Substrate Cutting and Grinding Process

SiC substrate material is the core of SiC chip. The production process of the substrate is: after obtaining the SiC crystal ingot through single crystal growth; then preparing the SiC substrate requires smoothing, rounding, cutting, grinding (thinning); mechanical polishing, chemical mechanical poli......

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 silic......

What is a TaC coating on graphite?

In the rapidly evolving field of semiconductor manufacturing, even the smallest improvements can make a big difference when it comes to achieving optimal performance, durability, and efficiency.
