Abstract

The high-K Hf-based charge trapping layer with Al2O3 blocking oxide in metal/Al2O3/HfO2/SiO 2/silicon (MAHOS) structure is proposed. The Al2O 3 as a blocking oxide on high-κ HfO2 and HfAlO charge trapping layers can improve the program/erase speed and has good retention characteristics, indicating that the MAHOS structure is a promising candidate for future high-speed flash memory. The charge trapping characteristics with different metal gates are also investigated.
