On-Wafer Broadband Microwave Measurement of High impedance Devices-CPW Test Structures with Integrated Metallic Nano-resistances
Résumé
On-wafer microwave characterization and uncertainty evaluation of two-port coplanar waveguide (CPW) high impedance nanodevices devices are proposed. The test vehicles are built up with resistive metallic nano-films integrated in tapered CPW structures. Microwave conductance in the range 100-500µS associated to parallel capacitances in the order of hundreds aF are exemplary shown up to 20GHz. In addition, the uncertainty related to the post-calibration residual errors terms together with a sensitivity study to the technological process variability using FEM-based EM modelling are considered.
