    摘要: A method and structure for a memory device, such as a 1T-SRAM, having a capacitor top plate directly over a doped bottom plate region. An example device comprises the following. An isolation film formed as to surround an active area on a substrate. A gate dielectric and gate electrode formed over a portion of the active area. A source element and a drain element in the substrate adjacent to the gate electrode. The drain element is comprised of a drain region and a bottom plate region. The drain region is between the bottom plate region and the gate structure. A capacitor dielectric and a capacitor top plate are over at least portions of the bottom plate region.

    摘要: Embodiments of the invention provide a method of forming a field-effect-transistor (FET). The method includes implanting one or more n-type dopants to create one or more implanted regions with at least a portion of the implanted regions being designated as regions for forming source and drain extensions of the FET; activating the implanted regions; etching with a chlorine based etchant to create openings in the implanted regions, and forming the source and drain extensions by exptaxially growing embedded silicon germanium in the openings. Structure of a semiconductor field-effect-transistor made thereof is also provided.
