A semiconductor component package utilizing a cavity substrate is disclosed. The package effectively connects terminals of the semiconductor component to substrate pads on the semiconductor surface within the cavity using a solder preform. The solder preform is configured to fit the semiconductor component within a preform cavity. The solder preform is positioned over the pads on the cavity substrate and reflowed, forming interconnections between the semiconductor component terminals and the substrate pads. In addition, solder fillets are formed surrounding the semiconductor terminal to advantageously increase the strength of the interconnections, providing a more reliable semiconductor component package.

A system that includes improved integrated circuit interconnects integrated with interconnect capacitors that reduce noise and improve signal quality is disclosed. The system comprises a first circuit board layer including a contact region of a conductor trace. The system further comprises a second layer including an interconnect capacitor, wherein the interconnect capacitor comprises a first side coupled over at least a portion of the contact region of the first circuit board layer to form a contact pad on a second side of the interconnect capacitor configured to interface with an integrated circuit chip.

Molded device packages which allow electrical contacts to coupled to a first surface of a circuit substrate such as a printed circuit board while allowing the opposite surface to remain exposed for other purposes such as bonding thermal structures such as heatsinks include electrically-conductive pillars which are bonded to the first surface of the substrate and encapsulated in molding material. The molding material can one or more cavities over disposed over the first surface of the substrate which can be evacuated or gas-filled. The electrically-conductive pillars protrude from connected manifold and are joined to each other by a frame portion of the manifold. The manifold is patterned with a masking material that protects the pillars from being etched during a selective etching process which removes the frame portion of the manifold to separate the electrically-conductive pillars from each other.

A circuit board structure includes a build-up structure, a graphene layer disposed on the build-up structure, and at least one conductive pillar disposed on the graphene layer, the graphene layer includes an oxidized area not covered by the at least one conductive pillar and a non-oxidized area covered by the at least one conductive pillar, and the at least one conductive pillar is electrically connected to the build-up structure via the non-oxidized area.
