Electronic parts using semiconductors are called semiconductor devices.
Many kinds of semiconductor devices have been developed in line with the expansion of application fields and the progress of electronic equipment. “Discrete semiconductors” are single devices with a single function, such as transistors and diodes. “Integrated circuits (ICs)” are devices with multiple functional elements mounted on one chip. Typical ICs include memories, microprocessors (MPUs), and logic ICs. LSIs raised the degree of integration of ICs. Classification by general function/structure is shown below.
