Title
(EN) INTERCONNECTS THROUGH DIELECTRIC VIAS
(FR) INTERCONNEXIONS À TRAVERS DES TROUS D'INTERCONNEXION DIÉLECTRIQUE
Abstract
(EN) A dielectric layer includes a reflow via. The reflow via is formed by reflow of the dielectric layer. An interconnect is in contact through the reflow via.
(FR) L'invention concerne une couche diélectrique qui comprend un courant de retour de trous d'interconnexion. Le courant de retour du trou d'interconnexion est formé par l'intermédiaire du courant de retour de la couche diélectrique. Une interconnexion est en contact à travers le courant de retour du trou d'interconnexion.
