    摘要: 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.

    摘要: A non-volatile memory cell may include a semiconductor substrate; a source region in a portion of the substrate; a drain region within a portion of the substrate; a well region within a portion of the substrate. The memory cell may further include a first carrier tunneling layer over the substrate; a charge storage layer over the first carrier tunneling layer; a second carrier tunneling layer over the charge storage layer; and a conductive control gate over the second carrier tunneling layer. Specifically, the drain region is spaced apart from the source region, and the well region may surround at least a portion of the source and drain regions. In one example, the second carrier tunneling layer provides hole tunneling during an erasing operation and may include at least one dielectric layer.
