Abstract
A semiconductor device includes a board base having through-holes filled with a filling core, and an additive layer provided on an upper surface of the board base as well as an upper surface of the filling core wherein the additive layer includes a wiring pattern having one or more paths. The semiconductor device further includes a semiconductor chip fixed on an upper surface of the additive layer, and nodes provided on a lower surface of the board base, wherein the one or more paths are laid out without a passage restriction posed by the through-holes, and are used for electrically connecting the semiconductor chip and the nodes.
