  • Why choose SiC-coated graphite susceptors?

    Graphite susceptor is one of the essential parts in the MOCVD equipment, is the carrier and the heater of the wafer substrate. Its properties of thermal stability and thermal uniformity play a decisive role in the quality of wafer epitaxial growth, which directly determines the uniformity and purity of the layer materials, in a result its quality directly affects the preparation of epitaxy.

  • Why choose liquid phase epitaxy method?

    Compared with the PVT method, the liquid phase method for growing SiC has the following advantages:

  • Introducing Physical Vapor Transport (PVT) 

    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.

  • Method for preparing SiC powder

    Silicon carbide (SiC) is an inorganic substance. The amount of naturally occurring silicon carbide is very small. It is a rare mineral and is called moissanite. Silicon carbide used in industrial production is mostly artificially synthesized.

  • Challenges of Ion Implantation Technology in SiC and GaN Power Devices

    Wide bandgap (WBG) semiconductors such as Silicon Carbide (SiC) and Gallium Nitride (GaN) are expected to play an increasingly important role in power electronic devices. They offer several advantages over traditional Silicon (Si) devices, including higher efficiency, power density, and switching frequency. Ion implantation is the primary method for achieving selective doping in Si devices. However, there are some challenges when applying it to wide bandgap devices. In this article, we will focus on some of these challenges and summarize their potential applications in GaN power devices.
