Integrated Circuit Industry：

Since Texas Instruments (TI) invented the integrated circuit (IC) in 1958, with the development of silicon plane technology, two important integrated circuits, bipolar type and MOS type, were invented successively in the 1960s, which marked a quantum and qualitative leap in the era of electronic complete machine manufactured by electron tube and transistor. Create an unprecedented strong penetration and vitality of the emerging industry integrated circuit industry. 

Reviewing the development history of integrated circuit, we can see that the phrase "from circuit integration to system integration" is the best summary of the development process of IC products from small scale integrated circuit (SSI) to today's very large scale integrated circuit (ULSI) since its invention more than 40 years ago. That is to say, the development of integrated circuit products has gone through the process from the traditional System on board to System on a chip. In this historical process, in order to adapt to the development of technology and market demand, the industrial structure of the world IC industry has undergone three changes.
