What is the chip mainly composed of?

Mobile phone computer chip raw material is wafer, wafer composition is silicon, so mobile phone computer chip is mainly composed of silicon.

Silicon is refined from quartz sand, the silicon element is purified in wafers, and these pure silicon are then made into silicon rods, which are used to make integrated circuits.

The process of implanting ions into the wafer to produce the corresponding P and N semiconductors will change the way the doped region conducts electricity, so that each transistor can turn on, off or carry data.

The complete process of chip making includes chip design, chip making, package making and testing, among which the chip making process is particularly complex.


The chip is mainly composed of monocrystalline silicon.

The chip is processed from silicon wafers, the silicon element is purified (99.999%), and then the pure silicon is made into silicon rods, which become the material of quartz semiconductor for manufacturing integrated circuits, after photographic plate making, grinding, polishing, slicing and other procedures, the polycrystalline silicon is melted out of the monocrystalline silicon rod, and then cut into a thin wafer. And then use the lithography machine, etching machine, ion implantation machine, packaging lithography machine and other equipment to produce a chip, the chip is mainly silicon crystals and metal lines, the external plastic sealing shell.
