Abstract:
1. An integrated circuit comprising one or several metallization levels, metal conductive strips and a metal contact pad being formed on a last metallization level, wherein the metal contact pad has a first length, a first width, and a first thickness, the first thickness being the distance from a bottom of the metal contact pad to a top of the metal contact pad, wherein the first length and the first width are greater than the first thickness, the last level being covered with a passivation layer in which is formed an opening above the contact pad, wherein the metal conductive strips have a second thickness along a same direction as the first thickness, wherein the first thickness of the metal contact pad, over an entire area of the metal contact pad not covered by the passivation layer, is smaller than the second thickness of said conductive strips prior to application of an external contact to the metal contact pad, wherein the entire top of the metal contact pad within the opening has a substantially flat surface extending substantially throughout the entire opening.
