Abstract
A method for bonding of a first, at least partially metallic contact surface of a first substrate to a second, at least partially metallic contact surface of a second substrate, with the following steps, especially the following progression: application of a sacrificial layer which is at least partially, especially predominantly soluble in the material of at least one of the contact surfaces to at least one of the contact surfaces, bonding of the contact surfaces with at least partial solution of the sacrificial layer in at least one of the contact surfaces.
