Abstract:
1. A method for manufacturing a memory element, comprising the steps of: forming a first conductive layer; forming a composition layer over the first conductive layer by discharging a composition in which nanoparticles comprising a conductive material covered with an organic material are dispersed in a solvent; drying the composition layer; and decomposing the organic material covering the nanoparticles which are positioned on the surface of the composition layer such that a memory layer comprising the nanoparticles covered with the organic material and a second layer comprising the nanoparticles not covered with the organic material are formed in the composition layer, wherein the memory layer is closer to the first conductive layer than the second layer; forming a second conductive layer by sintering of the nanoparticles not covered with the organic material in the second layer.
