in the chip industry chain, the upstream is the semi-conductor bending body material and semiconductor equipment; The midstream is chip design, wafer manufacturing, packaging and testing; Downstream application fields include automobiles, computers, manufacturing, security, communications, consumer electronics, industry, military industry, etc. China's R&D level is at the midstream level, and it is stepping up its efforts to get closer to the world's latest technology.

Chips are the foundation of modern information society for the following reasons:

1.Chips are the core components of various electronic devices such as computers, smartphones, and tablets, and play an important role in data storage, processing, and transmission.

2.The development of chip technology has promoted the development and popularization of the information industry, and promoted the application and innovation of emerging technologies such as the Internet, the Internet of Things, and artificial intelligence.

3.The high reliability, high density, low power consumption and other characteristics of the chip provide a more efficient, convenient and safe way of information exchange and management for modern society, and change people's living habits and working methods.

4.Chips are also widely used in national defense and military, aerospace, health care and other fields, and play a vital role in the country's scientific and technological level and comprehensive strength.

Therefore, it can be said that chips are one of the most basic and important technologies in the modern information society, and they have played an indispensable role in the development and progress of modern society.

Answer]: B silicon-based materials due to radiation resistance, high temperature resistance, high reliability and other characteristics, in the late 60s of the last century, gradually replaced germanium-based materials to become the mainstream semiconductor materials, at present, more than 95% of semiconductor chips and pre-god devices are made of silicon-based materials. Therefore, the formulation of item B is incorrect.

So, choose option B.

Item A: A chip is a semiconductor substrate containing an integrated circuit (the most commonly used is a silicon wafer), which is the physical carrier of an integrated circuit. Integrated circuit refers to the use of a specific manufacturing process to integrate the transistors, resistors, capacitors and inductors required in a circuit and the connections between components on a small silicon-based semiconductor wafer.

Item A is correct. Item C: Moore's Law refers to the fact that when ** is unchanged, the number of components that can be accommodated on an integrated circuit will double in width every 18-24 months, and the performance will also be doubled. Thus, Moore's Law shows how fast the number of transistors integrated on a chip increases.

Item c is correct. Item D: Chip manufacturing involves the research accumulation of multidisciplinary fields in academia and industry, including communication and network, microelectronics, automation, bioengineering, optoelectronics, power engineering and other disciplines. Item d is correct.

How should China's chips develop? This is indeed a topic with "weight", China's chip manufacturing is now lagging behind many countries, and even China's chip manufacturing process is far behind other countries, and it seems very difficult to overtake in corners. However, it is believed that China's science and technology will achieve a greater leap forward in this regard.

So how should China's chip manufacturing develop? Here are a few aspects worth discussing. <>

The first aspect: when chip manufacturing is limited by the United States, it is necessary to take the initiative here, which is not a zero-sum game, nor is it a matter of competition with each other, because now the chip business cannot compete with the United States at all, and take the initiative to find more possibilities in the international market, which is of great help to the rapid development of China's chip business.

The second aspect: pay attention to chip manufacturing, this aspect is a commonplace topic, if you do not pay attention to or do not invest money, then chip manufacturing will always lag behind others, but it is not easy to manufacture chips, it is also difficult to break through the technical bottleneck, fully mobilize the innovation ability of some domestic companies and high campuses, I believe that such a thing will also be solved. <>

The third aspect: China's company's demand for semiconductors accounts for nearly 25% of the world's total, but China's semiconductor production accounts for only 14 of them. And China's semiconductor products are still relatively backward, which can be seen that China's semiconductor chips are actually too dependent on other countries.

However, China's semiconductor chip market is very large, so big that any country does not want to give up, how to guide China's companies to enter the chip manufacturing industry has become a more urgent matter. Huawei is very powerful now, but it is not enough to rely on Huawei alone. <>

Finally, how to develop China's chip manufacturing industry, at this time, it is necessary to guide more funds, high-tech companies, and universities to participate, then the entire industry will enter a benign development stage, and China's chip manufacturing industry will have more right to speak.

Now basically, we have not mastered the high-end technology of the chip, which is very passive, especially the lithography machine and the architecture technology of the chip, which is the most important, and the design of the optical chip does not have much effect.

Therefore, there must be a breakthrough in the lithography machine and architecture, so that China's chip industry can develop.

If you want to develop Chinese chips, the most important thing is to master the key manufacturing technology of chips, make domestic lithography machines, and avoid the embarrassment of being able to develop chips but not being able to make them.

First of all: develop more of your own chips and improve your dependence on imported chips.

Secondly: introduce more advanced chip technology, take its essence to its dross, and accumulate more chip manufacturing experience.

Again: To further cultivate scientific and technological talents, there is a good saying, young people are strong and the country is strong.

In fact, Chinese chips should be more independent to develop their own technology and have a sense of innovation.

Question 1: DQuestion 2: A

The analysis of the test questions collapsed:

Question 1: As can be seen from the figure: during the period shown in the figure, the output value of China's IC industry has been rising, and the industrial structure has also undergone significant changes

The output value and structure of the manufacturing link are increasing, and the proportion of the design link increased the most from 2002 to 2003. Therefore, option d is correct.

Question 2: The design link of the IC industry is technology-oriented, and the packaging link is labor-oriented. The changes in the structure of the IC industry in the figure can reflect the transformation of the IC industry in the Pearl River Delta and Yangtze River Delta regions from labor-oriented to technology-oriented.
