The effect of integration of strontium-bismuth-tantalate capacitors onto SOI wafers

Abstract

We report for the first time the successful integration of strontium-bismuth-tantalate ferroelectric capacitors on an SOI substrate. We have verified that the unique processing requirements of SBT capacitors do not affect the properties of the surrounding FD-SOI transistors, and, conversely, we have verified that the SOI processing does not affect the quality of the SBT capacitors.
