Abstract

A patterned composite ferroelectric layer, having ferroelectric electronic properties, on a substrate. Individual layers are each made of metal acrylate compounds, a photoinitiator compound and an acrylate crosslinking compound. The individual layers are stacked on the substrate to form a composite layer. A photomask is formed on the composite layer. Unmasked areas of the composite layer are irradiated with ultraviolet light. A solvent removes non-irradiated areas of the composite layer from the substrate. The patterned composite layer is heated in an oxygen atmosphere to cause a chemical reaction among the metal acrylate compounds and oxygen, a patterned composite ferroelectric layer being formed on the substrate.
