Chip production is a problem in many countries, so what is the internal structure of the chip?

Chips are used in almost all electronic products in our daily life, and the role of chips in electronic appliances is like the role of the brain in the human body.

The manufacturing technology of the chip is very cutting-edge, and the knowledge of many fields is integrated, but what is the inside of the chip?

Let's use a more typical and common chip to introduce it to you.

The first part is the appearance of the chip, the front side is the number and model of laser marking, and the reverse side is the cut mark, which is cut after the whole plate is tinned. Underneath the outer layer are a number of components, consisting of semiconductors and power inductors.

The bottom of the chip is the pad and tin plating, and the thickness is only 16um once. The size of the electronic devices inside the chip is very small, the size of the whole chip is only 3*, the size of the power inductor device is 2*, and the size of the semiconductor is the smallest. The distance between each two soldering ports of the chip is only 1 nanometer at most.

Because the size is too small, and the position of the circuit must be arranged in addition to the electronic components, the production process is too cumbersome, and the precision requirements for the production machine are also very high, so the production of chips has always been a problem in many countries around the world.

It takes nearly 20 years for a developing country, such as China, to build a chip production chain from scratch, so for many developing countries, chips are imported.

The best countries in chip production are the United States and Germany, which are the first countries in the world to start producing chips, and they have the best technical talents and the most complete and advanced chip production chain in the chip field, and have a certain monopoly position in the chip market.

Chips are also called integrated circuits or microcircuits, and the world's first integrated circuit was born in 1958 by American Jack. Kirby, who was awarded the Nobel Prize 42 years after the invention of integrated circuits, would not be the semiconductor industry it is today.

Integrated circuits can be divided into digital integrated circuits, analog integrated circuits, and a mixed-signal integrated circuit according to analog or digital. Digital integrated circuits are good at transmitting information, and analog integrated circuits are more used in control circuits.

Most chip constructions are extremely complex on the inside.

On the reverse side is a cut mark, which is made by cutting the whole plate after tinning. Underneath the outer layer are a number of components, consisting of semiconductors and power inductors.

The internal structure of the chip is complex, and the circuit transmission is even more complex.

In addition to silicon, one of the most important materials needed to make chips is metal. So far, aluminum has become the main metal material for making internal accessories for processors, while copper is gradually being phased out, and there are a number of reasons why the electromigration characteristics of aluminum are significantly better than copper at the current chip operating voltage. The so-called electromigration problem refers to when a large number of electrons flow through a conductor, the atoms of the conductor material are hit by electrons and leave their original positions, leaving vacant spaces, and too many vacancies will cause the conductor wires to be disconnected, and the atoms that leave the original position stay in other positions, which will cause short circuits in other places and affect the logical function of the chip, and then cause the chip to be unusable.

The internal structure of the chip is complex, so it is difficult.

All of them are made of silicon, plus some special electronic components.

At the current chip operating voltage, the electromigration properties of aluminum are significantly better than those of copper. The so-called electromigration problem is when a large number of electrons flow through a conductor.

After the collection of the necessary raw materials, some of these raw materials need to be pre-treated. As the most important raw material, the processing of silicon is crucial. First, the silicon feedstock is chemically purified, a step that brings it to the level of feedstock that can be used in the semiconductor industry.

In order for these silicon feedstocks to meet the processing needs of integrated circuit manufacturing, they must also be shaped, which is done by melting the silicon feedstock and then injecting liquid silicon into a large high-temperature quartz container.

Inside, it's a collection of all kinds of originals.

In fact, it is determined by the arrangement of silicon elements.

A high level of technology is required inside the chip.

Chip is a very broad concept, it is not only used in computers, in many occasions there will be different kinds of chips, such as chips used in computers, chips used in displays, lights and so on. The chip is actually what we call a MUC (microcontroller), which is a tiny system unit that can inherit thousands or even tens of millions of parts. A computer chip is a chip used in a computer, and a computer chip is actually an electronic part, which contains thousands of resistors, capacitors and other small components.

There are a lot of chips on the computer, memory modules.

The black strip on the last piece is a chip, there are many chips on the motherboard, hard disk, graphics card, etc., and the CPU is also a computer chip, but it is more complex and more sophisticated than ordinary computer chips.

So why should China vigorously develop the chip industry for the sake of hand collapse? The main reason is that chip integrated circuits are the cornerstone of Xinyu Acorn Society, and they are also an important foundation of information technology. It should be said that the high-quality development of the chip industry.

It is related to the development of the modern information industry and industrial chain. "Thirteenth Five-Year Plan.

The development of China's integrated circuit industry is generally very impressive, and the scale of the industry is growing. According to the estimation of China's semiconductor industry, China's integrated circuit sales revenue will reach 884.8 billion yuan in 2020, with an average growth rate.

reached 20%, which is three times the growth rate of the global industry in the same period. Breakthroughs have also been made in technological innovation, and the current manufacturing process, packaging technology, and key equipment materials have been significantly improved. The strength of the enterprise has been steadily improved, and a number of new leading enterprises have emerged in the industrial chain of design, manufacturing, packaging and testing.

In general, the chip industry and the integrated circuit industry are the first in China.

It attaches great importance to and has issued policies to promote the high-quality development of the integrated circuit industry and the software industry, and comprehensively optimized and improved the relevant environmental policies for the high-quality development of the chip and integrated circuit industry.

Answer hello. Chip is a general term for semiconductor component products, also known as microcircuits, microchips, and integrated circuits. Refers to a silicon wafer containing an integrated circuit, which is small in size and is often part of a computer or other electronic device.

Semiconductor is a general term for a class of materials, integrated circuits are a large collection of circuits made of semiconductor materials, and chips are products formed by different types of integrated circuits or single types of integrated circuits.

If the CPU of the processor is compared to the heart of the entire computer system, then the chipset on the motherboard is the torso of the entire body. For the motherboard, the chipset almost determines the function of the motherboard, which in turn affects the performance of the entire computer system, and the chipset is the soul of the motherboard.

Do you know how chips are made?

The power management chip manufacturing process generally includes power chip design, chip production, packaging production, testing and other links, among which the chip production process is particularly complex, first of all, integrated circuit chip design, according to the needs of the design, the generated "pattern", if you want to do the power scheme, I can recommend it to you.

To sum up, it is the importance of chips and the manufacturing pattern.

The chip belongs to the foundation of the foundation, and the core of all kinds of electronic products we use is a chip. The world's chips are made by the Netherlands' high-end lithography machines, and the West still has strong technology.

Chips are not only used in mobile phones, computers and other equipment, but also widely used in the military, drones, communication towers and other fields, of course, very important, China's chips mainly rely on foreign imports, but in recent years we can also make our own chips.

In the information age, chips are widely used in various electronic products and systems, and are the core cornerstone of high-end manufacturing! Without chips, the development of many high-end industries in China will be restricted, so it is very important! At present, the United States still dominates the field of 5G chips, but at the same time, Chinese chipmakers are also seeking greater development.
