摘要 |
The invention concerns the forming of a microelectronic device comprising a substrate containing at least one conductive pad, the said pad being provided with a bottom surface resting on the substrate and an upper surface opposite said bottom surface, the said upper surface of said pad having a stack applied thereto formed of a conductive layer and a protective dielectric layer comprising an opening called first opening facing said pad and exposing the said conductive layer, at least one insulating block (120a, 120b) being arranged on a peripheral region of said upper surface of said pad, the said insulating block (120a, 120b) having a cross-section forming a closed contour and comprising an opening called second opening, a conductive pillar (130a, 130b) being located in the centre of said contour in the said second opening. |
