The relationship between wafers and chips

Because of the U.S. ban on ZTE, the topic of "chips" has become very popular. The most important weapon of the country is at the mercy of others. We must learn from this painful experience and not allow such an incident to happen again. However, some people with ulterior motives are clamoring for "imposing heavy taxes on American chips." Those who say this are either enemy agents or extremely irresponsible people.

Chip, also known as microcircuit, is the general name for semiconductor component products. It refers to the silicon wafer containing integrated circuits. It is small in size and is often used in computers. or part of other electronic equipment.

Wafer refers to the silicon wafer used in the production of silicon semiconductor integrated circuits. Because it is circular in shape, it is called a wafer. (Recommended learning: PHP video tutorial)

The silicon wafer is processed to form a wafer, and then packaged to form a chip.

The chip is composed of N multiple semiconductor devices. Semiconductors generally include diodes, transistors, field effect transistors, low-power resistors, inductors, capacitors, etc.

Silicon and germanium are commonly used semiconductor materials. Their properties and materials make them easy to use in large quantities and at low cost for the above-mentioned technologies. A silicon wafer is composed of a large number of semiconductor devices. Of course, the function is to form a circuit of semiconductors as needed and exist in the silicon wafer. After packaging, it becomes an IC.

Wafer refers to the silicon wafer used in the production of silicon semiconductor integrated circuits. Because its shape is round, it is called a wafer; various circuit element structures can be processed on the silicon wafer to become IC products with specific electrical functions. The raw material of the wafer is silicon, and there is inexhaustible silicon dioxide on the surface of the earth's crust. Silica ore is refined in an electric arc furnace, chlorinated with hydrochloric acid, and distilled to produce high-purity polysilicon with a purity as high as 0.99999999999.

The wafer manufacturing plant then melts the polysilicon, mixes a small grain of silicon crystal seed into the melt, and then slowly pulls it out to form a cylindrical single crystal silicon ingot. Since the silicon crystal rod is gradually formed from a small crystal grain in the molten silicon raw material, this process is called "crystallization". After the silicon ingot is ground, polished and sliced, it becomes the basic raw material of the integrated circuit factory - silicon wafer, which is the "wafer".

ARM is a chip design company. It does not produce chips. Instead, it licenses its design solutions to other semiconductor manufacturers for production and manufacturing by them.

Of course the chip industry is not that simple. To produce a chip requires thousands of processes, so some people say that 'making chips is more difficult than making atomic bombs'.
