China Si Wafer Etching Manufacturers, Suppliers, Factory

In their newly released annual report, TSMC Chairman Deyin Liu and CEO Chieh-Jia Wei revealed the progress related to the 2nm process.

Every country is aware of the importance of chips and is now accelerating the construction of its own chip manufacturing supply chain ecosystem to prevent another chip shortage problem. But the advanced foundries without next-gen chip designers would be the same as “Fabs without Chips”.

Recently, the semiconductor industry has continued to pay increasing attention to Gallium Nitride (GaN) technology. Due to its excellent electronic properties, Gallium Nitride devices have important applications in many high-tech fields:

The third-generation wide bandgap semiconductor materials, such as Gallium Nitride (GaN) and Silicon Carbide (SiC), are renowned for their exceptional optoelectronic conversion and microwave signal transmission capabilities. These materials meet the demanding requirements of high-frequency, high-temperature, high-power, and radiation-resistant electronic devices. Therefore, they have vast application prospects in new-generation mobile communications, new energy vehicles, smart grids, and LED technologies. The comprehensive development of the third-generation semiconductor industry urgently requires breakthroughs in key core technologies, continual advancement in device design and innovation, and a resolution to import dependencies.

Electrostatic chucks (ESCs) have become indispensable in semiconductor manufacturing and flat panel display production, offering a damage-free, highly controllable method for holding and positioning delicate wafers and substrates during critical processing steps. This article delves into the intricacies of ESC technology, exploring its principles of operation, various adhesion mechanisms, and fundamental structural components.

Carbon-based materials such as graphite, carbon fibers, and carbon/carbon (C/C) composites are known for their high specific strength, high specific modulus, and excellent thermal properties, making them suitable for a wide range of high-temperature applications. These materials are widely utilized in aerospace, chemical engineering, and energy storage. However, their susceptibility to oxidation and corrosion in high-temperature environments, along with poor scratch resistance, restricts their further application.
