Oxide-to-oxide fusion bonding has been the standard process since its use for more than a decade for the manufacturing of layered substrates or engineered substrates, such as silicon-on-insulator (SOI) wafers. Oxide layers at the interface enable this type of bonding, in turn leading to a non-conductive interface between both bonded substrates.
