Both directions are good
First of all, there is no essential difference between the two, microelectronics covers the direction of integrated circuits, which can be chosen according to their own interests, without entanglement; Secondly, from the perspective of the future development trend of disciplines and technologies, comprehensive professionals are in short supply. The so-called comprehensive professionals refer to talents who have comprehensive and extensive knowledge system structure and foundation, and have expertise in certain aspects of specific fields such as materials, physics, devices, circuits, systems, algorithms, etc. Therefore, whether the selection of microelectronics, or the selection of integrated circuits is not too important, the important thing is to build and their own knowledge system, train their own strengths!
Microelectronics and integrated circuits are relatively cutting-edge disciplines, microelectronics is more abstract, huge development space, depending on your hobby, I think learning microelectronics development space is huge, is more abstract, to have a certain imagination.
