    摘要: A plug comprises a first insulating interlayer, a tungsten pattern and a tungsten oxide pattern. The first insulating interlayer has a contact hole formed therethrough on a substrate. The tungsten pattern is formed in the contact hole. The tungsten pattern has a top surface lower than an upper face of the first insulating interlayer. The tungsten oxide pattern is formed in the contact hole and on the tungsten pattern. The tungsten oxide pattern has a level face.

    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 phase-change memory device including a first contact region and a second contact region formed on a semiconductor substrate. A first insulating layer with a first contact hole and a second contact hole is disposed on the semiconductor substrate, exposing the first and second contact regions. A first conductive layer is disposed on the first insulating interlayer to fill the first and the second contact holes. A first protection layer pattern and a lower wiring protection pattern are disposed on the first conductive layer. A first contact with a first electrode and a second contact with a lower wiring are disposed so as to connect the first and second contact regions. A second protection layer with a second electrode is disposed on the first protection layer pattern and the lower wiring protection pattern. A via filled with a phase-change material is disposed between the first electrode and the second electrode.

    摘要: Methods of forming ferroelectric layers include forming a ferroelectric layer on a substrate and chemically-mechanically polishing a surface of the ferroelectric layer by rotating a polishing pad on the surface at a rotation speed in a range from about 5 rpm to about 25 rpm. This polishing step includes pressing the polishing pad onto the surface of the ferroelectric layer at a pressure in a range from about 0.5 psi to about 3 psi. This polishing step may be followed by the step of exposing the polished surface to a rapid thermal anneal. This anneal can be performed in an inert atmosphere containing a gas selected from a group consisting of nitrogen, helium, argon and neon.
