摘要:
Embodiments of the present disclosure are directed towards techniques and configurations for dual surface finish package substrate assemblies. In one embodiment a method includes depositing a first lamination layer on a first side of a package substrate and a first surface finish on one or more electrical contacts disposed on a second side of the package substrate; removing the first lamination layer from the first side of the package substrate; depositing a second lamination layer on the second side of the package substrate and a second surface finish on the one or more electrical contacts disposed on the first side of the package substrate; and removing the second lamination layer from the second side of the package substrate. Other embodiments may be described and/or claimed.
摘要:
L'invention concerne un procédé d'assemblage de type Flip-Chip, entre un premier (1) et un deuxième (2) composants comportant chacun des plots de connexion (11, 21) sur une de leurs faces, dites faces d'assemblage, selon lequel on reporte les composants l'un sur l'autre par leurs faces d'assemblage de sorte à réaliser des interconnexions électriques entre les plots du premier et ceux du deuxième composant. Selon l'invention, on réalise une transformation de l'oxyde de cuivre en cuivre par recuit UV, très localement dans l'espacement entre composants au moins autour des zones au droit des plots de connexion. Le procédé selon l'invention peut être utilisé pour n'importe quel composant transparent aux UV, y compris pour des substrats en matière plastique tels que des substrats en PEN ou en PET. L'invention concerne également l'assemblage entre deux composants obtenu par le procédé.
摘要:
Semiconductor devices and device packages include at least one semiconductor die electrically coupled to a substrate through a plurality of conductive structures. The at least one semiconductor die may be a plurality of memory dice, and the substrate may be a logic die. An underfill material disposed between the at least one semiconductor die and the substrate may include a thermally conductive material. An electrically insulating material is disposed between the plurality of conductive structures and the underfill material. Methods of attaching a semiconductor die to a substrate, such as for forming semiconductor device packages, include covering or coating at least an outer side surface of conductive structures, electrically coupling the semiconductor die to the substrate with an electrically insulating material, and disposing a thermally conductive material between the semiconductor die and the substrate.
