Abstract :
Coplanar strips that are representative of on-chip high-speed digital circuit interconnects have been fabricated on GaAs and characterized up to 18 GHz. Strip widths of 4, 6, and 8 mu m with strip spacings of 4 and 8 mu m and conductor thicknesses of 2500 AA and 5000 AA were used in the experiments. Line parameters such as resistance, capacitance, inductance per unit length, and propagation constant were extracted from these measurements. Measurement results confirm the quasi-TEM (transverse electromagnetic) properties of such interconnects.<>
