| Abstract(in English) | In order to realize detailed analysis of measured contact resistance data, fitting of Weibull distribution function to contact resistance data is being tried. For that purpose, the original Weibull fitting software has been prepared, and applied to some sets of the measured data. When successful fitting results were obtained, the sum of two Weibull parameters, i.e., the location parameter Ro and the scale parameter Ra, became close to the average value of the contact resistance data. In addition, values of the scale parameter m showed certain differences for the data obtained with different load current values. These tendencies can be effectively utilized for analysis of contact resistance data. However, more revisions to the fitting algorithm are still required for realizing further study of contact resistance characteristics through the Weibull fitting analysis. Specifically, certain modifications are required in providing distribution of the measured contact resistances. The fitting procedures are also required to be improved in order to appropriately handle with a mixed mode distribution of data. |
