SOI Wafer Applications

In the case where silicon on insulator wafers with extremely top thin silicon layers that have a thickness of fewer than 1.5 micrometers are needed, the smart cut approach has to be used. This is because this method produces high-quality SOI substrates by combining direct wafer bonding and layer transfer by ion implantation (I. Radu, 2021).
