Abstract
For example, a semiconductor device includes one or more first subcontacts electrically conducted to a substrate. At least one of the one or more first subcontacts is formed in an element arrangement region, and has a lower impedance than the substrate. Preferably, at least one of the one or more first subcontacts is adjacent to a circuit element formed in the element arrangement region. Preferably, on the substrate, which is of a first conductivity type, an epilayer of a second conductivity type is formed, and the one or more first subcontacts include a first line having a lower impedance than the substrate, and a semiconductor region of the first conductivity type penetrating through the epilayer to electrically conduct the first line and the substrate to each other.
