Refining SiC epi-growth for high-volume production - …

SiC epilayers are formed by introducing silicon and carbon precursors into a chaer containing substrates heated to around 1600 C. The precursors are decomposed and atoms of silicon and carbon impinge on the substrates, migrate and bind together to form SiC epilayers (see Figure 1, which highlights the main chemical reactions occur during the epitaxial growth, as well as the design of the HWCVD tool).
