    摘要: Various embodiments provide memory devices and methods for forming the same. A substrate is provided, the substrate having one or more adjacent memory cells formed thereon. Each memory cell includes a gate structure, a control gate layer, and a first mask layer. A portion of the control gate layer is removed, to reduce a size of an exposed portion of the control gate layer in a direction parallel to a surface of the substrate. An electrical contact layer is formed on an exposed sidewall of the control gate layer and an exposed surface of the substrate. A barrier layer is formed on a sidewall of the memory cell. A conductive structure is formed on the substrate. The conductive structure has a significantly larger distance from control gate layer than from the gate structure, and the barrier layer forms an isolation layer between the conductive structure and the control gate layer.

    摘要: A back-end metallization structure for non-volatile memory (NVM) and other semiconductor devices including low-moisture-content oxide cap layers that suppress the creation and migration of mobile hydrogen atoms/ions during back-end processing. The metallization structure includes multiple metallization layers formed over front-end e.g., polysilicon (floating gate) structures and a pre-metal dielectric layer. Each metallization layer includes a patterned metal (e.g., aluminum) structure covered by an interlevel dielectric (ILD) layer (e.g., BPSG, USG or FSG). Each cap layer is formed using a high-density low-moisture content oxide such as silane oxide (i.e., SiO2 generated by way of a silane CVD process) that is deposited over the ILD layer in lower metallization layers to serve as an etch-stop for the subsequently-formed metal layer, and to isolate the ILD material from the plasma environment during aluminum over etch, which significantly reduces the production and migration of hydrogen that diminishes charge storage by the floating gates.

    摘要: Semiconductor devices include one or more transistors having a floating gate and a control gate. In at least one embodiment, the floating gate comprises an intermediate portion extending between two end portions. The intermediate portion has an average cross-sectional area less than one or both of the end portions. In some embodiments, the intermediate portion may comprise a single nanowire. In additional embodiments, semiconductor devices have one or more transistors having a control gate and a floating gate in which a surface of the control gate opposes a lateral side surface of a floating gate that defines a recess in the floating gate. Electronic systems include such semiconductor devices. Methods of forming semiconductor devices include, for example, forming a floating gate having an intermediate portion extending between two end portions, and configuring the intermediate portion to have an average cross-sectional area less than one or both of the end portions.
