    Silicon on Insulator an overview | ScienceDirect Topics

    ·

    Silicon on insulator (SOI) wafers are manufactured by bonding one Si wafer to the other by activating the surface of both wafers and then placing them together so that a strong bond occurs first through the van der Waals attraction and then by forming a covalent bond [59].Activation of the superclean Si surface is the key to accomplish this bonding, typically by a remote plasma process....
