Abstract

Endurance ~ 1012 cycling of ferroelectric (FE) and antiferroelectric (AFE) HfZrO2 (HZO) capacitors are achieved experimentally by adjusting the programming pulse width (tp). The correlation between switching polarization (△P) and fatigue behavior of high endurance is discussed. For long tp (= 1 μs), AFE exhibits excellent endurance with > 1010 cycles as compared with FE ~ 109 cycles. With shortening tP, the endurances of FE and AFE are significantly improved. There is no significant degradation until > 1011 cycling is observed for FE with tp=20ns.
