Abstract:
1. A semiconductor packaging container comprising a bottomed cylindrical dielectric case including a dielectric substrate disposed on a dielectric base substrate that does not include ceramics, comprising: a first signal conductor and a first grounding conductor provided on a bottom surface of the dielectric case, the first signal conductor being capable of a direct connection with a signal terminal of a semiconductor chip, and the first grounding conductor forming a coplanar waveguide with the first signal conductor, and a second signal conductor provided at a position corresponding to the first signal conductor on a back of the bottom surface of the dielectric case, and a second grounding conductor provided at a position corresponding to the first grounding conductor on the back of the bottom surface of the dielectric case, wherein an electrical continuity is established between the first signal conductor and the second signal conductor through a via which passes through the bottom surface of the dielectric case and an electrical continuity is established between the first grounding conductor and the second grounding conductor through a via which passes through the bottom surface of the dielectric case, the vias passing directly from a top surface to the bottom surface thereof, and wherein the first grounding conductor is formed in such a manner that an edge opposing to and adjacent to the first signal conductor is shorter than an edge opposing to and not adjacent to the first signal conductor.
