The invention relates to a metallization (40) (and a semiconductor wafer (10) having corresponding metallization) and to a method for the production thereof that first of all can be produced by means of physical gas phase separation (dry separation) and secondly ensures sufficient adhesion of a lot bump. The method for producing a metallization (40) for at least one contact pad (20) according to the invention comprises the following process steps: applying at least one contact pad (20) to a substrate (10), applying a barrier layer (30) to the top side of the at least one contact pad (20) and applying a metallization (40) to the top side of the barrier layer (30), the barrier layer (30) and the metallization (40) being applied by means of physical separation and the metallization (40) being designed as a layer structure having two multiple alternating metallization layers (41, 42), wherein the first metallization layer (41) is made of nickel or an Ni alloy having a layer thickness of less than 500 nm and the second metallization layer (42) is made of a material that is different than nickel and is electrically conductive.
