    Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a memory element that prevents degradation in characteristics due to high temperature annealing after formation of element, and can be applied as a multi-use memory device.
    SOLUTION: A high resistance layer 3A consisting of an oxide of a metal element, and an ion source layer 3B containing metal elements (Cu, Ag, Zn) becoming an ion source are provided in this order between a lower electrode 2 and an upper electrode 4. When the high resistance layer 3A is formed after the lower electrode 2, superfluous oxygen in the high resistance layer 3A is discharged by performing annealing at a temperature equal to or higher than the annealing temperature in subsequent annealing (after formation of element). An oxide of such an element as Ta, Hf, Si, Ni or Co, or an rare earth element (e.g., Gd or Ce) is employed in the high resistance layer 3A. Annealing may be performed after forming the lower electrode 2 and before forming the high resistance layer 3A.

A resist film 14 is formed on the laminated body 13 and is baked, and another resist film 15 is formed thereon. Then the laminated body 13 is exposed to a discriminating pattern and the resist films 14, 15 are developed. The resist film 15 is removed by the development except for the part corresponding to the discriminating pattern, and the resist film 14 is etched at the side to form the plural kinds of discriminating resists 17. The laminated body 13 except for the region of the discriminating resist 17 is removed by etching to expose a lower gap layer 4, which prevents the generation of burr.
