Abstract (en)
[origin: WO8203294A1] A semiconductor device (10) including a metallurgically compatible unplated package. The package includes a plateless copper alloy die mount area (14) to which a semiconductor die (12) is attached. The semiconductor die (12) is metallized on its mounting surface (40) to provide electrical contact. A metallic solder (38) which is compatible with both the copper alloy and the die metallization joins the die (12) to the die mount area (14). The package further includes a plateless copper alloy lead portion (16) which is physically joined (42) to the die mount area (14). The top surface of the semiconductor die (12) is provided with a patterned metallization (24, 26) making electrical contact to select the portions of the die. Electrical contact is made between the top surface die metallization (24, 26) and the lead portion (16) of the package by ultrasonically bonded copper ribbon (28). The die (12) and interconnecting ribbon (28) is then enclosed by an epoxy encapsulant (18) or by a welded metal cover (58).
Abstract (fr)
Dispositif a semi-conducteur (10) comprenant un boitier non plaque metallurgiquement compatible. Le boitier comprend une zone de montage (2) de en alliage de cuivre sans placage (14) sur laquelle est fixee un de semi-conducteur (12). Le de semi-conducteur (12) est metallise sur sa surface de montage (40) pour assurer un contact electrique. Une soudure metallique (38) compatible aussi bien avec l'alliage de cuivre qu'avec la surface de metallisation du de relie le de (12) a la zone de montage de de (14). Le boitier comprend en outre une partie de conducteur en alliage de cuivre sans placage (16) reliee physiquement (42) a la zone de montage de de (14). La surface superieure du de semi-conducteur (12) est pourvue d'une couche de metallisation deposee selon un motif (24, 26) assurant le contact electrique avec des parties selectionnees du de. Le contact electrique entre la couche de metallisation de la surface superieure du de (24, 26) et la partie de conducteur (16) du boitier est realisee au moyen d'un ruban (28) de cuivre soude aux ultrasons. Le de (12) et le ruban d'interconnection (28) sont ensuite proteges par un element de scellement epoxyde (18) ou par un couvercle metallique soude (58).
