    摘要: A nonvolatile memory device includes a semiconductor substrate, a device isolation film, a tunnel insulation film, a plurality of floating gates, an inter-gate dielectric film, and a control gate pattern. Trenches are formed in the substrate that define active regions therebetween. The device isolation film is in the trenches in the substrate. The tunnel insulation film is on the active regions of the substrate. The plurality of floating gates are each on the tunnel insulation film over the active regions of the substrate. The inter-gate dielectric film extends across the floating gates and the device isolation film. The control gate pattern is on the inter-gate dielectric film and extends across the floating gates. A central region of the device isolation film in the trenches has an upper major surface that is recessed below an upper major surface of a surrounding region of the device isolation film in the trenches. An edge of the recessed central region of the device isolation film is aligned with a sidewall of an adjacent one of the floating gates.

    摘要: Non-volatile memory devices include a tunnel insulating layer on a channel region of a substrate, a charge-trapping layer pattern on the tunnel insulating layer and a first blocking layer pattern on the charge-trapping layer pattern. Second blocking layer patterns are on the tunnel insulating layer proximate sidewalls of the charge-trapping layer pattern. The second blocking layer patterns are configured to limit lateral diffusion of electrons trapped in the charge-trapping layer pattern. A gate electrode is on the first blocking layer pattern. The second blocking layer patterns may prevent lateral diffusion of the electrons trapped in the charge-trapping layer pattern.

    摘要: Methods of forming a contact structure in a semiconductor device include providing a semiconductor substrate including active regions and word lines crossing the active regions. A first interlayer dielectric layer is formed on the semiconductor substrate. Direct contact plugs are formed extending through the first interlayer dielectric layer to contact selected ones of the active regions. Bit line structures are formed on the first interlayer dielectric layer and crossing the word lines that are coupled to the selected ones of the active regions by the direct contact plugs. A second interlayer dielectric layer is formed on the semiconductor substrate including the bit line structures. Barrier patterns are formed extending in parallel with bit line structures and into the second interlayer dielectric layer. Mask patterns are formed overlying an entirety of top surfaces of the direct contact plugs on the second interlayer dielectric layer and the bit line structures. The second and first interlayer dielectric layers are etched using the mask patterns, the barrier patterns and the bit line structures as an etching mask to form buried contact holes and buried contact plugs are formed in the buried contact holes.

    摘要: A virtual measuring device and a method for measuring the deposition thickness of amorphous silicon being deposited on a substrate is disclosed, where the method of measuring the deposition thickness of amorphous silicon includes predicting and adapting operations. In the predicting operation, during a process of depositing the amorphous silicon to a substrate, the deposition thickness is predicted by multiplying a predicted deposition speed to a deposition time by using a prediction model expressing a relationship between a deposition speed and a plurality of process factors that are correlated with the deposition speed obtained from the deposition thickness and the deposition time, and the predicted deposition thickness is compared with the measured deposition thickness, so that the relationship between the plurality of process factors and the deposition speed in the prediction model is compensated according to the comparison difference.
