钇改性PZT薄膜的极化印刻研究
Imprint Properties of Yttrium Modified PZT Thin Films
【摘要】 铁电PZT薄膜的极化印刻(imprinting)是PZT不挥发存储器失效的重要原因之一.本文研究了不同钇量改性的PZT(40/60)铁电薄膜在高温(120℃)和偏置电压下的极化印刻特性,发现适量的钇掺杂,改善了PZT薄膜电容器单元的极化印刻.
【Abstract】 Imprint failure is one of the important failure mechanisms for PZT nonvolatile memo- ries. The imprint properties of Y-dopped PZT(40/60) thin films at bias voltages and a temperature of 120℃ were investigated. The results obtained show that the imprint-resistant properties of the PZT thin films are enhanced by a suitable Y dopant concentration.
