In semiconductor manufacturing, the precision and stability of the etching process are paramount. One critical factor in achieving high-quality etching is ensuring that wafers are perfectly flat on the tray during the process. Any deviation can lead to uneven ion bombardment, causing undesirable angles and variations in etching rates. To address these challenges, engineers have developed Electrostatic Chucks (ESCs), which have significantly improved etching quality and stability. This article delves into the design and functionality of ESCs, focusing on one key aspect: the electrostatic principles behind wafer adhesion.

​As the world searches for new opportunities in the semiconductor field, Gallium Nitride (GaN) continues to stand out as a potential candidate for future power and RF applications. However, despite its numerous benefits, GaN faces a significant challenge: the absence of P-type products. Why is GaN hailed as the next major semiconductor material, why is the lack of P-type GaN devices a critical drawback, and what does this mean for future designs?

In modern electronics, optoelectronics, microelectronics, and information technology fields, semiconductor substrates and epitaxial technologies are indispensable. They provide a solid foundation for manufacturing high-performance, high-reliability semiconductor devices. As technology continues to advance, semiconductor substrates and epitaxial technologies will also progress, bringing new breakthroughs and developments to the future of the semiconductor industry.
