ABSTRACT:
A packaged semiconductor device has a package, a semiconductor IC chip disposed in a space formed in the package, a strip conductor buried at a first level in the package for carrying a signal to be coupled to the IC chip, a first reference potential conductor buried at a second level in the package for providing a reference potential for the IC chip and a second reference potential conductor buried at the first level in the package for shielding the strip conductor. A connection conductor such as a bonding wire is provided across the second reference potential conductor for connecting the IC chip with one of the ends of the strip conductor. A dielectric material is provided between the connection conductor and the second reference potential conductor to provide the connection conductor with a characteristic impedance matched with an impedance of a source of the signal the connection conductor carries. The package may have an interconnecting conductor extending to electrically connect the first and second reference potential conductors.
