Solid state electronics and microelectronics?

Microelectronics is a branch of electronics, which mainly studies the motion law and application of electrons or ions in solid materials, and uses it to realize the function of signal processing. It aims to realize the integration of circuits and systems. The circuits and systems realized in microelectronics become integrated circuits and integrated systems, which are miniaturized; In microelectronics, the space size is usually expressed in microns（ μ m，1 μ M = 106 m) and nano (nm, 1nm = 109 m).

Electronics is a science and technology whose main purpose is application. It mainly studies the characteristics and behavior of electrons and the physics of electronic devices. Electronics involves many scientific categories, including physics, chemistry, mathematics, material science and so on. Electronic technology is the science of applying the principle of electronics to design and manufacture circuits and electronic devices to solve practical problems.

The employment prospect of microelectronics major is relatively good. Such talents in China are scarce and the salary is high, but the requirements for people's education and ability are also high.
