  • Patent number: 6080616
    Abstract: A memory cell is formed including an insulation region on the substrate and a transistor including a gate on the substrate and a source/drain region in the substrate disposed between the gate and the insulation region. The cell also includes a capacitor including an electrode overlying the insulation region, the electrode having a lateral surface adjacent the source/drain region. A conductive interconnecting region is formed on the substrate and extends from the source/drain region to contact the lateral surface of the first electrode of the capacitor. The capacitor may include a first electrode on the insulation region, a dielectric region on the first electrode, and a second electrode on the dielectric region. The first electrode preferably is platinum and the dielectric region preferably is a ferroelectric material such as lead zirconate titanate (PZT) or Ba.sub.x Sr.sub.1-x TiO.sub.3 (BST).
