    摘要： A memory cell in an integrated circuit is fabricated in part by forming a lower electrode feature, an island, a sacrificial feature, a gate feature, and a phase change feature. The island is formed on the lower electrode feature and has one or more sidewalls. It comprises a lower doped feature, a middle doped feature formed above the lower doped feature, and an upper doped feature formed above the middle doped feature. The sacrificial feature is formed above the island, while the gate feature is formed along each sidewall of the island. The gate feature overlies at least a portion of the middle doped feature of the island and is operative to control an electrical resistance therein. Finally, the phase feature is formed above the island at least in part by replacing at least a portion of the sacrificial feature with a phase change material. The phase change material is operative to switch between lower and higher electrical resistance states in response to an application of an electrical signal.

    摘要： Methods of making vertical profile FinFET gate electrodes via plating upon a thin gate dielectric are disclosed. In one embodiment, a method for forming a transistor, comprises: providing a semiconductor topography comprising a semiconductor substrate and a semiconductor fin structure extending above the substrate; forming a gate dielectric across exposed surfaces of the semiconductor topography; patterning a mask upon the semiconductor topography such that only a select portion of the gate dielectric is exposed that defines where a gate electrode is to be formed; and plating a metallic material upon the select portion of the gate dielectric to form a gate electrode across a portion of the fin structure.

    摘要： A semiconductor fabrication method. The method includes providing a semiconductor structure which includes (i) a semiconductor layer, (ii) a gate dielectric layer on the semiconductor layer, and (iii) a gate electrode region on the gate dielectric layer. The gate dielectric layer is sandwiched between and electrically insulates the semiconductor layer and the gate electrode region. The semiconductor layer and the gate dielectric layer share a common interfacing surface which defines a reference direction perpendicular to the common interfacing surface and pointing from the semiconductor layer to the gate dielectric layer. Next, a resist layer is formed on the gate dielectric layer and the gate electrode region. Next, a cap portion of the resist layer directly above the gate electrode region in the reference direction is removed without removing any portion of the resist layer not directly above the gate electrode region in the reference direction.
