L'invention concerne un procédé permettant de fabriquer des composants électroniques incorporant un micro-composant inductif, disposé au dessus d'un substrat. Un tel composant comporte: - une succession de couches (10, 10a) de matériau à faible permittivité relative séparées par des couches de masque dur (12), la première couche de matériau à faible permittivité relative, reposant sur la face supérieure du substrat (1); - un ensemble de spires métalliques (30-31), définies au-dessus de la succession de couches (10, 10a) de matériau à faible permittivité relative; - une couche (15) barrière à la diffusion du cuivre, interposée entre les spires métalliques (30-31) et la couche sous-jacente de matériau à faible permittivité relative.
