摘要： A microelectronic assembly includes an interconnection element, a conductive plane, a microelectronic device, a plurality of traces, and first and second bond elements. The interconnection element includes a dielectric element, a plurality of element contacts, and at least one reference contact thereon. The microelectronic device includes a front surface with device contacts exposed thereat. The conductive plane overlies a portion of the front surface of the microelectronic device. Traces overlying a surface of the conductive plane are insulated therefrom and electrically connected with the element contacts. The traces also have substantial portions spaced a first height above and extending at least generally parallel to the conductive plane, such that a desired impedance is achieved for the traces. First bond element electrically connects the at least one conductive plane with the at least one reference contact. Second bond elements electrically connect device contacts with the traces.

摘要： A microelectronic assembly may include a microelectronic element having a plurality of element contacts at a face thereof, and a compliant dielectric element having a Young's modulus of less than about two gigapascal (GPa) and substrate contacts at a first surface joined to the element contacts. The substrate contacts may be electrically connected with terminals at a second surface of the compliant dielectric element that opposes the first surface, through conductive vias in the compliant dielectric element. A rigid underfill may be between the face of the microelectronic element and the first surface of the compliant dielectric element. The terminals may be usable for bonding the microelectronic assembly to corresponding contacts of a component external to the microelectronic assembly.

摘要： A microelectronic assembly includes a semiconductor chip having chip contacts exposed at a first face and a substrate juxtaposed with a face of the chip. A conductive bond element can electrically connect a first chip contact with a first substrate contact of the substrate, and a second conductive bond element can electrically connect the first chip contact with a second substrate contact. The first bond element can have a first end metallurgically joined to the first chip contact and a second end metallurgically joined to the first substrate contact. A first end of the second bond element can be metallurgically joined to the first bond element. The second bond element may or may not touch the first chip contact or the substrate contact. A third bond element can be joined to ends of first and second bond elements which are joined to substrate contacts or to chip contacts. In one embodiment, a bond element can have a looped connection, having first and second ends joined at a first contact and a middle portion joined to a second contact.
