Differential microelectronics is the study of miniaturization of electronic devices and circuits.
Integrated circuit, narrowly speaking, refers to chip design, broadly speaking, including chip-related materials, devices, process manufacturing, design, EDA, etc.
Since continuous miniaturization is an important feature of integrated circuits, integrated circuits are a major part of microelectronics.
The development prospects of microelectronics are better, and the scope of microelectronics will be slightly larger than that of integrated circuits, such as MEMS, which also has a part of microelectronics.
