A SiC boat, short for silicon carbide boat, is a high-temperature-resistant accessory used in furnace tubes to carry wafers during high-temperature processing. Due to the outstanding properties of silicon carbide such as resistance to high temperatures, chemical corrosion, and excellent thermal stability, SiC boats are extensively utilized in various thermal treatment processes including diffusion, oxidation, Chemical Vapor Deposition (CVD), and annealing.

This article delves into the usage and future trajectory of silicon carbide (SiC) boats in relation to quartz boats within the semiconductor industry, specifically focusing on their applications in solar cell manufacturing.

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:

Japan recently restricted exports of 23 types of semiconductor manufacturing equipment. The announcement has sent ripples across the industry, as the move is expected to have a significant impact on global supply chains for semiconductor manufacturing.

Recently, Infineon Technologies announced the successful development of the world’s first 300mm power Gallium Nitride (GaN) wafer technology.

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.
