This study introduces a single broadband on-wafer resistance calibration standard with excellent stability and a wide frequency range, fabricated with a 15-nm-thick gold resistor on an alumina substrate. The proposed standard demonstrates less than 2 K of heating and less than 0.2-dB difference in resistance response across the measured frequency band. This work marks a significant step towards establishing traceability of resistance standards over a wide frequency range.
We report a single broadband on-wafer resistance calibration standard fabricated with a 15-nm-thick gold resistor on an alumina substrate. Because the resistor film is much smaller than the skin depth at microwave frequencies, this proposed standard demonstrates excellent stability over both frequency and temperature when compared to traditional calibration resistors. A variety of resistors were fabricated, demonstrating resistances of 41-167 Omega in the frequency range of 10 MHz to 30 GHz. This resistance standard exhibits less than 2 K of heating when tested with 0 dBm of applied power and shows less than 0.2-dB difference in its resistance response across the measured frequency band. This work presents a significant step toward establishing the traceability of resistance standards over a wide frequency range.
