The history of electronic components is the history of concentrated electronics.Electronic components are components of electronic components and small machines and instruments, which are often composed of several parts and can be used in similar products; It often refers to some parts of electrical appliances, radios, meters and other industries, and is a general term for electronic devices such as capacitors, transistors, spring wires, and so on. Common are diodes and so on.

When the external conditions of semiconductor materials change, their conductivity will change significantly. Semiconductors are widely used in integrated circuits, solar cells, computer chips and other fields, and are the basis of modern electronic technology ‌.
