This is the 248th original article by a lifelong learner. What do the three generations of semiconductor materials refer to? A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator at room temperature. Common semiconductors include silicon, germanium, and compound semiconductors such as gallium arsenide, indium phosphide, gallium … Read more
Since the 21st century, third-generation semiconductor materials represented by Gallium Nitride (GaN), Silicon Carbide (SiC), and Zinc Oxide (ZnO) have begun to emerge.However, with the continuous increase in demand for high-load computing power from 6G communication, AI smart chips, and CPUs/GPUs, complex and expensive data center cooling systems are required to maintain performance and prevent … Read more
GaN has been regarded as a “fast charging star” over the past decade, starting from mobile phones and laptop power supplies, gradually achieving product evolution in terms of high frequency, high efficiency, and miniaturization. However, what STMicroelectronics (hereafter referred to as ST) is doing this time is distinctly different — it has “liberated” GaN from … Read more
This chapter introduces some technologies that design Gallium Nitride (GaN) for power amplifiers (PAs) and other applications, describing how GaN is widely used in RF (Radio Frequency) front ends. We also explore how technology leaders provide discrete, monolithic microwave integrated circuits (MMICs), and highly integrated modules to accommodate multiple application areas. Additionally, we explain the … Read more
Introduction Since 2020, Dongke Semiconductor has been continuously focusing on the field of integrated chips, successively launching the industry’s first fully integrated GaN asymmetric half-bridge product, the only fully integrated high-voltage active clamp flyback (ACF) chip, integrated quasi-resonant (QR) flyback chip, and a series of highly integrated synchronous rectification integrated chips. These products have successfully … Read more
To address the issue of node overload and even failure due to resource constraints in the Industrial Internet of Things (IIoT) edge computing environment, the author proposes a fault tolerance method based on edge intelligence called SGAT-GAN (Sparse Graph Attention-based Generative Adversarial Network). This method integrates a fault prediction mechanism and utilizes Fault Embedding Encoder … Read more
In applications such as robotics, drones, and low-voltage high-power servo drives, high-efficiency and high-power density motor drive solutions have always been the core demand in system design. As the demand for low-voltage high power continues to rise, traditional silicon-based devices are gradually approaching their limits in terms of switching frequency, conduction loss, and temperature rise, … Read more
The first generation of semiconductors is led by SMIC. It is the first choice for entering the semiconductor industry, often referred to as the “Huangpu Military Academy”. Following that are Wuhan Xinxin, Yangtze Memory Technologies, Changxin Technology, Qingdao Xinen, Silicon Motion, Shaoxing, UMC, and others. For the third generation of semiconductors, the most comprehensive and … Read more
The global leader in GaN power semiconductor market share, from NASA scientists to leaders in China’s third-generation semiconductor sector, Dr. Luo Weiwei has led Innosilicon on a hardcore tech entrepreneurial path. On December 30, 2024, Innosilicon successfully listed on the Hong Kong Stock Exchange, becoming the first stock in the “third-generation semiconductor” category. Founded in … Read more
