    Abstract: A semiconductor device includes a substrate with first and second areas, a first trench in the first area, and first and second PMOS transistors in the first area and the second area, respectively. The first transistor includes a first gate insulating layer, a first TiN layer on and contacting the first gate insulating layer, and a first gate electrode on and contacting the first TiN layer. The second transistor includes a second gate insulating layer, a second TiN layer on and contacting the second gate insulating layer, and a first TiAlC layer on and contacting the second TiN layer. The first gate insulating layer, the first TiN layer, and the first gate electrode are within the first trench. The first gate electrode does not include aluminum. A threshold voltage of the first transistor is smaller than a threshold voltage of the second transistor.

    Abstract: A semiconductor device includes a first active pattern extending lengthwise along a first direction and a second active pattern extending lengthwise along the first direction and spaced apart from the first active pattern in the first direction. The device also includes a field insulating film between the first active pattern and the second active pattern. An upper surface of the field insulating film is lower than or coplanar with upper surfaces of the first and second active patterns. The device further includes an element isolation structure in an isolation trench in the first active pattern and the field insulating film. An upper surface of the element isolation structure is higher than the upper surfaces of the first and second active patterns.
