  • What are epitaxial wafers used for?

    Epitaxial wafers have been used in the electronics industry for decades, but their importance has only increased as technology has advanced. In this article, we will explore what epitaxial wafers are and why they are such an essential component of modern electronics.

  • 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.

  • Differences between SiC crystals with different structures

    Silicon carbide (SiC) is a material that possesses exceptional thermal, physical and chemical stability, exhibiting properties that go beyond those of conventional materials. Its thermal conductivity is an astonishing 84W/(m·K), which is not only higher than copper but also three times that of silicon. This demonstrates its enormous potential for use in thermal management applications.

  • 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.

  • Crystal Orientation and Defects in Silicon Wafers

    The basic crystal unit cell of monocrystalline silicon is the zinc blende structure, in which each silicon atom bonds chemically with four neighboring silicon atoms. This structure is also found in monocrystalline carbon diamonds.

  • The unit in semiconductor: Angstrom

    As a unit of length, Angstrom (Å) is ubiquitous in integrated circuit manufacturing. From precise control of material thickness to miniaturization and optimization of device size, the understanding and application of Angstrom scale is the core to ensure the continuous development of semiconductor technology.
