    摘要: A device and method for forming a capacitor device comprises forming a substrate, forming a first interlayer dielectric layer on the substrate and forming two or more contact plugs through the substrate. A conducting layer is formed on the first interlayer dielectric layer and an electrode is formed on alternate ones of the contact plugs by etching the conducting layer. The etched electrodes are then coated with a ferroelectric layer. The ferroelectric layer is etched from the surfaces separating the contact plugs and additional electrodes are created by filling the spaces between the electrodes on alternate ones of the contact plugs with a conductive material to establish electrical contact between the plugs and the electrodes.

    摘要: In a process for fabricating a ferrocapacitor comprising providing ferroelectric PZT elements over an Al2O3 layer, the Al2O3 layer is covered with a seed layer comprising layers of PZT and TiO2. Then a thicker layer of PZT is formed over the seed layer and crystallized. By this process, the crystallinity of the thick PZT layer is much improved, and its orientation is improved to be in the (111) direction. Furthermore, the seed layer reduces downward diffraction of Pb from the thick PZT layer, such as through the Al2O3 into a TEOS structure beneath.

    摘要: The process provides a multistage procedure, in which, in the first step the layer is sputtered at low temperature, in the second step an RTP process is carried out in an inert atmosphere at medium or high temperature, and in the third step the layer is heat treated in an atmosphere containing oxygen at low or medium temperature. The levels of heating are considerably reduced compared with conventional processes, so that when the process is being employed for producing an integrated memory cell it is possible to prevent oxidation of an underlying barrier layer.
