A semiconductor is a substance with a conductivity between that of a conductor and an insulator. It is not very conductive in a pure state, but its conductivity can be adjusted by adding impurities (doping) or changing the temperature. The typical representative of semiconductors is silicon, which is widely used in the manufacturing of electronic components. Semiconductor technology is the cornerstone of modern electronic devices, such as smartphones, computers, digital cameras, etc., all rely on semiconductor chips. In addition, semiconductors are also very important in the energy field, such as semiconductor materials, which are the core of solar cells

Chip is a general term for semiconductor component products. In electronics, it is a method of miniaturizing circuits (mainly including semiconductor devices and passive components) and often manufactured on the surface of semiconductor wafers. Also known as integrated circuit, microcircuit, or micro

Faced with the increasingly high integration of hardware platforms and more and more complex electronic systems, the PCB layout should have a modular thinking, which requires the use of modularity in the design of hardware schematics and PCB wiring. , Structured design method. As a hardware engineer, on the premise of understanding the overall architecture of the system, first of all, we should consciously merge modular design ideas in the schematic diagram and PCB wiring design, combined with the actual situation of the PCB, plan the basic idea of PCB layout.

Every time through AI flash, Guojin Securities said that semiconductor equipment parts play an important role in the industrial chain, with a large number, a wide variety and obvious market fragmentation characteristics

Chip is the general term of semiconductor component products. Chip is also called integrated circuit and IC. What material is the chip mainly composed of? Let's have a look!
