    摘要: Methods are provided for fabricating contacts in integrated circuit devices, such as phase-change memories. A protection layer and a sacrificial layer are sequentially formed on a semiconductor substrate. A contact hole is formed through the sacrificial layer and the protection layer. A conductive layer is formed on the sacrificial layer and in the contact hole, and portions of the conductive layer and the sacrificial layer are removed to expose the protection layer and form a conductive plug protruding from the protection layer. A protruding portion of the conductive plug removed to leave a contact plug in the protection layer. A phase-change data storage element may be formed on the contact plug.

    摘要: A method of fabricating a phase change memory device includes the use of first, second and third polishing processes. The first polishing process forms a first contact portion using a first sacrificial layer and the second polishing process forms a phase change material pattern using a second sacrificial layer. After removing the first and second sacrificial layers to expose resultant protruding structures of the first contact portion and the phase change material pattern, a third polishing process is used to polish the resultant protruding structures using an insulation layer as a polishing stopper layer.

    摘要: A method of fabricating a semiconductor device including a channel layer includes forming a single crystalline semiconductor layer on a semiconductor substrate. The single crystalline semiconductor layer includes a protrusion extending from a surface thereof. A first polishing process is performed on the single crystalline semiconductor layer to remove a portion of the protrusion such that the single crystalline semiconductor layer includes a remaining portion of the protrusion. A second polishing process different from the first polishing process is performed to remove the remaining portion of the protrusion and define a substantially planar single crystalline semiconductor layer having a substantially uniform thickness. A sacrificial layer may be formed on the single crystalline semiconductor layer and used as a polish stop for the first polishing process to define a sacrificial layer pattern, which may be removed prior to the second polishing process. Related methods of fabricating stacked semiconductor memory devices are also discussed.
