Chips, a relatively unfamiliar word in our daily lives, hides shocking secrets. They seem to be just an ordinary part of electronic devices, but they are affecting our lives and society at an alarming rate. The smartphones, computers, cars and even home appliances we are familiar with are inseparable from these seemingly ordinary chips, but the secrets behind them are little known.
How ordinary chips work: how to process and store information
We need to understand the basic structure of a common chip. A normal chip is made up of hundreds of millions of tiny transistors, each of which can control and transmit current. These transistors are connected to each other to form a vast network, which enables the chip to perform complex information processing and storage.
When current passes through the transistor, it is transmitted to the circuitry inside the chip, where it undergoes a series of logic operations and processing to produce an output. This process is the basis for information processing by ordinary chips. Information is transmitted between different transistors through changes in voltage, which can represent different binary bits (0 or 1), enabling data storage and processing.
The information storage in the ordinary chip is realized by the memory unit. A memory cell is a specific part inside the chip that holds data for later use. The most common memory units are latches and flip-flops. These memory cells are capable of storing information about one or more binary bits and reading them out when needed. Through different voltage transmission and control, ordinary chips can realize long-term storage and reading of data.
The working principle of ordinary chips is based on the principles of digital logic circuits and Boolean operations. By using logic gates, transistors can perform basic logic functions such as and gates, or gates and nongates. The combination of these logic gates can lead to more complex logic circuits that enable a variety of complex computational and processing tasks. These logic circuits inside ordinary chips are able to process and convert the input signal specifically through tiny switches or combinations of switches, and finally produce the desired output result.
In addition to the logic circuits, ordinary chips also contain a clock system and a control unit. A clocking system is used to synchronize the various circuits and transistors inside the chip, ensuring that they operate according to a set time sequence. The control unit is responsible for managing the operation and control of the entire chip, and completing the corresponding processing and operation according to the requirements of the input signal and logic circuit.
Materials for Common Chips: Why Silicon is the Mainstream Choice
Silicon has excellent semiconductor properties, which is one of the main reasons why it is the mainstream choice. A chip is made up of many transistors, and transistors are one of the basic components of electronic technology. The uniqueness of silicon is that its electronic structure allows it to conduct and de-energize both under certain conditions, which is often referred to as semiconductor properties. This feature allows the silicon chip to work under the control of current to realize the storage and processing of data. Compared with other materials, such as metal, the semiconductor properties of silicon are more suitable for the needs of chips, so that the chips can work stably and reliably.
The abundance and reliability of silicon materials are also important reasons why silicon has become the mainstream choice. Silicon is the second most abundant element on Earth and is widely found in deserts, rivers, and rocks. This means that the cost of obtaining silicon is relatively low, and the amount of silicon is relatively stable. At the same time, the reliability of silicon materials is unmatched by other materials. The stability of the silicon crystal structure enables the chip to run stably for a long time, and the silicon material is highly resistant to external interference and changes, and can provide good electrical characteristics.
Silicon also has good processability, which is a key factor in its mainstream choice. As the core of microelectronic products, chips need to be manufactured through precise processing technology. Silicon materials can be finely processed by controlling temperature and pressure during processing, and silicon materials are not easy to be polluted, which is conducive to improving the manufacturing quality and stability of chips. At the same time, silicon materials can also be well combined with other materials to form various composite materials to meet the needs of different application fields.
The manufacturing process of common chips: from wafer processing to packaging and testing
We need to understand the process of wafer processing. Wafers are the basis of chip manufacturing, and they are wafers made of pure silicon material. Wafer preparation requires multiple steps, including single crystal growth, dicing, polishing, and more. In the process of single crystal growth, the silicon material is placed in a high-temperature molten state, and the silicon material gradually forms a uniform single crystal by controlling the temperature and internal and external pressure. Subsequently, the single crystal is cut into thin slices, which are familiar wafers. Finally, the wafer is polished on a polishing machine to remove surface irregularities and contaminants to obtain a smooth wafer surface.
Next, the wafer needs to undergo a process of lithography and etching. In the lithography process, a special coating and lithography machine are used to project the designed circuit pattern onto the wafer. Then, the chemical etching method is used to remove the area that has not been **, and the convex structure formed by the circuit pattern is retained. This step is repeated many times, gradually forming a complex circuit structure.
Next is the processing process of the chip. At this stage, the chip is delicately processed and doped through multiple processes such as oxidation, diffusion, and ion implantation. These processes are mainly used to change the conductivity of silicon materials and form basic components such as transistors and capacitors. These basic components are combined to form a circuit with a specific function.
Then there is the metallization process. In this step, a layer of metal, usually aluminum or copper, is formed on the surface of the chip. Then, photolithography and etching techniques are used to shield the metal layer at the point where it needs to be connected and connect to the circuitry inside the chip. In this way, the internal circuitry of the chip is connected to the outside world.
Chips need to be packaged and tested. Encapsulation is the attachment of a chip to wires and other external components and encapsulation in plastic or ceramic packaging to protect the chip from damage. During the testing process, various performance tests are carried out on the chip to ensure that it meets the design requirements and quality standards.
The field of application of ordinary chips: ubiquitous electronics
The application of ordinary chips in the field of communication has been very common. Our common mobile phones are the best example of this. Whether it's making **, texting, surfing the Internet, or taking photos and videos, all these functions are inseparable from the ordinary chip built into the mobile phone. It is responsible for the transmission and conversion of data and signals, making communication faster and more stable. At the same time, the application of ordinary chips has also been extended to the field of wireless network communication, so that wireless routers, wireless headphones and other devices can better interact with other devices.
Ordinary chips are also widely used in the entertainment field. Entertainment equipment such as TVs, stereos, and game consoles are inseparable from the operation of ordinary chips. Image processing chips in TVs, audio processing chips in audio, graphics chips in game consoles, etc., all play an important role. They can quickly calculate and process complex algorithms and thousands of data, bringing users a more realistic and immersive entertainment experience.
Ordinary chips also play a huge role in the field of home life. Many electronic devices in modern homes, such as refrigerators, washing machines, air conditioners, etc., are equipped with ordinary chips. Through the control of smart chips, these appliances are able to automatically detect environmental parameters and intelligently adjust them according to user needs. For example, refrigerators can automatically adjust the temperature, washing machines can automatically choose the appropriate washing program according to the material and quantity of clothes, and air conditioners can intelligently adjust the cooling or heating mode according to changes in indoor temperature. These convenient features not only improve the quality of life, but also save energy and time.
In the field of transportation, ordinary chips also have a wide range of applications. Cars are one of the main ways for modern people to travel, and the application of ordinary chips in cars is indispensable. From engine control to in-car navigation and in-car entertainment systems, the operation of ordinary chips is inseparable. They enable precise data processing and signal transmission to improve driving safety and driving experience. In addition, with the development of autonomous driving technology, the role of ordinary chips in the automotive field will become more and more important, providing solid support for the development of intelligent transportation.
