Abstract: Various embodiments generally relate to a power distribution network and a semiconductor device, which may include: a plurality of chip pads; a first distribution layer in which a plurality of first conductive lines having rectangular shapes of different sizes, respectively, are disposed; a second distribution layer in which a plurality of second conductive lines including a central cross-shaped conductive line and L-shaped conductive lines open toward respective corners of the second distribution layer are disposed; and a redistribution layer electrically coupling chip pads to which power is applied among the plurality of chip pads and the first conductive lines of the first distribution layer.

Abstract: Disclosed herein is a wear detection device for a brake pad of a disc brake, in which the disc brake includes a pair of brake pads that squeez a disc rotating together with a wheel of a vehicle at both sides of the disc, and pad plates to which the brake pads are attached. The wear detection device includes a sensor unit having a neck installed on the pad plate, a head extending from the neck to the brake pad, and a leg extending from the neck at a side opposite to the head in one body, an elastic clip configured to fix the neck to the pad plate, a cable connected to the sensor unit, and a connector configured to fix the sensor unit and the cable to the disc brake.
