China SiC spare part 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.

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.

AlN, as third-generation semiconductor material, is not only an important blue light and ultraviolet light material, but also an important packaging, dielectric isolation and insulation material for electronic devices and integrated circuits, especially suitable for high-temperature and high-power devices. In addition, AlN and GaN have a good thermal match and chemical compatibility, AlN used as GaN epitaxial substrate, can significantly reduce the defect density in GaN devices, improve device performance.

Etching is an essential process in semiconductor manufacturing. This process can be categorized into two types: dry etching and wet etching. Each technique has its own advantages and limitations, making it crucial to understand the differences between them. So, how do you choose the best etching method? What are the pros and cons of dry etching and wet etching?

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”.
