Abstract:
1. A method for producing an integrated circuit including a component, comprising: applying a first metallization layer at least locally onto a substrate, the first metallization layer having a bottom surface on the substrate, an opposing top surface, and side face; applying a second metallization layer onto the first metallization layer, the second metallization layer having a bottom surface on the top surface of the flrst metallization layer, an opposing top surface, and side faces; applying a hard mask directly onto the top surface of the second metallization layer and directly onto at least the side faces of the first and second metallization layers; opening the hard mask to expose a portion of the top surface of the second metallization layer and wet chemically etching the second metallization layer by using the hard mask, wherein remaining portions of the hard mask cover the side faces of the first and second metallization layers during the wet chemically etching.
