Abstract
The reliability of semiconductor devices is a key indicator to measure the reliability of electronic devices. In view of the difficulties in modeling, low prediction accuracy and long prediction period faced by traditional reliability prediction methods of semiconductor devices, a deep learning based reliability prediction method of semiconductor devices is proposed in this paper. Besides, the accelerated degradation test data set of bipolar transistors under constant stress of temperature and humidity is analyzed, and the failure sensitive parameter Icbo of transistors is determined. The Data Fitting, LSTM, GRU and GRU-LSTM models are used to predict the trend of Icbo degradation of three transistors which are randomly selected from data set. The prediction results of device storage life using data fitting method and GRU-LSTM model are compared, and it is found that the overall distribution of device storage life predicted by the two methods is similar, but the prediction accuracy of GRU-LSTM model is higher and more suitable to the actual situation. This paper can provide some reference for predicting the reliability of domestic semiconductor devices.
