    摘要: An improved bond ribbon design, said bond ribbon having a dual taper that functions to localize the bending along a predetermined distribution of the bond ribbon during the bonding of the bond ribbon to an associated contact of a semiconductor chip. Use of the dual-tapered bond ribbons during bonding provides a bonded bond ribbon having a form that is substantially s-shaped. The radii of curvature making out the curves of the s-shaped configuration can be predetermined and controlled by the length and taper of the individual tapered section. The improved bond ribbon further comprises an anchor pad, said anchor pad characterized by a large surface area that decreases the likelihood of delamination of it from a supporting dielectric structure. A multiplicity of these improved bond ribbons can be fabricated in an external connection component so as to facilitate the alignment and bonding process of multiple bond ribbons to corresponding contacts of the semiconductor chip and can be designed, configured or placed such that the corner contact of the semiconductor chip are accessible for bonding. With respect to the problems associated with accessing the corner contacts of a semiconductor chip when using the connection component, three approaches are offered as solutions.

    摘要: A connection component for a semiconductor chip includes a support structure having a top surface including a dielectric material and a bottom surface. The support structure includes a central portion, a peripheral portion and one or more gaps extending substantially between the central portion and the peripheral portion. A bus overlies the top surface of the support structure. The each bus has an outer edge which overlies the peripheral portion of the support structure and an inner edge which overlies the one or more gaps. The support structure also includes one or more electrically conductive leads having first ends secured to the central portion and second ends overlying the gaps and being secured to the inner edge of the bus. The second ends of the leads are displaceable relative to the bus in response to bonding forces being applied to the leads for engaging contacts on a semiconductor chip.

    摘要: Microelectronic assemblies such as semiconductor chip assemblies are encapsulated. During encapsulation, the terminals carried by a dielectric layer in each assembly, and the bottom surface of the semiconductor chip in each assembly are protected by covering layers. The covering layers confine the liquid encapsulant and prevent contamination of the terminals and chip bottom surfaces. The encapsulation process may be conducted by using a tilting fixture. The liquid encapsulant and the assemblies are placed into the fixture, the fixture is closed and evacuated, and the encapsulant is then poured onto the assemblies while maintaining the fixture under vacuum. The fixture is then pressurized and maintained under pressure during cure of the encapsulant.
