36A chip is a thin sheet made of silicon material, which is only half the size of a fingernail. A chip is made up of hundreds of microcircuits connected together. It is very small and is covered with microcircuits that generate pulsed current. Computer chips use these microcurrents to complete the operations required to control computers, automation devices and other various equipment. The circuits in the chip are very small and the current used is also very small, so the chip is also called a microelectronic device. The main chips in microcomputers include microprocessor chips, interface chips, memory chips, etc.
The chip production process usually includes design, mask making, wafer preparation, photolithography, etching, deposition, cleaning and testing, packaging and testing. These steps are based on the characteristics of semiconductor materials and the principles of microelectronics technology. Using photolithography, etching, deposition and cleaning, the circuit pattern is transferred to the semiconductor material and a multi-level circuit structure is formed. These circuit structures are connected through metal lines and insulating layers to form a complete chip circuit. Finally, chip packaging and testing ensure the reliability and performance of the chip.The working principle of the chip mainly depends on the basic component of the transistor.
A transistor consists of three regions: a p-type semiconductor, an n-type semiconductor, and a p-type semiconductor (or an n-type semiconductor, a p-type semiconductor, and an n-type semiconductor). When a positive bias is applied, an electric field is formed between the p region and the n region, and charges can flow from the p region to the n region along this electric field; when a negative bias is applied, charges cannot flow through. The working principle of a chip is to use components such as transistors to build digital circuits to achieve functions such as logical operations, data storage, and signal amplification.
With the continuous advancement and development of technology, the design and manufacturing level of chips is also constantly improving, and their performance and reliability have also been further improved. The development of integrated circuits has gone through stages such as large-scale integrated circuits (LSI), very large-scale integrated circuits (VLSI), extremely large-scale integrated circuits (ULSI), and GLSI. The progress of each stage has enabled chips to encapsulate more circuits, increase the capacity per unit area, reduce costs, and increase functions.
