Abstract:
A single circuit board comprising a base member, an interconnect layer formed on a part of the base member, an electrically-floating conductive layer formed on a substantially remaining part of the base member and having an edge adjacent to an edge of the interconnect layer, and a dielectric layer covering a part of the interconnect layer and an entire surface of the electrically-floating conductive layer and filling a gap between the edge of the interconnect layer and the edge of the electrically-floating conductive layer, wherein the interconnect layer comprises a top interconnect layer on a top surface of the base member and a bottom interconnect layer on a bottom surface of the base member and the electrically-floating conductive layer includes a top electrically-floating conductive layer on the top surface of the base member and a bottom electrically floating conductive layer on the bottom surface of the base member.
