Raw materials are as follows:
1. Silicon: The main raw material for chip manufacturing is monocrystal silicon, which is a silicon material refined with high purity and can precisely control the size and shape of electronic devices.
2. Proportional Charge Oscillator (PLL) : PLL is a circuit that can produce a high-precision clock signal and is an interface between digital circuits and analog circuits.
3. Wafer: Wafer is a disc-shaped material made of silicon wafers, in the chip manufacturing process, wafer as the basic material of the chip, the diameter of the standard wafer is generally 200 mm or 300 mm.
4. Background material: The chip background material is generally used to fill the space inside the chip, protect the circuit inside the chip and control the charge movement inside the chip.
5. Metal wire: Metal wire is mainly used to connect different circuit components inside the chip to complete the circuit connection inside the chip.
6. Packaging material: The chip packaging material is one of the materials necessary to package the chip into a complete electronic device, through the packaging material can protect the chip, and make the chip have reliability and long-term stability.
The above are some commonly used chip raw materials, chip manufacturing requires the use of high-precision materials and production processes to ensure the performance and stability of the chip.
The raw material of the chip is a wafer, which is composed of silicon, and silicon is extracted from quartz sand. A chip is made up of hundreds of microcircuits connected, small in size, and the chip is filled with microcircuits that generate pulsed current.
