    摘要: A double pattern method of forming a plurality of contact holes in a material layer formed on a substrate is disclosed. The method forms a parallel plurality of first hard mask patterns separated by a first pitch in a first direction on the material layer, a self-aligned parallel plurality of second hard mask patterns interleaved with the first hard mask patterns and separated from the first hard mask patterns by a buffer layer to form composite mask patterns, and a plurality of upper mask patterns in a second direction intersecting the first direction to mask selected portions of the buffer layer in conjunction with the composite mask patterns. The method then etches non-selected portions of the buffer layer using the composite hard mask patterns and the upper mask patterns as an etch mask to form a plurality of hard mask holes exposing selected portions of the material layer, and then etches the selected portions of the material layer to form the plurality of contact holes.

    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 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.
