    摘要: A nanowire device of the present description may be produced with the incorporation of at least one underlayer etch stop formed during the fabrication of at least one nanowire transistor in order to assist in protecting source structures and/or drain structures from damage that may result from fabrication processes. The underlayer etch stop may prevent damage to the source structures andor drain the structures, when the material used in the fabrication of the source structures andor the drain structures is susceptible to being etched by the processes used in the removal of the sacrificial materials, i.e. low selectively to the source structure and/or the drain structure materials, such that potential shorting between the transistor gate electrodes and contacts formed for the source structures andor the drain structures may be prevented.

    摘要: A nanowire device of the present description may include a highly doped underlayer formed between at least one nanowire transistor and the microelectronic substrate on which the nanowire transistors are formed, wherein the highly doped underlayer may reduce or substantially eliminate leakage and high gate capacitance which can occur at a bottom portion of a gate structure of the nanowire transistors. As the formation of the highly doped underlayer may result in gate inducted drain leakage at an interface between source structures and drain structures of the nanowire transistors, a thin layer of undoped or low doped material may be formed between the highly doped underlayer and the nanowire transistors.
