Patent ID: 7411279

Claim:
A circuit structure comprising: a first dielectric layer having first and second surfaces and an at least partially hollow elongate channel having opposite walls extending at least partially between the first and second surfaces; a first conductive layer disposed on at least a portion of the first surface; a first conductor disposed on the second surface of the first dielectric layer and having opposite conductor sides and a conductor end facing the substrate component and extending between the conductor sides, the channel being spaced from the first conductor and including at least an elongate first channel portion and an elongate second channel portion, the first and second channel portions extending in alignment lengthwise and transverse to the conductor sides, spaced from and adjacent to the conductor end and proximate to the substrate component, the first channel portion having opposite first-channel-portion sides and a first channel-portion end extending between the first-channel-portion sides, and the second channel portion having opposite second-channel-portion sides and a second channel-portion end extending between the second-channel-portion sides and adjacent to and facing the first channel-portion end, the first and second channel-portion ends being spaced apart with a portion of the first dielectric layer extending between the first and second channel-portion ends; a second conductive layer lining at least the walls of the first elongate channel portion, the second conductive layer being insufficient to fill the first and second elongate channel portions; a first interconnect; and a substrate component mounted on the second surface spaced from the conductor end, and having a terminal, the first interconnect extending between the conductor end and the substrate component terminal; at least a first portion of the substrate component being mounted on the portion of the dielectric layer and being predominantly on one side of both of the first and second channel portions.
