Filed: 2006-03-23
Abstract: <P>PROBLEM TO BE SOLVED: To correctly estimate the first dielectric breakdown life-time even when detectable dielectric breakdown is not necessarily the first dielectric breakdown in actual measurement.  <P>SOLUTION: A plurality of specimens belonging to each of specimen groups having different surface areas are subjected to Weibull plotting operation to find a dielectric breakdown life-time as a predetermined cumulative failure rate and Weibull slope, and to find an m value indicative of a dependency on the specimen surface area of each Weibull slope. A Weibull slope for the dielectric breakdown life-time and an m value until the first dielectric breakdown life-time in the evaluation target specimen are found, on the basis of a correlation between the Weipull slope and the m value until the first dielectric breakdown in the precalculated specimens. A surface area (a) is found when the surface area dependency of each Weipull slope causes the Weipull slope of the dielectric breakdown life-time of the measurement target specimen, to become the Weipull slope of the dielectric breakdown life-time until the first dielectric breakdown in the evaluation target specimen. A dielectric breakdown life-time in the surface area (a) is found by plotting the respective dielectric breakdown lives with respect to surface area.  <P>COPYRIGHT: (C)2008,JPO&INPIT
