Abstract

Highly scaled MOSFETs are suffering from various fluctuations. In this paper, an artificial neural network (ANN) device modeling technique is reported for gate-all-around silicon nanosheet MOSFETs (GAA Si NS MOSFETs). The well-trained ANN model can rapidly and accurately estimate the effect of work function fluctuation (WKF) on device characteristic. Our model is generic because it can be successfully evaluated on the device with a ferroelectric HZO layer which have material and structural dissimilarity with the GAA NS device.
