At the end of the 1940s, the first semiconductor triode was born in the world. With its characteristics of small size, light weight, power saving, and long life, it was quickly used by various countries and replaced electronic tubes in a large range. In the late 1950s, the first integrated circuit appeared in the world. It integrated many electronic components such as transistors on a silicon chip, making electronic products smaller. Integrated circuits have rapidly developed from small-scale integrated circuits to large-scale integrated circuits and ultra-large-scale integrated circuits, thereby enabling electronic products to develop in the direction of high efficiency, low consumption, high accuracy, high stability, and intelligence.
