There are many reasons for the shortage of chips, and then I mainly discuss this topic with the relationship between supply and demand as the main core argument and the different relationship as the sub-argument.

First, the demand for mobile terminals has increased.

Due to the epidemic, many people stay at home, so the demand for mobile phones, tablet computers and game consoles has greatly increased, which has increased the demand for chips. Because the chip is one of the main cores of these mobile devices, the demand side is one of the main reasons.

Second, the demand for new industry chips.

Recently, the more popular manual driving technology, new energy and traditional fuel vehicles are also adding chips, which are transforming into intelligence. Although these chips are not high-end chips, they still need to be produced and belong to one kind of chips, so the demand for chips in the automobile industry is far greater than what the market can provide.

Third, the production time is long.

If the production capacity of the product is far below the demand. The main reason is that it can't be produced, because chip production needs strong technical accumulation. Without decades of accumulation, it is impossible to produce chips in a short time. Not that you can build a factory with money, but that he needs you to accumulate technology for a long time. But there are not many manufacturers who can produce chips now. It takes ten weeks from silicon wafer to chip, so less production time means less chip damage.

Fourth, problems in production.

Because of the epidemic, many enterprises can't start work, even if they start work, individual employees can. As a result, employees can't fully go online, and the production capacity of enterprises will be greatly reduced, especially for some technical experts or people in the technical field. If there is no way to go to work, it will have a huge impact on the production capacity of enterprises.

Fifth, the unreasonable attack of the United States. Due to the unreasonable attack of the United States on Huawei, Huawei had to hoard chips in advance to meet the needs of future production development, and the number was huge, which greatly reduced the number of chips entering the market, so there are very few chips now.
