Abstract
A wiring substrate includes a first wiring substrate, a first insulation layer covering the first wiring layer, a second insulation layer stacked on the first insulation layer, and a cavity extending through the second insulation layer and exposing a portion of the upper surface of the first insulation layer. The cavity includes an opening, which is defined by an upper portion of a stepped inner wall surface of the second insulation layer, and a recess, which is defined by a lower portion of the stepped inner wall surface that contacts the upper surface of the first insulation layer. The recess is wider than the opening. An electronic component is mounted on the upper surface of the first insulation layer. The opening and the recess are filled with a third insulation layer that covers the electronic component and the second insulation layer.
