    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.

    摘要: In one aspect, a method of fabricating a semiconductor memory device is provided which includes forming a mold insulating film over first and second portions of a semiconductor substrate, where the mold insulating film includes a plurality of storage node electrode holes spaced apart over the first portion of the semiconductor substrate. The method further includes forming a plurality of storage node electrodes on inner surfaces of the storage node electrode holes, respectively, and forming a capping film which covers the storage node electrodes and a first portion of the mold insulating film located over the first portion of the semiconductor substrate, and which exposes a second portion of the mold insulating film located over the second portion of the semiconductor substrate. The method further includes selectively removing, including wet etching, the mold insulating film to expose a sidewall of at least one storage node electrode among the storage node electrodes covered by the capping film, and removing the capping film by dry etching to expose upper portions of the storage node electrodes.
