    Abstract: A semiconductor device includes a first active pattern on a substrate. The first active pattern includes a pair of first source/drain patterns and a first channel pattern therebetween. A gate electrode is disposed on the first channel pattern, and a first gate spacer is disposed on a side surface of the gate electrode. The first gate spacer includes a first spacer and a second spacer. A top surface of the first spacer is lower than a top surface of the second spacer. A first blocking pattern is disposed on the first spacer, and a gate contact is coupled to the gate electrode. The first blocking pattern is interposed between the gate contact and the second spacer.

    Abstract: A semiconductor memory device includes a substrate having a first region and a second region. A first gate electrode layer is on the first region and includes a first conductive layer including a first plurality of layers, and includes a first upper conductive layer on the first conductive layer. A second gate electrode layer is on the second region and includes a second conductive layer including a second plurality of layers, and includes a second upper conductive layer on the second conductive layer. At least one of the first plurality of layers includes titanium oxynitride (TiON). A first transistor including the first gate electrode layer and a second transistor including the second gate electrode layer are metal oxide semiconductor field effect transistors (MOSFETs) having the same channel conductivity type, and a threshold voltage of the first transistor is smaller than a threshold voltage of the second transistor.
