Abstract: A semiconductor device includes a substrate and a gate structure. The gate structure is disposed on the substrate, and the gate structure includes a titanium nitride barrier layer a titanium aluminide layer, and a middle layer. The titanium aluminide layer is disposed on the titanium nitride barrier layer, and the middle layer is disposed between the titanium aluminide layer and the titanium nitride barrier layer. The middle layer is directly connected with the titanium aluminide layer and the titanium nitride barrier layer, and the middle layer includes titanium and nitrogen. A concentration of nitrogen in the middle layer is gradually decreased in a vertical direction towards an interface between the middle layer and the titanium aluminide layer.

Abstract: This invention provides an air disinfecting device for disinfecting or decontaminate air, which comprises a first metal plate and a second metal plate opposite to the first metal plate, a UVC LED mounted on the first metal plate, and a power supply providing power to the UVC LED. The second metal plate has an area large enough such that lights emitted from the UVC LED will be enclosed inside the air disinfection device.

Abstract: An electronic device includes a bottom plate, a heat pipe, a battery assembly, and a heat dissipation layer. The heat pipe is disposed along the bottom plate. The battery assembly is disposed on the bottom plate. The heat dissipation layer is disposed between the heat pipe and the bottom plate and extends between the battery assembly and the bottom plate.

Abstract: An engagement fan includes a fan base, a cover plate and a fan base plate. The fan base has an opening at the bottom surface thereof. The rim of the opening is disposed with at least one engagement slot and at least one restricting protrusion. The cover plate covers the fan base. The engagement protrusion engages to the corresponding engagement slot such that the fan base plate can be attached to the opening of the fan base.
