Understanding Dry Etching Technology in the Semiconductor Industry

Currently, many semiconductor devices employ mesa device structures, which are predominantly created through two types of etching: wet etching and dry etching. While the simple and rapid wet etching plays a significant role in semiconductor device fabrication, it has inherent drawbacks such as isotr......

Introduction to Silicon Carbide Power Devices

Silicon carbide (SiC) power devices are semiconductor devices made of silicon carbide materials, mainly used in high-frequency, high-temperature, high-voltage and high-power electronic applications. Compared with traditional silicon (Si)-based power devices, silicon carbide power devices have higher......

Silicon Carbide Wafer Epitaxy Technology

Silicon Carbide generally uses the PVT method, with a temperature of more than 2000 degrees, a long processing cycle, and low output, so the cost of Silicon Carbide substrates is very high.

Difficulties in GaN preparation

As a third-generation semiconductor material, Gallium Nitride is often compared with Silicon Carbide. Gallium Nitride still demonstrates its superiority with its large bandgap, high breakdown voltage, high thermal conductivity, high saturated electron drift velocity and strong radiation resistance. ......

Introduction to Third-Generation Semiconductors: GaN and Related Epitaxial Technologies

GaN materials gained prominence following the awarding of the 2014 Nobel Prize in Physics for blue LEDs. Initially entering the public eye through fast-charging applications in consumer electronics, GaN-based power amplifiers and RF devices have also quietly emerged as critical components in 5G base......

Substrate vs. Epitaxy: Key Roles in Semiconductor Manufacturing

In the realms of semiconductor technology and microelectronics, the concepts of substrates and epitaxy hold significant importance. They play critical roles in the manufacturing process of semiconductor devices. This article will delve into the differences between semiconductor substrates and epita......
