Ferroelectric thin films have attracted much attention for applications in nonvolatile ferroelectric random access memories(NVFeRAM) from the view points of high speed operation, low power consumption, and large scale Integration[1,2]. Among the FRAM, BLT is of particular interest. as it is not only crystallized at relatively low processing temperature, but also shows highly fatigue resistance and large remanent polarization Meanwhile, these submicron ferroelectric capacitors were fabricated by a damascene process using Chemical mechanical polishing (CMP). BLT capacitors were practicable by a damascene process using CMP. The P-E hysteresis were measured under an applied bias of ${\pm}5V$ by using an RT66A measurement system. The electric properties such as I-V were determined by using HP4155A analysers.
