摘要:
An apparatus for depositing a thin film on a substrate includes a housing, a substrate support portion, a securing member, a heater, a target member and a plasma generator. The housing defines a process chamber. The substrate support portion is disposed in the process chamber to support the substrate. The securing member is adapted to non-electrically secure the substrate to the substrate support portion during performance of a process. The heater is provided to maintain the substrate supported by the substrate support portion at a process temperature. The target member faces the substrate support portion and includes materials to be deposited on the substrate. The plasma generator is adapted to excite a process gas supplied into the process chamber into a plasma state.
摘要:
A FRAM having a ferroelectric capacitor comprises a cylindrical type bottom electrode. A ferroelectric film is thinly stacked over the bottom electrode, and the first portion of the top electrode formed over and conformal to the ferroelectric film. A void that is left between sidewalls of the first portion of the electrode over the ferroelectric film is then filled with fill material for a fill layer. The fill material of the fill layer is then planarized to be level with and expose an upper surface of the first portion of the top electrode. A second portion of the top electrode is then formed over the fill layer and in contact with the exposed, e.g. peripheral regions of the first portion of the electrode. The fill material of the fill layer may be formed of polysilicon, silicon oxide or other material such as another metal. Additionally, the fill layer may be formed of a fill material that has a superior gap fill capability or of a material that has a low stress relationship with respect to the capacitor's top metal.
摘要:
Capacitors and methods of fabricating high dielectric capacitors which do not create a step difference where the high dielectric material is formed are provided. These methods include forming a first electrode layer on an integrated circuit device substrate and a layer of high dielectric material on the first electrode layer opposite the integrated circuit device substrate. A second electrode layer is formed on the layer of high dielectric material opposite the first electrode layer. The first electrode layer, the high dielectric layer and the second electrode layer are patterned to form a capacitor cell unit having a sidewall which extends from the first electrode beyond the layer of high dielectric material and to the second electrode layer. An insulating spacer is formed on the sidewall of the capacitor cell unit extending from the first electrode layer to the second electrode layer.

A method of forming a phase change material layer pattern includes forming a phase change material layer partially filling an opening through an insulating interlayer. A plasma treatment process is performed on the phase change material layer to remove an oxide layer on a surface of the phase change material layer. A heat treatment process is performed on the phase change material layer to remove a void or a seam in the phase change material layer, sufficiently filling the opening.
