  • Patent number: 7785965
    Abstract: Dual storage node memory devices and methods for fabricating dual storage node memory devices have been provided. In accordance with an exemplary embodiment, a method includes the steps of etching a plurality of trenches in a semiconductor substrate and forming a layered structure within the trenches. The layered structure includes a tunnel dielectric layer and a charge storage layer. Bit lines are formed within the semiconductor substrate and a layer of conductive material is deposited overlying the layered structure.

  • Publication number: 20100099249
    Abstract: Methods of selectively forming metal silicides on a memory device are provided. The methods can include forming a mask layer over the memory device; forming a patterned resist over the mask layer; removing upper portions of the patterned resist; forming a patterned mask layer by removing portions of the mask layer that are not covered by the patterned resist; and forming metal silicides on the memory device by a chemical reaction of a metal layer formed on the memory device with portions of the memory device that are not covered by the patterned mask layer. By preventing silicidation of underlying silicon containing layers/components of the memory device that are covered by the patterned mask layer, the methods can selectively form the metal silicides on the desired portions of the memory device.

  • Patent number: 7622389
    Abstract: A method for manufacturing a semiconductor device including selective conductive contacts includes the step of depositing a resist over first and second memory device components, each of the first and second components comprising junctions formed in the substrate and a gate formed on the substrate between the junctions. The resist is then removed from the second components to thereby form a resist opening above each of the second component control gates and junctions. The resist is then etched to thereby expose each of the first component control gates but not the substrate surrounding the first component control gates. Conductive contacts are then formed on the exposed first component control gates, and the second component control gates and junctions.

  • Publication number: 20090140325
    Abstract: A method of forming an electronic device is provided that includes selectively implanting ions into a workpiece, wherein ions are implanted into a first region of the workpiece that includes a semiconductor material, while substantially none of the ions are implanted into a second region of the workpiece that also includes a semiconductor material. The method further includes depositing a metal-containing film over the first region and the second region after selectively implanting, and then reacting the metal-containing film with the semiconductor material to form a first metal-semiconductor film within the first region and a second metal-semiconductor film within the second region. The first metal-semiconductor film has a first thickness and the second metal-semiconductor film has a second thickness that is different from the first thickness.

  • Publication number: 20080149989
    Abstract: Flash memory devices and methods for fabricating the same are provided. In accordance with an exemplary embodiment of the invention, a method for fabricating a memory device comprises the steps of fabricating a first gate stack and a second gate stack overlying a substrate. A trench is etched into the substrate between the first gate stack and the second gate stack and a first impurity doped region is formed within the substrate underlying the trench. The trench is filled at least partially with a conductive material.
