Abstract: A microelectronic package has a microelectronic element overlying or mounted to a first surface of a substrate and substantially rigid conductive posts projecting above the first surface or projecting above a second surface of the substrate remote therefrom. Conductive elements exposed at a surface of the substrate opposite the surface above which the conductive posts project are electrically interconnected with the microelectronic element. An encapsulant overlies at least a portion of the microelectronic element and the surface of the substrate above which the conductive posts project, the encapsulant having a recess or a plurality of openings each permitting at least one electrical connection to be made to at least one conductive post. At least some conductive posts are electrically insulated from one another and adapted to simultaneously carry different electric potentials. In particular embodiments, the openings in the encapsulant at least partially expose conductive masses joined to posts, fully expose top surfaces of posts and partially expose edge surfaces of posts, or may only partially expose top surfaces of posts.

Abstract: A method of making a microelectronic assembly can include molding a dielectric material around at least two conductive elements which project above a height of a substrate having a microelectronic element mounted thereon, so that remote surfaces of the conductive elements remain accessible and exposed within openings extending from an exterior surface of the molded dielectric material. The remote surfaces can be disposed at heights from said surface of said substrate which are lower or higher than a height of the exterior surface of the molded dielectric material from the substrate surface. The conductive elements can be arranged to simultaneously carry first and second different electric potentials: e.g., power, ground or signal potentials.

Abstract: A microelectronic assembly includes first and second stacked microelectronic elements, each having spaced apart traces extending along a front face and beyond at least a first edge thereof. An insulating region can contact the edges of each microelectronic element and at least portions of the traces of each microelectronic element extending beyond the respective first edges. The insulating region can define first and second side surfaces adjacent the first and second edges of the microelectronic elements. A plurality of spaced apart openings can extend along a side surface of the microelectronic assembly. Electrical conductors connected with respective traces can have portions disposed in respective openings and extending along the respective openings. The electrical conductors may extend to pads or solder balls overlying a face of one of the microelectronic elements.

Abstract: A structure including a first semiconductor chip with front and rear surfaces and a cavity in the rear surface. A second semiconductor chip is mounted within the cavity. The first chip may have vias extending from the cavity to the front surface and via conductors within these vias serving to connect the additional microelectronic element to the active elements of the first chip. The structure may have a volume comparable to that of the first chip alone and yet provide the functionality of a multi-chip assembly. A composite chip incorporating a body and a layer of semiconductor material mounted on a front surface of the body similarly may have a cavity extending into the body from the rear surface and may have an additional microelectronic element mounted in such cavity.

Abstract: A capacitor can include a substrate having a first surface, a second surface remote from the first surface, and a through opening extending between the first and second surfaces, first and second metal elements, and a capacitor dielectric layer separating and insulating the first and second metal elements from one another at least within the through opening. The first metal element can be exposed at the first surface and can extend into the through opening. The second metal element can be exposed at the second surface and can extend into the through opening. The first and second metal elements can be electrically connectable to first and second electric potentials. The capacitor dielectric layer can have an undulating shape.
