The soul of electronic products

Semiconductor technology is the foundation of modern electronic devices, with billions of transistors integrated into chips, and the core of transistors is the PN junction. PN junction forms N-type and P-type semiconductors by doping different elements on silicon wafers, causing directional flow of electrons. The solid-state band theory based on quantum mechanics explains the conductivity of PN junctions. The application of quantum mechanics runs through the entire semiconductor manufacturing process, from atomic structures to chips. Chips are microcircuits formed by integrating thousands of electronic components (such as transistors, diodes, etc.) using semiconductor materials (such as silicon) through doping, photolithography, and other technologies. Based on the unidirectional conductivity of PN junctions and the switching control function of transistors, they achieve complex electronic functions and are the core components of modern electronic devices.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Chips and semiconductors: Almost all electronic technologies today involve the use of semiconductors. Chips are the general term for semiconductor component products, the carrier of integrated circuits, and the core components in computers and other electronic devices. PN junction: It is a transition layer in semiconductor materials that enables semiconductor conductivity. PN junction is the material basis of many components in electronic technology, such as semiconductor diodes and bipolar transistors. Principle of PN junction: The movement of electrons in PN junction follows the electronic transition law in quantum theory. On a complete silicon wafer, by doping phosphorus and boron atoms, an N-type semiconductor is formed on one side and a P-type semiconductor is formed on the other side. There is a transition layer, the PN junction, between the contact surfaces where the two are connected. At this time, the additional electrons of the N-type semiconductor will continuously flow to the vacancies of the P-type semiconductor, and the movement of electrons is called current. At this point, the PN junction is conductive. Almost all electronic technologies today.
