Source: Wisdom Microelectronics Original Author: Peng The reason chips are called chips is due to semiconductor technology; the biggest difference between chip systems and board-level systems is the use of semiconductor physical devices. Semiconductor devices are the foundation of chip companies. Even for chip companies or chip engineers, “semiconductor physics” is a daunting term. This … Read more
Compound semiconductors have excellent performance and a broad development prospect. Compound semiconductors mainly refer to second and third generation semiconductors such as Gallium Arsenide (GaAs), Gallium Nitride (GaN), and Silicon Carbide (SiC). Compared to the first generation of elemental semiconductors, they are significantly superior in high-frequency and high-temperature performance. Gallium Arsenide: It features high frequency, … Read more
A semiconductor laser is a device that generates laser light through the principle of PN junction stimulated emission. Its excitation methods include electrical injection, optical pumping, and high-energy electron beam excitation. When designing the driving circuit for semiconductor lasers, it is essential to understand its working principle, but more importantly, to study its working characteristics. … Read more
With the continuous development of electronic information technology, semiconductor materials have undergone several iterations.Currently, the third-generation semiconductors represented by GaN and SiC have become a “battleground” for countries around the world, widely used in the manufacture of various electronic and optoelectronic devices.However, in recent years, new application scenarios such as 6G communication, super-fast charging for … Read more
Currently, there are five confirmed growth engines in the semiconductor industry, which are:① Mobile terminals, such as smartphones, smartwatches, wearable devices, laptops, and tablets;② High-performance computing (HPC), also known as supercomputing, which can process data and perform complex calculations at high speeds on supercomputers;③ Autonomous vehicles;④ Internet of Things (IoT), such as smart factories and … Read more
In our daily work and life, we often use various electronic or electrical products, such as computers, mobile phones, televisions, refrigerators, washing machines, etc. If we take these products apart, we will see a piece of green board similar to the one below. Sometimes it can be blue or black. Everyone knows that this green … Read more
Source: Semika Original Author: Semika This article introduces the process of lithography, the basic principles of lithography machines, as well as the characteristics and applications of various lithography machines. The Process of Lithography Lithography is a pattern transfer technology that transfers the graphics on a mask to a silicon wafer coated with photoresist (also known … Read more
In the modern world, no one can say they are unrelated to “semiconductors.” Semiconductors sound rigid and cold, but they are not just a concern for engineers in scientific parks; the smartphones you swipe, the computers you use, the televisions you watch, and the speakers you listen to all contain semiconductor components. It can be … Read more
Source: Content from Chuangfuhui, thank you! What Are the Differences Between Semiconductors, Integrated Circuits, and Chips In today’s rapidly advancing technological era, we often hear the terms semiconductor, integrated circuit, and chip. They seem to be the magic of the tech world, driving innovation and development across various industries. But do you know their differences … Read more
