    摘要: A non-volatile memory device includes a field region that defines an active region in a semiconductor substrate, a floating gate pattern on the active region, a dielectric layer on the floating gate pattern and a control gate on the dielectric layer. The control gate includes a first conductive pattern that has a first composition that crystallizes in a first temperature range, and a second conductive pattern that has a second composition that is different from the first composition and that crystallizes in a second temperature range that is lower than the first temperature range, the first conductive pattern being between the dielectric layer and the second conductive pattern.

    摘要: According to example embodiments, a semiconductor device includes horizontal patterns stacked on a substrate. The horizontal patterns define an opening through the horizontal patterns. A first core pattern is in the opening. A second core pattern is in the opening on the first core pattern. A first active pattern is between the first core pattern and the horizontal patterns. A second active pattern containing a first element is between the second core pattern and the horizontal patterns. The second active pattern contains the first element at a higher concentration than a concentration of the first element in the second core pattern.

    摘要: In a method of manufacturing a semiconductor device, a polysilicon layer doped with impurities is formed on a front side and a backside of a substrate. An insulation layer is formed on the substrate having the polysilicon layer to cover the polysilicon layer on the backside of the substrate. The insulation layer on the front side of the substrate is partially etched to partially expose the front side of the substrate. An oxidation process using oxygen radicals is then carried out to form an oxide layer on the exposed front side of the substrate Thus, when the oxidation process is carried out, the insulation layer prevents impurities in the polysilicon layer on the backside of the substrate from being outgassed. As a result electrical characteristics of the transistor formed on the front side of the substrate may not be deteriorated.
