    摘要: In an embodiment, a chemical mechanical polishing method for a substrate having a first layer and a stepped portion. A surface of the first layer is positioned above an upper face of the stepped portion. A polishing process for selectively removing the stepped portion is performed on the first layer by using a first slurry composition that has a self-stopping characteristic so that the first layer is changed into a second layer having a substantially flat surface. A second polishing process is performed using a second slurry composition that does not have the self-stopping characteristic, until the upper face of the stepped portion is exposed.

    摘要: Methods of forming non-volatile memory devices include the steps of forming a semiconductor substrate having first and second floating gate electrodes thereon and an electrically insulating region extending between the first and second floating gate electrodes. A step is then performed to etch back the electrically insulating region to expose upper corners of the first and second floating gate electrodes. Another etching step is then performed. This etching step includes exposing upper surfaces and the exposed upper corners of the first and second floating gate electrodes to an etchant that rounds the exposed upper corners of the first and second floating gate electrodes. The step of etching back the electrically insulating region includes etching back the electrically insulating region to expose sidewalls of the first and second floating gate electrodes having heights ranging from about 30 Å to about 200 Å. The step of exposing the upper corners of the first and second floating gate electrodes to an etchant is followed by the step of etching back the electrically insulating region to expose entire sidewalls of the first and second floating gate electrodes.

    摘要: Provided is a semiconductor device including a vertically oriented capacitor extending above the substrate surface and a method of manufacturing such devices in which cell, peripheral and boundary areas between the cell and peripheral areas are defined on a semiconductor substrate. Capacitors are formed in the cell area, a mold pattern is provided in the peripheral areas and an elongated dummy pattern is provided in the boundary areas. The dummy pattern includes a boundary opening in which a thin layer is formed on the elongated inner sidewalls and on the exposed portion of the substrate during formation of the lower electrode. A mold pattern and lower electrode structures having substantially the same height are then formed area so that subsequent insulation interlayer(s) exhibit a generally planar surface, i.e., have no significant step difference between the cell areas and the peripheral areas.
