发明名称 Fabrication method of non-volatile memory
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.
