  ABSTRACT: Doubly stacked nanocrystalline-Si (nc-Si) based metal insulator semiconductor memory structure was fabricated by plasma enhanced chemical vapor deposition. Capacitance-Voltage (C-V) and capacitance-time (C-t) measurements were used to investigate electron tunnel, storage and discharging characteristic. The C-V results show that the flatband voltage increases at first, then decreases and finally increases, exhibiting a clear deep at gate voltage of 9 V. The de-creasing of flatband voltage at moderate programming bias is attributed to the transfer of electrons from the lower nc-Si layer to the upper nc-Si layer. The C-t measurement results show that the charges transfer in the structure strongly de-pends on the hold time and the flatband voltage decreases markedly with increasing the hold time.
