    摘要: A method for forming a wire line by a damascene process includes forming a first insulating layer on a semiconductor substrate, etching the first insulating layer to form a contact hole, and forming a first conductive layer over the first insulating layer that fills the contact hole. The first conductive layer is patterned, and a storage node contact is formed that fills the contact hole and is electrically connected to the semiconductor substrate. A hard mask is formed over the storage node contact and the first insulating layer is etched using the hard mask as an etch mask to form a trench in the first insulating layer. A bit line is formed in the trench that is electrically connected to the semiconductor substrate. A second insulating layer is formed that covers the bit line. The second insulating layer and the hard mask are planarized and a storage node of a capacitor is formed on the storage node contact.

    摘要: A capacitor for a semiconductor memory device is fabricated by forming a mold layer on a semiconductor substrate that includes a peripheral circuit area and a cell array area which includes a plug in a buried contact hole. A hard mask layer pattern is formed on the mold layer. The mold layer is etched, using the hard mask layer pattern as an etch mask, to form a mold layer pattern. The hard mask layer pattern is then removed from the mold layer pattern or only partially etched back on the mold layer pattern. A capacitor lower electrode is formed along the walls of the buried contact hole and on a surface of the mold layer pattern. A capacitor dielectric layer is formed on the capacitor lower electrode and a capacitor upper electrode is formed on the capacitor dielectric layer.

    摘要: A method of fabricating a flash memory having a U-shape floating gate is provided. The method includes forming adjacent isolation layers separated by a gap and forming a tunnel oxide layer in the gap. After a conductive layer is formed on the tunnel oxide layer to a thickness not to fill the gap, a polishing sacrificial layer is formed on the conductive layer. The sacrificial layer and the conductive layer on the isolation layers are removed, thereby forming a U-shape floating gate self-aligned in the gap, and concurrently forming a sacrificial layer pattern within an inner portion of the floating gate. Selected isolation layers are then recessed to expose sidewalls of the floating gate. The sacrificial layer pattern is then removed from the floating gate to expose an upper surface of the floating gate.
