Abstract
The 3D fin-channel SONOS, MONOS and MANOS type flash memories with different gate and blocking layer materials have been successfully fabricated and their electrical characteristics have been comparatively investigated. It was found that MANOS type flash memory with an Al2O3 blocking layer and a TiN metal gate shows the better performance as compared to the SONOS and MONOS type ones thanks to the high-k effect of Al2O3 and the high gate work function of TiN.
