A chip is an integrated circuit made up of millions of tiny transistors. It is the heart of electronic devices and is used to process and store data. Chips can perform various functions such as computing, communication, and control. They are widely used in computers, mobile phones, automobiles, home appliances and other fields.
The fabrication of the chip requires first designing the circuit diagram, then transferring the circuit diagram to the silicon wafer using lithography technology, and forming the transistor through chemical and physical processes. The development trend of chips is to continuously increase integration, improve performance and reduce size.
