Abstract :
The test of MOSFET life is an important work in semiconductor manufacture. Many studies have been done on modeling the MOSFET life distribution for the reliability of integrated circuits. In this paper, a MOSFET life model is introduced by making use of threshold voltage drift property. A new statistical distribution, whose negative order moment estimator is just the maximum likelihood estimator, is deduced, and we call it NOME distribution. A new method of parameter estimate, F estimate of parameter, is proposed for complete sample test and truncated sample test. A kind of incomplete neural network is used to optimize the parameter in the model. Results show that neural network is a powerful tool for the analysis of MOSFET life model.
