摘要:
Methods of forming a gate structure for an integrated circuit memory device include forming a metal oxide dielectric layer on an integrated circuit substrate. Ions of a selected element from group 4 of the periodic table and having a thermal diffusivity of less than about 0.5 centimeters per second (cm2/s) are injected into the dielectric layer to form a charge storing region in the dielectric layer with a tunnel dielectric layer under the charge storing region and a capping dielectric layer above the charge storing region. The substrate including the metal oxide dielectric layer is thermally treated to form a plurality of discrete charge storing nano crystals in the charge storing region. A gate electrode layer is formed on the dielectric layer.

Methods of forming a gate structure for an integrated circuit memory device include forming a first dielectric layer having a dielectric constant of under 7 on an integrated circuit substrate. Ions of a selected element from group 4 of the periodic table and having a thermal diffusivity of less than about 0.5 centimeters per second (cm2/s) are injected into the first dielectric layer to form a charge storing region in the first dielectric layer with a tunnel dielectric layer under the charge storing region. A metal oxide second dielectric layer is formed on the first dielectric layer, the second dielectric layer. The substrate including the first and second dielectric layers is thermally treated to form a plurality of discrete charge storing nano crystals in the charge storing region and a gate electrode layer is formed on the second dielectric layer. Gate structures for integrated circuit devices and memory cells are also provided.

摘要:
A semiconductor device includes a substrate, a gate electrode on the substrate and source and drain electrodes disposed at respective sides of the gate electrode. The device further includes a nano-line passing through the gate electrode and extending into the source and drain electrodes and having semiconductor characteristics. The nano-line may include a nano-wire and/or a nano-tube. A gate insulating layer may be interposed between the nano-line and the gate electrode. The source and drain electrodes may be disposed adjacent respective opposite sidewalls of the gate electrode, and the gate insulating layer may be further interposed between the source and drain electrodes and the gate electrode. Fabrication methods for such devices are also described.
