The silicon carbide (SiC) industrial chain consists of several key stages: substrate material preparation, epitaxial layer growth, device manufacturing, and downstream applications.
SiC monocrystals are typically produced using the physical vapour transmission (PVT) method.
These crystals then serve as substrates for the chemical vapour deposition (CVD) process, which creates epitaxial layers.
These layers are subsequently used to manufacture various devices.
In the SiC device industry, the majority of the value is concentrated in the upstream substrate manufacturing stage due to its technical complexity.
ZMSH company offers SiC wafers in sizes 2inch, 4inch, 6inch, 8inch and 12inch.
Due to its exceptional hardness (SiC is the second hardest material globally) and stability under high temperatures and voltage,
SiC is extensively utilized across multiple industries.
*As well, we can customize if you have further requirements.
