In a semiconductor device for treating signals of frequency not less than 800 MHz, a minimum thickness of an electrically conductive wire connecting a semiconductor electric circuit in the semiconductor device to an electric member other than the semiconductor device is determined along the following formula: <math-cwu id="MATH-US-00001"> <number>1</number> <math> <mrow> <mrow> <mn>2</mn> <mo>*</mo> <msqrt> <mfrac> <mn>2</mn> <mrow> <mi>ω</mi> <mo>it</mo> <mstyle> <mtext> </mtext> </mstyle> <mo>it</mo> <mi>mu</mi> <mo>it</mo> <mstyle> <mtext> </mtext> </mstyle> <mo>it</mo> <mi>κ</mi> </mrow> </mfrac> </msqrt> </mrow> <mo><</mo> <mi>h</mi> </mrow> </math> <mathematica-file id="MATHEMATICA-00001" file="US20030071284A1-20030417-M00001.NB"/> <image id="EMI-M00001" wi="216.027" he="23.04855" file="US20030071284A1-20030417-M00001.TIF" imf="TIFF" ti="MF"/> </math-cwu> when h is the minimum thickness of the electrically conductive wire, kappa is an electrical conductivity of the electrically conductive wire, mu is a magnetic permeability of the electrically conductive wire, omega is an angular frequency of the signals transmitted through the electrically conductive wire.
