Plasma Enhanced Chemical Vapor Deposition (PECVD) is a widely used technology in chip manufacturing. It utilizes the kinetic energy of electrons within plasma to activate chemical reactions in the gas phase, thereby achieving thin-film deposition.

Single crystal silicon and polycrystalline silicon each have their own unique advantages and applicable scenarios. Single crystal silicon is suitable for high-performance electronic products and microelectronics due to its excellent electrical and mechanical properties. Polycrystalline silicon, on the other hand, dominates the field of solar cells due to its low cost and good photoelectric conversion efficiency.

A diffusion furnace is a specialized piece of equipment used to introduce impurities into semiconductor wafers in a controlled manner. These impurities, called dopants, change the electrical properties of semiconductors, allowing different types of electronic components to be made. This controlled diffusion process is critical to the production of transistors, diodes and integrated circuits.

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.

SiC's own characteristics determine its single crystal growth is more difficult. Due to the absence of Si:C=1:1 liquid phase at atmospheric pressure, the more mature growth process adopted by the mainstream of the semiconductor industry can not be used to grow the more mature growth method-straight pulling method, the descending crucible method and other methods for growth. After theoretical calculations, only when the pressure is greater than 105 atm and the temperature is higher than 3200 ℃, can we get the stoichiometric ratio of Si:C = 1:1 solution. pvt method is currently one of the more mainstream methods.
