Abstract:
1. A method for bonding of a first contact surface of a first substrate to a second contact surface of a second substrate comprised of the following steps: forming at least one reservoir in at least one reservoir formation layer on the first substrate and/or the second substrate, the reservoir comprised at least largely of an amorphous material, wherein the forming of the at least one reservoir as reservoir formation layer is by use of a tetraethoxysilane-oxide layer, at least partial filling of the reservoir/reservoirs with a first educt or a first group after the at least one reservoir is formed, forming or applying a reaction layer which contains a second educt or a second group to the reservoirs, after the at least one reservoir is filled, bringing the first contact surface in contact with the second contact surface for formation of a prebond connection, and forming a permanent bond between the first and second contact surface, at least partially strengthened by the reaction of the first educt or the first group with the second educt or the second group.
