    摘要: The present invention discloses a novel transistor structure employing semiconductive metal oxide as the transistor conductive channel. By replacing the silicon conductive channel with a semiconductive metal oxide channel, the transistors can achieve simpler fabrication process and could realize 3D structure to increase circuit density. The disclosed semiconductive metal oxide transistor can have great potential in ferroelectric non volatile memory device with the further advantages of good interfacial properties with the ferroelectric materials, possible lattice matching with the ferroelectric layer, reducing or eliminating the oxygen diffusion problem to improve the reliability of the ferroelectric memory transistor. The semiconductive metal oxide film is preferably a metal oxide exhibiting semiconducting properties at the transistor operating conditions, for example, In2O3 or RuO2. The present invention ferroelectric transistor can be a metal-ferroelectric-semiconductive metal oxide FET having a gate stack of a top metal electrode disposed on a ferroelectric layer disposed on a semiconductive metal oxide channel on a substrate. Using additional layer of bottom electrode and gate dielectric, the present invention ferroelectric transistor can also be a metal-ferroelectric-metal (optional)-gate dielectric (optional)-semiconductive metal oxide FET.

    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.
