Abstract:
A flip-chip assembly, comprising:a carrier substrate bearing conductors thereon including a ground conductor and a power conductor; a semiconductor die including an active surface bearing internal circuitry and an opposing backside surface, the active surface exhibiting a power contact and a ground contact; a plurality of external communication traces over the active surface, wherein each of the external communication traces is adapted for directing signals between the internal circuitry of the semiconductor die and a site on the active surface for connection with external components; a plurality of spaced-apart bond pads in electrical contact with at least some of the external communication traces; electrically conductive bumps on at least some of the plurality of spaced-apart bond pads; at least one capacitor coupon positioned substantially parallel to and adjacent the opposing backside surface of the semiconductor die, the at least one capacitor coupon having a ground contact and a power contact; and electrical connections between the power and ground contacts of the semiconductor die and the at least one capacitor coupon and between the ground conductor and power conductor of the carrier substrate and the at least one capacitor coupon.
