Abstract: A layout method and a semiconductor device are disclosed. The layout method includes: generating a design layout by placing a cell, wherein the cell includes: a first conductive segment overlapping a source/drain region and disposed immediately adjacent to a first power rail, wherein the first conductive segment has a length substantially equal to a cell length; a second conductive segment; and a third conductive segment between the first and second conductive segments. The layout method further includes: providing a fourth conductive segment and a fifth conductive segment to the design layout, wherein the fourth and fifth conductive segments are aligned in a first direction.

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.
