    摘要: A method for fabricating a floating gate memory device comprises using thin buried diffusion regions with increased encroachment by a buried diffusion oxide layer into the buried diffusion layer and underneath the tunnel oxide under the floating gate. Further, the floating gate polysilicon layer has a eight than the buried diffusion height. The increased step height of the gate polysilicon layer to the buried diffusion layer, and the increased encroachment of the buried diffusion oxide, can produce a higher GCR, while still allowing decreased cell size using a virtual ground array design.

    摘要: A method for fabricating a non-volatile memory is provided. A dielectric layer, a first conductive layer, and a mask layer are formed sequentially on a substrate and then patterned to form a number of openings and floating gates. In addition, spacers are formed on the sidewalls of the openings. A source/drain region is formed in the substrate underneath each of the openings. A thermal process is performed to oxidize the substrate exposed by the opening to form an insulating layer above the source/drain region. Afterward, the mask layer is removed and an inter-gate dielectric layer is formed to cover the surface of the first conductive layer and the surface of the insulating layer. Subsequently, a second conductive layer is formed on the inter-gate dielectric layer.

A substrate having a pad dielectric layer and a first dielectric layer thereon is provided. Then a buried diffusion region is formed in the substrate. Next a second dielectric layer is formed over the substrate and the second dielectric layer and the pad dielectric layer are then etched back to expose the buried diffusion region and the first dielectric layer. Then a shallow trench isolation is formed into the expose the buried diffusion region and the substrate. Next a floating gate pattern is transferred into the first and second dielectric layers. Next the first dielectric layer is removed to expose the pad dielectric layer. Then the exposed pad dielectric layer is removed to expose the substrate. Next a tunnel dielectric layer is formed on the exposed substrate. Next a first conductive layer is conformally formed over the substrate and is planarized to expose the shallow trench isolation. Then an inter gate dielectric layer is formed over the first conductive layer and the shallow trench isolation. Finally a second conductive layer is formed over the inter gate dielectric layer.
