Abstract
Abstract A substrate or a ceramic package for packaging semiconductor chips, which comprises an insulating layer having a signal line on one surface of said insulating layer and a power line or ground line corresponding to said signal line on the other surface of said insulating layer. A well-controlled constant high frequency characteristics, and particularly, characteristic impedance, can be obtained on the signal line without being influenced by the power line or ground line.
