China Silicon Carbide Edge Ring Manufacturers, Suppliers, Factory

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”.

Silicon carbide (SiC) has important applications in areas such as power electronics, high-frequency RF devices, and sensors for high-temperature-resistant environments due to its excellent physicochemical properties. However, the slicing operation during SiC wafer processing introduces damages on the surface, which, if left untreated, can expand during the subsequent epitaxial growth process and form epitaxial defects, thus affecting the yield of the device.

The growth of GaN epitaxy on GaN substrate presents a unique challenge, despite the material’s superior properties when compared to silicon. GaN epitaxy offers significant advantages in terms of band gap width, thermal conductivity, and breakdown electric field over silicon-based materials. This makes the adoption of GaN as the backbone for the third generation of semiconductors, which provide enhanced cooling, lower conduction loss, and improved performance under high temperatures and frequencies, a promising and crucial advancement for the photonic and micro-electronic industries.

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 a wide-bandgap (WBG) semiconductor material, SiC's wider energy difference gives it higher thermal and electronic properties compared to traditional Si. This feature enables power devices to operate at higher temperatures, frequencies and voltages.
