Inspection, Metrology Challenges Grow For SiC

“Silicon carbide is the third hardest compound material on earth with a material hardness of 9.5 on the Mohs scale,” said Meng Lee, director of product marketing at Veeco. “Due to the high hardness and brittleness of SiC, manufacturers are facing cycle time, cost and dicing performance challenges.”


Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.
