  • Patent number: 7763935
    Abstract: A method of fabricating a non-volatile memory device at least comprises steps as follows. First, a substrate on which a bottom dielectric layer is formed is provided. Then, impurities are introduced through the bottom dielectric layer to the substrate, so as to form a plurality of spaced doped regions on the substrate. The structure is thermally annealed for pushing the spaced doped regions to diffuse outwardly. After annealing, a charge trapping layer is formed on the bottom dielectric layer, and a top dielectric layer is formed on the charge trapping layer. Finally, a gate structure (such as a polysilicon layer and a silicide) is formed on the top dielectric layer.

  • Patent number: 7118968
    Abstract: Roughly described, a floating gate memory cell is fabricated by forming an oxide-nitride dielectric layer above a floating gate of the memory cell and in an oxide growth region not above a floating gate. The nitride layer is removed in the oxide growth region using a mask that protects the nitride layer above the floating gate, and then the bottom oxide layer is removed in the oxide growth region using a wet etch that does not affect the nitride remaining above the floating gate. First and second oxide layers are then formed both above the floating gate and in the oxide growth region, to act as the top layer of ONO above the floating gate and as the gate oxide in the oxide growth region. One of the first and second oxide layers is formed using in-situ steam generation.
