Abstract
The invention relates to a method for connecting two joining surfaces, particularly in the field of semiconductors, wherein at least one joining surface is produced by depositing a layer comprising 20 to 40% gold and 80 to 60% silver onto a substrate and selectively removing the silver from the deposited layer in order to produce a nanoporous gold layer as a joining surface. The joining surface with the nanoporous gold layer and an additional joining surface are disposed one above the other and pressed together.
