    摘要: A method for forming a memory device is provided. A nitride layer is formed over a substrate. The nitride layer and the substrate are etched to form a trench. The memory device is pre-cleaned to prepare a surface of the memory device for oxide formation thereon, where cleaning the memory device removes portions of the barrier oxide layer on opposite sides of the trench. The nitride layer is trimmed on opposite sides of the trench. A liner oxide layer is formed in the trench.

    摘要: A memory device may include a substrate, a first dielectric layer formed over the substrate and a charge storage element formed over the first dielectric layer. The memory device may also include a second dielectric layer formed over the charge storage element and a third dielectric layer formed over the second dielectric layer. The third dielectric layer may have a high dielectric constant and may be deposited at a relatively high temperature. A control gate may be formed over the third dielectric layer.
