Abstract:
A device and method is described for producing an electrically conductive direct bond between a bonding side of a first substrate and a bonding side of a second substrate. A workspace is included that can be closed, gas-tight, against the environment and can be supplied with a vacuum. The workspace includes a) at least one plasma chamber for modifying at least one of the bonding sides and at least one bonding chamber for bonding the bonding sides, and/or b) at least one combined bonding/plasma chamber for modifying at least one of the bonding sides and for bonding the bonding sides.

Claim (Index 15):
A method for producing a direct bond between a bonding side of a first substrate and a bonding side of a second substrate in a workspace, the method comprising:\n modifying at least one of the bonding sides of the first and second substrates in one of a plasma chamber and a bonding/plasma chamber, the bonding side of the first substrate and the bonding side of the second substrate being composed of conductive regions and nonconductive regions, the modifying comprising:\n modifying an oxide layer by changing a stoichiometry of the oxide layer on the at least one of the bonding sides of the first and second substrates; \n introducing, into the one of the plasma chamber and the bonding/plasma chamber, one or more reducing gases selected from the group consisting of hydrogen, nitrogen oxide, carbon monoxide, and methane; and \n mixing the one or more reducing gases with one of more inert gases selected from the group consisting of xenon, argon, helium, nitrogen, and carbon dioxide; and \n subsequently bonding the bonding side of the first substrate with the bonding side of the second substrate in one of a bonding chamber corresponding with the plasma chamber or the bonding/plasma chamber, the subsequent bonding being enhanced by the modified oxide layer to form a hybrid bond between the conductive regions and the nonconductive regions of the first and second substrates.
