    摘要: A methods of forming a flash memory device are provided. The flash memory device comprises a silicon dioxide layer on a substrate and a silicon nitride layer that is formed on the silicon dioxide layer. The properties of the silicon nitride layer can be modified by any of: exposing the silicon nitride layer to ultraviolet radiation, exposing the silicon nitride layer to an electron beam, and by plasma treating the silicon nitride layer. A dielectric material is deposited on the silicon nitride layer and a conductive date is formed over the dielectric material. The flash memory device with modified silicon nitride layer provides an increase in charge holding capacity and charge retention time of the unit cell of a non-volatile memory device.
