    Abstract: Semiconductor devices are provided including a first trench in a semiconductor substrate; a first insulating film in the first trench; a first conductive film on the first insulating film, the first conductive film having upper and lower portions and filling at least a portion of the first trench; and a first work function adjustment film having first and second portions, a first lower work function adjustment film portion and a first upper work function adjustment portion. The first lower work function adjustment film portion overlaps the lower portion of the first conductive film and the first upper work function adjustment film portion overlaps the upper portion of the first conductive film between the first insulating film and the first conductive film.

    Abstract: A method of manufacturing a semiconductor device includes forming a via including a first conductive material on an inner wall of a trench on a substrate. The method further includes forming a first insulating interlayer on the substrate. The first insulating interlayer covers the via and partially fills the trench, and the first insulating interlayer has a non-flat upper surface. The method further includes forming a polishing stop layer on the first insulating interlayer, forming a second insulating interlayer on the polishing stop layer, in which the second insulating interlayer fills a remaining portion of the trench, planarizing the second insulating interlayer until the polishing stop layer is exposed, and etching the polishing stop layer and the first and second insulating interlayers using a dry etching process until remaining portions of the polishing stop layer except for a portion of the polishing stop layer in the trench are removed.

    Abstract: In a method of operating a nonvolatile memory device, a first sub-block to be erased is selected in a first memory block including the first sub-block and a second sub-block adjacent to the first sub-block, in response to a erase command and an address. The first sub-block includes memory cells connected to a plurality of word-lines including at least one boundary word-line adjacent to the second sub-block and internal word-lines other than the at least one boundary word-line. An erase voltage is applied to a substrate in which the first memory block is formed. Based on a voltage level of the erase voltage applied to the substrate, applying, a first erase bias condition to the at least one boundary word-line and a second erase bias condition different from the first erase bias condition to the internal word-lines during an erase operation being performed on the first sub-block.

    Abstract: A semiconductor device includes a semiconductor substrate having an active region. A gate trench is disposed to cross the active region. First and second source/drain regions are disposed in the active region at both sides of the gate trench. A gate electrode is disposed in the gate trench. A gate dielectric layer is disposed between the gate electrode and the active region. A stress pattern is disposed on the gate electrode and in the gate trench. The stress pattern has a lower residual stress than silicon nitride.
