Claim 0:
1. A method of manufacturing a bonded substrate stack, the method comprising:
providing a first substrate having a first hybrid interface layer, the first hybrid interface layer comprising a first insulator and a first metal;
providing a second substrate having a second hybrid interface layer, the second hybrid interface layer comprising a second insulator and a second metal;
surface-activating the first hybrid interface layer and the second hybrid interface layer to generate dangling bonds on the first hybrid interface layer and on the second hybrid interface layer; and
bringing the surface-activated first hybrid interface layer and the surface-activated second hybrid interface layer into contact, such that the dangling bonds of the first hybrid interface layer and the dangling bonds of the second hybrid interface layer bond together to form first insulator to second insulator bonds and/or first metal to second metal bonds.
