Last, Nano Indenter XP was used to measure the mechanical properties of the fabricated probe structures, the results show that the spring constants of cantilever type and simply supported beam type probe structures were 2556 Nm-1 and 26280 Nm-1 respectively, which were close to the designed values of 2838 Nm-1 and 23935 Nm-1 with the error of 9.94% and 8.92%. DC probes and HP 4194A Impedance/Gain-phase Analyzer were adopted to measure the electrical properties of the simply supported beam probe card. The contact resistance from the probe tip to the end of stripline was 0.6Ω. In the frequency range of 5 to 40 MHz, the characterized impedance between two probes was larger than 20 kΩ, and the capacitance was from 0.17 pF to 0.27 pF.

It is shown that the Nix-Gao relation between the microindentation hardness and indentation depth holds for all the six indenter angles. The effect of friction is negligible for relatively flat indenters (e.g., Berkovich indenter), but may be significant for sharp indenters (e.g., cubic indenter).
