    • A negative electrode for a rechargeable battery including: a current collector, a first layer containing a conductive material to occlude and release lithium ion, the first layer formed on the current collector, a second layer containing a metal selected from lithium and lithium alloy, the second layer formed on the first layer, and a third layer containing a lithium ion conductive material, the third layer formed on the second layer. The third layer prevents the lithium and/or the lithium alloy in the second layer from being in contact with the electrolyte and smoothly feeds the lithium to the second layer to improve the efficiency of the negative electrode. The first layer can occlude and release the part of the lithium to be occluded and released, thereby reducing the volume change of the second layer. Such a structure of the negative electrode enables us to enhance cycling efficiency, and to attain long cycle life and good safety.
    • 一种用于可再充电电池的负极,包括:集电器,包含用于封闭和释放锂离子的导电材料的第一层,形成在集电器上的第一层,含有选自锂和锂合金的金属的第二层, 第二层形成在第一层上,第三层包含锂离子传导材料,第三层形成在第二层上。 第三层防止第二层中的锂和/或锂合金与电解质接触,并平稳地将锂馈送到第二层以提高负极的效率。 第一层可以封闭和释放待封闭和释放的锂的部分,从而减少第二层的体积变化。 负极的这种结构使得我们能够提高循环效率,并且获得长的循环寿命和良好的安全性。

    • This invention provides a technique for preventing film quality of a capacitive insulating film made of a ferroelectric film of a FeRAM memory cell from being degraded and for improving the characteristics of the FeRAM memory cell. A shielding film having a higher lead content than that of a capacitive insulating film is formed under a lower electrode of a capacitor in a FeRAM memory cell, and another shielding film having a higher lead content than that of the capacitive insulating film is formed on an upper electrode. PZT films to be used as barrier layers are formed in the interlayer insulating films the FeRAM memory cell. As a result, it is possible to prevent H2 or H2O from entering an upper portion or a lower portion of the capacitor, and lead diffused from the capacitive insulating film 11a can be compensated by lead included in the shielding films, and it is possible to prevent characteristics of the capacitive insulating film 11a from being degraded.
    • 本发明提供一种用于防止由FeRAM存储单元的铁电体膜构成的电容绝缘膜的膜质量降低的技术,并且用于改善FeRAM存储单元的特性。一种屏蔽膜,其铅含量高于 电容绝缘膜形成在FeRAM存储单元中的电容器的下电极下方,并且在上电极上形成具有比电容绝缘膜高的铅含量的另一屏蔽膜。 用作阻挡层的PZT膜在FeRAM存储单元的层间绝缘膜中形成。 结果,可以防止H 2或H 2 O进入电容器的上部或下部,并且可以通过包含在屏蔽膜中的引线来补偿从电容绝缘膜11a扩散的引线,并且可以 防止电容绝缘膜11a的特性劣化。
