    摘要: An encapsulated capacitor structure and method for fabricating same. The capacitor structure is created by selectively depositing a lower electrode, a dielectric thin film of BST or other ferrodielectric, and an upper electrode, onto a substrate, and subsequently depositing a conformal layer of a non-reductively deposited dielectric material. Contact windows are then opened through the encapsulating layer for contacting the capacitor electrodes. The underlying structure is protected by the encapsulating layer from metal deposition and post-processing which would otherwise damage the structure.

    摘要: A silicon nitride barrier layer is deposited on a gallium arsenide substrate to prevent evaporation of the substrate in subsequent heating steps. A silicon dioxide stress reduction layer is deposited on the barrier layer. A first electrode is formed on the stress reduction layer, then a liquid precursor is spun on the first electrode, dried at about 400° C., and annealed at between 600° C. and 850° C. to form a BST capacitor dielectric. A second electrode is deposited on the dielectric and annealed.
