PbZrTiO 3 (PZT) is one of the most promising ferroelectric materials for ferroelectric random access memory (FeRAM). But, there is a problem that the PZT ferroelectric properties are degraded with platinum (Pt) electrodes after annealing in a hydroge

(Pb, La)(Zr, Ti)O3[PLZT] films were prepared by CSD on sputtered electrodes of Pt/IrO2 on SiO2/Si wafers. Top electrodes consisting of Pt/SrRuO3(SRO) were sputter deposited and the Pt/SRO/PLZT/Pt capacitors were annealed at 600°C. Evaluation of fati

We propose an analytical expression for dose dependent ion-implanted impurity concentration profiles using a main function and a tail function. The main function describes the profile near the peak region and the tail function describes the channelin

PZT is promising material for FeRAM. It has a serious problem on the CMOS wafer process that electrical properties are degraded with forming gas annealing. Recently, the degradation mechanism has been investigated actively, but it isn't understood en

This paper presents the results of a study on the effects of N2-H2 annealing on Pt/PZT/Pt capacitors. By measuring the electrical properties of test capacitors before and after annealing and comparing the data with composition profiles obtained via s

The relationship between Sr interdiffusion from a Pt/SrRuO3 [SRO] top electrode into (Pb, La)(Zr, Ti)O3 [PLZT] ferroelectric thin films with different excess Pb contents (2–10%) and leakage properties was studied. Secondary ion mass spectrometry an
