Title (EN) UNDER-BUMP METALLIZATION STRUCTURE COMPRISING SUPERCONDUCTING MATERIAL
(FR) STRUCTURE DE MÉTALLISATION SOUS BOSSE COMPRENANT UN MATÉRIAU SUPRACONDUCTEUR
Abstract:
(EN) An under-bump-metallization (UBM) structure includes a first region and a second region. The first and second regions are laterally positioned inthe UBM structure. The first region includes a superconducting material. A substrate opposes the UBM structure. A superconducting solder material joins the first region to the substrate and the second region to the substrate.
(FR) La présente invention concerne une structure de métallisation sous bosse (UBM pour Under-Bump-Metallization) qui comprend une première et une seconde région. Les première et seconde régions sont positionnées latéralement dans la structure de métallisation UBM. La première région comprend un matériau supraconducteur. Un substrat fait face à la structure de métallisation UBM. Un matériau de soudure supraconducteur relie la première région au substrat et la seconde région au substrat.
