Abstract:
A nonvolatile memory element comprising: a first electrode 2; a second electrode 6 formed above the first electrode 2; a variable resistance film 4 formed between the first electrode 2 and the second electrode 6, a resistance value of the variable resistance film 4 being increased or decreased by an electric pulse applied between the first and second electrodes 2, 6; and an interlayer dielectric film 3 provided between the first and second electrodes 2, 6, wherein the interlayer dielectric film 3 is provided with an opening extending from a surface thereof to the first electrode 2; the variable resistance film 4 is formed at an inner wall face of the opening; and an interior region of the opening which is defined by the variable resistance film 4 is filled with an embedded insulating film 5.
