Abstract:
A shielded wiring structure of a semiconductor device, the structure comprising:a substrate;a first rectangular coaxial tube structure formed on said substrate, said first rectangular coaxial tube structure having a first inner conductor and a first conductive coaxial shield;a second rectangular coaxial tube structure formed on said substrate, said second rectangular coaxial tube structure having a second inner conductor and a second conductive coaxial shield, said second coaxial shield being discrete from said first coaxial shield;said first coaxial tube structure being located a predetermined distance away from said second coaxial tube structure;sidewalls of said first coaxial tube structure being elements of no coaxial tube structure other than said first coaxial tube structure;sidewalls of said second coaxial tube structure being sidewalls of no coaxial tube structure other than said second coaxial tube structure;wherein said first coaxial shield being electrically connected to said second coaxial shield;wherein top sides of said first and second rectangular coaxial tube structures are connected together by a third conductor having a planar surface; and wherein said third conductor being an element of no coaxial tube structure other than said first and second coaxial tube structureswherein a space is defined between said substrate, said third conductor and sidewalls of said first and second rectangular coaxial tube structures, the shielded tube structure further comprising a third insulator that fills in said space.
