    摘要: A method of fabricating a non-volatile memory is provided. The method includes providing a substrate. Next, a tunneling oxide layer is formed on the substrate and a surface nitridation process is performed to nitridize the upper surface of the tunneling oxide layer. A plurality of nanocrystals is formed on the nitridized surface of the tunneling oxide layer. Next, the surfaces of the nanocrystals are nitridized. An oxide layer and a conductive layer are formed in sequence over the tunneling oxide layer to cover the nanocrystals. Due to the formation of high-density nanocrystals as a charge storage medium, the properties of the memory are enhanced.

    摘要: A flash memory structure comprises a semiconductor substrate having a V-groove, a first doped region positioned in the semiconductor substrate, two second doped regions positioned in the semiconductor substrate and at two sides of the V-groove, a dielectric stack having trapping sites interposed therein positioned on the V-groove, and a conductive layer positioned on the surface of the dielectric stack above the V-groove. A method for forming the V-groove comprises steps of forming a mask layer on the surface of the semiconductor substrate, forming an opening in the mask layer, etching a portion of the semiconductor substrate below the opening to form the V-groove, and removing the mask layer. The semiconductor substrate can be a (100)-oriented silicon substrate, and the V-groove has inclined surface planes with (111) orientation.
