    摘要: Provided herein is a non-volatile semiconductor device that includes a tunnel insulation layer pattern formed on a semiconductor substrate, a charge trapping layer pattern formed on the tunnel insulation layer pattern, a blocking dielectric layer pattern formed on the charge trapping layer pattern and a tantalum carbon nitride layer pattern formed on the blocking dielectric layer pattern. The tantalum carbon nitride layer pattern may be formed by a CVD process using a source gas including a tantalum metal complex, wherein one or more of ligands of the tantalum metal complex include nitrogen and carbon. Since the non-volatile semiconductor device includes the tantalum carbon nitride layer pattern as an electrode, the non-volatile semiconductor device according to embodiments of the invention may have improved response speed and require relatively low driving voltage.

    摘要: A semiconductor device includes a gate structure on a channel region of a semiconductor substrate adjacent to a source/drain region therein and a surface insulation layer directly on the source/drain region of the substrate adjacent to the gate structure. The device further includes a spacer on a sidewall of the gate structure adjacent to the source/drain region. A portion of the surface insulation layer adjacent the gate structure is sandwiched between the substrate and the spacer. An interface between the surface insulation layer and the source/drain region includes a plurality of interfacial states. Portions of the source/drain region immediately adjacent the interface define a carrier accumulation layer having a greater carrier concentration than other portions thereof. The carrier accumulation layer extends along the interface under the spacer. Related methods are also discussed.

    摘要: Methods of fabricating semiconductor devices include forming a transistor on and/or in a semiconductor substrate, wherein the transistor includes a source/drain region and a gate pattern disposed on a channel region adjacent the source/drain region. An insulating layer is formed on the transistor and patterned to expose the source/drain region. A semiconductor source layer is formed on the exposed source/drain region and on an adjacent portion of the insulating layer. A metal source layer is formed on the semiconductor source layer.

    摘要: In a fin field effect transistor (FET), an active pattern protrudes in a vertical direction from a substrate and extends across the substrate in a first horizontal direction. A first silicon nitride pattern is formed on the active pattern, and a first oxide pattern and a second silicon nitride pattern are sequentially formed on the substrate and on a sidewall of a lower portion of the active pattern. A device isolation layer is formed on the second silicon nitride pattern, and a top surface of the device isolation layer is coplanar with top surfaces of the oxide pattern and the second silicon nitride pattern. A buffer pattern having an etching selectivity with respect to the second silicon nitride pattern is formed between the first oxide pattern and the second silicon nitride pattern. Internal stresses that can be generated in sidewalls of the active pattern are sufficiently released and an original shape of the first silicon nitride pattern remains unchanged, thereby improving electrical characteristics of the fin FET.

    摘要: In a method of manufacturing a stacked semiconductor device, a seed layer including impurity regions may be prepared. A first insulation interlayer pattern having a first opening may be formed on the seed layer. A first SEG process may be carried out to form a first plug partially filling the first opening. A second SEG process may be performed to form a second plug filling the first opening. A third SEG process may be carried out to form a first channel layer on the first insulation interlayer pattern. A second insulation interlayer may be formed on the first channel layer. The second insulation interlayer, the first channel layer and the second plug arranged on the first plug may be removed to expose the first plug. The first plug may be removed to form a serial opening. The serial opening may be filled with a metal wiring.
