    摘要: A method of fabricating a semiconductor device, can be provided by forming gate structures for transistors on a semiconductor substrate in a cell region and in a peripheral circuit region. An offset spacer can be formed including a first material on the gate structures. A first ion implantation can be done using the gate structures and the offset spacer as an ion implantation mask to form source/drain regions. A material layer can be formed including a second material on the semiconductor substrate and on the gate structures. A material layer can be formed of a third material, having an etch selectivity with respect to the second material, on the material layer of the second material. An etch-back can be performed the material layer comprising the third material in the cell region and in the peripheral region, to simultaneously expose the source/drains region in the peripheral region and not expose the source/drain regions in the cell region.

    摘要: A method of forming a gate structure can be provided by forming a tunnel insulation layer on a substrate and forming a floating gate on the tunnel insulation layer. A dielectric layer pattern can be on the floating gate and a control gate can be formed on the dielectric layer pattern, which can be provided by forming a first conductive layer pattern on the dielectric layer pattern. A metal ohmic layer pattern can be formed on the first conductive layer pattern. A diffusion preventing layer pattern can be formed on the metal ohmic layer pattern. An amorphous layer pattern can be formed on the diffusion preventing layer pattern forming a second conductive layer pattern on the amorphous layer pattern. The floating gate can be further formed by forming an additional first conductive layer pattern on the tunnel insulation layer. An additional metal ohmic layer pattern can be formed on the additional first conductive layer pattern. An additional diffusion preventing layer can be formed pattern on the additional metal ohmic layer pattern. An additional amorphous layer pattern can be formed on the additional diffusion preventing layer pattern and an additional second conductive layer pattern can be formed on the additional amorphous layer pattern.

    摘要: In a method of forming an integrated circuit device, an opening is formed extending through a first and a second insulating layers and through a semiconductor layer therebetween to a surface of a substrate. The opening includes a recess in a sidewall thereof between the first and second insulating layers adjacent the semiconductor layer. A conductive plug is formed on the sidewall of the opening and on the surface of the substrate and laterally extending into the recess between the first and second insulating layers to contact the semiconductor layer. The semiconductor layer may be selectively etched at the sidewall without substantially etching the first and second insulating layers at the sidewall of the opening to form the recess between the first and second insulating layers. Related devices are also discussed.
