讨论了斜坡电流测试的相关参数如电流斜坡速率、步长及电流倍增速率对测试结果击穿电荷具有的严重影响.指出斜坡电流测试中各个参数的设定、影响及其相关性,使斜坡电流测试的结果具有可比较性.同时,讨论了由于斜坡电流测试本身的特性,击穿电荷具有非连续性,针对击穿电荷的非连续性,提供了一种统计上的数据处理方法,并且根据工程上不同的定性比较结果提供了不同的统计比较方法,可以对非连续的斜坡电流测试结果进行定量的统计比较.在产品验证或生产线出现异常时,能够进行统计上的比较,给出定量的结果.据此能对生产线的稳定性或异常事件对产品的影响给出明确的结论,为受影响的产品的处置提供定量的数据支持.这是首次对斜坡电流测试数据的统计定量分析.

The impacts of ramp rates,step times,and the F-factor to the charge breakdown (Qba) in Jramp tests are studied and also comment the Jramp parameter settings and their mutual impacts so the Jramp test results can be compared.For the non-continuity characteristic of Jramp tests,a statistical method using confidence limits is proposed to compare Jramp test data quantitatively.This proposed solution realizes the possibility to evaluate Qbd performance with sound statistical meaning and quantificational indices,which are especially important at qualifications or when abnormalities are found during mass production.It can greatly help to make obvious conclusion regarding the process stability se as to take effective actions on the nonconformance and on the lot disposition.This statistical method is the first quantitative data comparison approach for the Jramp data.
