Abstract
To manufacture a redistribution layer for an integrated circuit, a first insulating layer is formed on a conductive interconnection layer of a wafer. A conductive body is then formed in electrical contact with the interconnection layer. The conductive body is then covered with an insulating region having an aperture that exposes a surface of the conductive body. The surface of the conductive body and the insulating region are then covered with an insulating protection layer having a thickness less than 100 nm. This insulating protection layer is configured to provide a protection against oxidation and/or corrosion of the conductive body.
