Abstract: An n-type metal oxide semiconductor transistor includes a gate structure, two source/drain regions, two amorphous portions and a silicide. The gate structure is disposed on a substrate. The two source/drain regions are disposed in the substrate and respectively located at two sides of the gate structure, wherein at least one of the source/drain regions is formed with a dislocation. The two amorphous portions are respectively disposed in the two source/drain regions. The silicide is disposed on the two source/drain regions, wherein at least one portion of the silicide overlaps the two amorphous portions.

Abstract: A warning device includes a supporting unit, a plurality of supporting frames pivotally connected to the supporting unit, and a warning unit. The warning unit is mounted to the supporting frames and configured to be driven by a slide seat of the supporting unit, via the supporting frames, to be in an expanded state when a distal end portion of each of the supporting frames is at an expanded position, and to be in a collapsed state when the distal end portion of each of the supporting frames is at a collapsed position. The warning unit includes at least one warning member made of a flexible material, and defining a hollow region when the warning unit is in the expanded state.
