This brief investigates the random grain-boundary (GB)-induced variability in poly-crystalline silicon thin-film transistor for stackable NAND flash applications using 3-D Voronoi grain patterns. Compared with the 1-D and 2-D methods, the 3-D Voronoi grain can show a more realistic threshold-voltage variability when devices are downscaled along the channel height direction. Therefore,...
In this work, we employ a novel Voronoi approach to simulate the impact of trap states in the poly-Si channel. Using this method, we investigate the grain boundary induced threshold voltage variability in stackable NAND flash memories. Our study indicates that considering the randomized shape and location of grain boundaries is crucial to the modeling and simulation of these devices.
