Abstract

A method for manufacturing a non-volatile memory device is described. The method comprises growing a layer in a siliconoxide consuming material, e.g. DyScO, on top of the upper layer of the layer where charge is stored. A non-volatile memory device is also described. In the non-volatile memory device, the interpoly/blocking dielectric comprises a layer in a siliconoxide consuming material, e.g. DyScO, on top of the upper layer of the layer where charge is stored, the siliconoxide consuming material having consumed at least part of the upper layer.
