    摘要: A method of monitoring synthesis of PCMO precursor solutions includes preparing a PCMO precursor solution and withdrawing samples of the precursor solution at intervals during a reaction phase of the PCMO precursor solution synthesis. The samples of the PCMO precursor solution are analyzed by UV spectroscopy to determine UV transmissivity of the samples of the PCMO precursor solution and the samples used to form PCMO thin films. Electrical characteristics of the PCMO thin films formed from the samples are determined to identify PCMO thin films having optimal electrical characteristics. The UV spectral characteristics of the PCMO precursor solutions are correlated with the PCMO thin films having optimal electrical characteristics. The UV spectral characteristics are used to monitor synthesis of future batches of the PCMO precursor solutions, which will result in PCMO thin films having optimal electrical characteristics.

    摘要: The present invention discloses a ferroelectric transistor having a conductive oxide in the place of the gate dielectric. The conductive oxide gate ferroelectric transistor can have a three-layer metal/ferroelectric/metal or a two-layer metal/ferroelectric on top of the conductive oxide gate. By replacing the gate dielectric with a conductive oxide, the bottom gate of the ferroelectric layer is conductive through the conductive oxide to the silicon substrate, thus minimizing the floating gate effect. The memory retention degradation related to the leakage current associated with the charges trapped within the floating gate is eliminated. The fabrication of the ferroelectric transistor by a gate etching process or a replacement gate process is also disclosed.
