Abstract
A method for forming a patterned ferroelectric layer, having ferroelectric electronic properties, on a substrate. A composite layer, made of ferroelectric layer producing metal acrylate compounds, a photoinitiator compound and an acrylate crosslinking compound is formed on the substrate. 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 ferroelectric layer producing metal acrylate compounds and oxygen, a patterned ferroelectric layer being formed on the substrate.
