Abstract

La présente invention concerne un appareil permettant d'interconnecter verticalement des piles de segments en silicium. Chaque segment comprend une pluralité de dés adjacents sur une tranche de semiconducteur. La pluralité de dés sur un segment sont interconnectés sur le segment en utilisant une ou plusieurs couches d'interconnexions métalliques s'étendant sur les quatre coins du segment, de manière à former des plots de connexion de bord pour les points de connexion électriques externes. Après interconnexion des dés, le découpage de chaque segment s'effectue depuis l'envers de la tranche au moyen d'une coupure en biseau, afin d'obtenir quatre parois de bords inclinées vers l'intérieur sur chacun des segments. Après découpage des segments de la tranche, ils sont disposés les uns sur les autres de façon à former une pile. Les segments verticalement adjacents de la pile sont électriquement connectés en appliquant une époxy électroconductrice sur un ou plusieurs côtés de la pile. Les parois de bords inclinées vers l'intérieur de chaque segment de la pile forment un évidement qui permet à l'époxy d'accéder au plots de connexion de bord et aux circuits latéraux sur chaque segment, une fois les segments empilés. On applique un revêtement diélectrique sur les dés pour réaliser un revêtement conforme permettant de protéger et d'isoler le dés, et on utilise un laser pour pratiquer l'ablation de la surface au-dessus des plots de connexion, de manière à retirer le revêtement diélectrique et former ainsi des connexions électriques pour les plots de connexion.
