摘要:
A method for manufacturing and for testing an integrated circuit, including the steps of forming, on the upper portion of the integrated circuit, a passivation layer including openings at the level of metal tracks of the last interconnect stack of the integrated circuit; forming, in the openings, first pads connected to second pads formed on the passivation layer by conductive track sections, the first pads being intended for the connection of the integrated circuit; testing the integrated circuit by bringing test tips in contact with the second pads; and eliminating at least a portion of at least one of the conductive track sections.
