Methods for Wafer Bonding, and for Nucleating Bonding Nanophases

Substrates may be bonded according to a method comprising contacting a first bonding surface of a first substrate with a second bonding surface of a second substrate to form an assembly, and compressing the assembly in the presence of an oxidizing atmosphere under suitable conditions to form a bondi...

Zusammenfassung:Substrates may be bonded according to a method comprising contacting a first bonding surface of a first substrate with a second bonding surface of a second substrate to form an assembly, and compressing the assembly in the presence of an oxidizing atmosphere under suitable conditions to form a bonding layer between the first and second surfaces, wherein the first bonding surface comprises a polarized surface layer; the second bonding surface comprises a hydrophilic surface layer; the first and second bonding surfaces are different.
