Abstract
A method of direct bonding comprising the following steps: supplying a first substrate and a second substrate, the first substrate being covered by a first hydrophilic surface and the second substrate being covered by a second hydrophilic surface, deposition of a specific molecule on the first hydrophilic surface and/or on the second hydrophilic surface, the specific molecule comprising a hydrophilic functional group and a basic functional group, separated by at least one atom, contacting the first hydrophilic surface with the second hydrophilic surface, whereby the two hydrophilic surfaces are bonded one with the other, and the first substrate and the second substrate are assembled, optionally, application of a bonding annealing heat treatment, preferably at a temperature less than or equal to 500° C.
