摘要
NBTI效应严重影响了器件的高温可靠性,本文对基于1.2μm工艺的PDSOI器件进行了NBTI效应研究。通过加速应力试验得到了NBTI效应对PDSOI器件阈值电压漂移的影响,其主要影响因素有应力时间、温度和栅偏压。试验中通过Vg模型对PDSOI器件进行了NBTI效应寿命预测,实现了对自有1.2μm工艺PDSOI器件的高温可靠性评价。
The NBTI effect seriously affects the high temperature reliability of the device.In this paper,the NBTI effect of 1.2μm process Partially Depleted Silicon On Insulator(PDSOI)device was studied.Acceleration stressing experiments were made to obtain threshold voltage shift of PDSOI device effected by NBTI.The main influencing factors are stress time,temperature and gate bias voltage.Through the Vg model,the NBTI effect lifetime of PDSOI device is estimated which can be used to evaluate the high temperature reliability of 1.2μm process PDSOI device.
