Mobile phone and computer chips are mainly made of silicon, an atomic crystal that does not dissolve in water or nicotinic acid and has a metallic luster. Silicon is found in crystals, opals, agate, quartz, and many other materials, but the silicon used to make chips mainly comes from quartz sand. Silicon is made into wafers, and then ions are added to turn it into a semiconductor, which can then be used to make chips. The entire process requires extremely high precision and is very technologically advanced.
What are the main materials composed of mobile phone and computer chips?
1. The main component of mobile phone and computer chips is silicon, a very common chemical element with the symbol Si. Silicon is found in rocks and sand, but to make chips, it needs to be refined into pure silicon wafers, and then ions are added to make it a semiconductor, which can then be made into transistors.
2. Silicon is also present in high amounts in the Earth's crust, reaching 25.7% of the total mass. It is usually extracted from silica, such as quartz sand, crystal, opal, etc. Silicon is generally grayish-black or black in color and has a metallic luster on its surface. It is insoluble in water and nicotinic acid, but it is soluble in alkaline solutions.
How are mobile phone and computer chips made?
1. First, silicon is extracted from silica, then purified to form wafers, which are then used to manufacture circuits. Ions can also be added to the wafers to transform them into semiconductors.
2. Once it becomes a semiconductor, the transistor can control the opening and closing of the circuit, and it can also be used as a data storage unit. Then, the data is written into it by a photolithography machine to make it a chip. Of course, there are many other processes involved in the whole process.
3. Wires can be added to semiconductors, along with thin films and BJTs, etc., and CMP technology can be combined to make chips. The chip manufacturing process is: design, lens manufacturing, packaging, and testing. The design and lens manufacturing process requires extremely high technical skills, and packaging and testing are also essential.
