Abstract: A semiconductor device includes a logic circuit region having at least one core device and at least one input/output (I/O) device. The at least one core device has a first accumulative antenna ratio, and the at least one I/O device has a second accumulative antenna ratio. The first accumulative antenna ratio is greater than the second accumulative antenna ratio.

Abstract: A clamping device for a trailer truck includes a connecting member, a positioning member mounted on the connecting member, a driving member pivotally connected with the connecting member, and a clamping member pivotally connected with the driving member. The connecting member is provided with a threaded rod. The positioning member is screwed onto the threaded rod. The clamping device is mounted on a crossbar of a trailer truck. The crossbar of the trailer truck is clamped between the connecting member and the clamping member by driving the driving member. When the crossbar of the trailer truck is unlocked from the clamping device, the clamping device is movable on the crossbar of the trailer truck.

Abstract: An adjustable clamping device includes a connecting member mounted on a crossbar of a trailer truck, a positioning member mounted on a top face of the connecting member, a rotation member mounted on a bottom face of the connecting member and provided with a threaded rod extending into the connecting member, and a pressing member mounted on the threaded rod and received in the connecting member. The bottom face of the connecting member is provided with a screw hole. The threaded rod of the rotation member is screwed through the screw hole into the connecting member. Thus, the pressing member is moved upward or downward by revolving the rotation member to adjust the distance between the top face of the connecting member and the pressing member.
