Semiconductor is actually a kind of material, but the design and processing technology of this material are very demanding and widely used. At present, most electronic products, such as computers1.11381.43%, and the core units in mobile phones or digital recorders are inseparable from semiconductors, which can be said to be basic accessories in the field of scientific and technological innovation.

The research threshold of scientific and technological enterprises such as semiconductors is high, and the emerging enterprises that have not yet grown up are mixed and speculative, and their ability to resist wind and waves is poor in development and process. Everyone should take the form of investment funds to reduce the risk of investing in individual stocks.

1, China semiconductor (99000 1. CSI)
