Abstract
A method for forming a transmission line arrangement providing control of signal losses through the use of conductor cross-sectional surface area-increasing and skin effect-considered bulbous additions to the rectangular conductor cross-sectional shape frequently used in semiconductor device transmission line conductors. The achieved transmission line is especially suited for use in radio frequency integrated circuit assemblies where it also includes a backplane member, encounters signals in the microwave and millimeter wavelength range and involves conductor dimensions measured in micrometers. Control of transmission line characteristic impedance at, for example, 50 ohms is disclosed as is use of semiconductor device-compatible materials and loss comparisons data.
