  • Publication number: 20080003739
    Abstract: A method for forming an isolation structure of a flash memory device includes providing a substrate structure where a tunnel insulating layer, a conductive layer, and a padding layer are formed, etching the padding layer, the conductive layer, the tunnel insulating layer and the substrate to form a trench, forming a first insulating layer over the substrate structure and filling in a portion of the trench, forming a second insulating layer over the substrate structure, forming a third insulating layer over the substrate structure to fill the trench, polishing the first, second and third insulating layers using the padding layer as a polish stop layer, removing the padding layer and simultaneously recessing the third insulating layer to protrude the first and second insulating layers, and etching the first and second insulating layers while recessing the third insulating layer to form a protective layer on sidewalls of the conductive layer.

  • Publication number: 20080003831
    Abstract: A method for forming a metal pattern in a semiconductor device includes preparing a semi-finished substrate with a metal layer for use as a metal pattern, performing a cleaning process inducing oxidation over an upper surface of the metal layer to form an anti-scattering reflection layer over the upper surface of the metal layer, forming a photoresist pattern over the anti-scattering reflection layer, and etching the anti-scattering reflection layer and the metal layer exposed by the photoresist pattern to form the metal pattern.
