4.1 Substrates and pseudo-substrates

The need to produce SiC-based components on an industrial scale very quickly led potential users to join forces to produce "electronic" quality substrates. Today, in specialized laboratories, ingots can reach 2 kg , while the standard wafer size on the market is 75 mm and 100 mm in diameter (i.e. 3 in and 4 in). Finally, since 2010, Cree has been announcing the forthcoming launch of 150 mm (~ 6 in) substrates with an average macrodefect density (microtubes...
