    摘要: The present invention is related to a method for forming vertical conductive structures by electroplating. Specifically, a template structure is first formed, which includes a substrate, a discrete metal contact pad located on the substrate surface, an inter-level dielectric (ILD) layer over both the discrete metal contact pad and the substrate, and a metal via structure extending through the ILD layer onto the discrete metal contact pad. Next, a vertical via is formed in the template structure, which extends through the ILD layer onto the discrete metal contact pad. A vertical conductive structure is then formed in the vertical via by electroplating, which is conducted by applying an electroplating current to the discrete metal contact pad through the metal via structure. Preferably, the template structure comprises multiple discrete metal contact pads, multiple metal via structures, and multiple vertical vias for formation of multiple vertical conductive structures.

    摘要: A Vertical Field Effect Transistor (VFET) formed on a substrate, with a conductive bottom electrode formed thereon. A bottom dielectric spacer layer and a gate dielectric layer surrounded by a gate electrode are formed thereabove. Thereabove is an upper spacer layer. A pore extends therethrough between the electrodes. A columnar Vertical Semiconductor Nanowire (VSN) fills the pore and between the top and bottom electrodes. An FET channel is formed in a central region of the VSN between doped source and drain regions at opposite ends of the VSN. The gate dielectric structure, that is formed on an exterior surface of the VSN above the bottom dielectric spacer layer, separates the VSN from the gate electrode.
