摘要

We report a flash memory using deep traps nano-dot formed in ZrON charge trapping layers by As~+ implantation to improve the device performance of MONOS CTF device. The TaN-[SiO_2-LaAlO_3]-[As~+-implanted Zr0N]-[LaAlO_3-SiO_2]-Si device shows a 6 nm ENT, a large initial memory window of 9.8 V, a 10-year extrapolated retention window of 3.6 V at 85℃, and an endurance window of 5.1 V after 10~5 cycles under fast 100 μs and low ±16 V program/erase. The performance of As~+-implanted ZrON is significantly better than that of stacked Si_3N_4/Ir-dot/HfON device with poor thickness scaling due to excess Ir metal dot.
