The first insulating interlayer has top surface, a height of which is greater in the first region than in the second region. A first planarization stop layer and a second insulating interlayer are formed. The second insulating interlayer is planarized until the first planarization stop layer is exposed. The first planarization stop layer and the first and second insulating interlayers in the second region are removed to expose the substrate.

    摘要： A phase changeable memory device is manufactured by forming at least one insulating layer on a substrate. A preliminary first electrode is formed on the insulating layer. The preliminary first electrode is partially etched to form a first electrode electrically connected to the substrate. After the preliminary first electrode is formed, both sidewalls of the preliminary first electrode are partially etched isotropically to form a first electrode having a uniform width and height. A phase changeable material layer pattern and a second electrode are subsequently formed on the first electrode. Related devices also are described.

    摘要： A method of manufacturing a semiconductor device includes forming an insulation pattern over a substrate. The insulation pattern has at least one opening that exposes a surface of the substrate. Then, a first polysilicon layer is formed over the substrates such that the first polysilicon layer fills the opening. The first polysilicon layer also includes a void therein. An upper portion of the first polysilicon layer is removed such that void expands to a recess and the recess is exposed. A second polysilicon layer is formed over the substrate such that the second polysilicon layer fills the recess.

    摘要： Methods of manufacturing a semiconductor device are provided. A trench is formed in a semiconductor substrate. A first field oxide layer is formed that partially fills the trench. The first field oxide layer defines an active region of the substrate that is adjacent to the trench. An upper portion of sidewalls of the trench extends upward beyond a surface of the first field oxide layer. A first liner is formed on the first field oxide layer and on the portion of the sidewalls of the trench that extend upward beyond the first field oxide layer. A second field oxide layer is formed on the first liner and fills the trench. The second field oxide layer and the first liner are each partially removed to expose a top adjacent surface and upper sidewalls of the trench along the active region of the substrate. A dielectric layer is formed on the exposed top adjacent surface and upper sidewalls of the trench. A gate electrode is formed on the dielectric layer.
