Abstract
In a superhigh speed device driven by GHz band frequencies, a semiconductor integrated circuit device is provided, in which an adjusting impedance is arranged in the inside of a high frequency package accommodating a semiconductor chip to compensate for the mismatching between the characteristic impedance of the package wiring and the terminal impedance of the signal transmission line in the package in order to adjust the input impedance to the characteristic impedance of the signal transmission line.
