This suppression of wafer bow stems from the almost complete release of strain in the 3C-SiC epilayers, and minimisation of the thermal mismatch between the epilayer and the silicon substrate. If it is warranted, further reduction in wafer bow may be accomplished with standard compensation techniques used in the silicon industry, such as selective epitaxy or growing on thicker substrates.
