Abstract

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 ZrON]-[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°C, 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.
