SEMICONDUCTOR ELEMENT-EMBEDDED WIRING SUBSTRATE
First Claim
1. A wiring substrate containing a semiconductor element, the wiring substrate comprising:
- a supporting substrate;
a semiconductor element provided on the supporting substrate;
a peripheral insulating layer provided on the supporting substrate and covering at least an outer circumferential side surface of the semiconductor element; and
upper surface-side wiring provided on the upper surface side of the wiring substrate,the semiconductor element comprising;
a semiconductor substrate;
a first wiring-structure layer comprising first wiring and a first insulating layer alternately formed on the semiconductor substrate; and
a second wiring-structure layer comprising second wiring and a second insulating layer alternately formed on the first wiring-structure layer,wherein the upper surface-side wiring comprises fan-out wiring led out from immediately above the semiconductor element to a peripheral region external to an outer edge of the semiconductor element, the fan-out wiring being electrically connected to the first wiring through the second wiring;
the thickness of the second wiring is greater than the thickness of the first wiring but less than the thickness of the upper surface-side wiring; and
the second insulating layer is formed of a resin material and greater in thickness than the first insulating layer.

Abstract
In a wiring substrate containing a semiconductor element, the wiring substrate includes a supporting substrate; a semiconductor element provided on the supporting substrate; a peripheral insulating layer covering at least an outer circumferential side surface of the semiconductor element; and upper surface-side wiring provided on the upper surface side of the wiring substrate. The semiconductor element includes a semiconductor substrate; a first wiring-structure layer including first wiring and a first insulating layer alternately formed on the semiconductor substrate; and a second wiring-structure layer including second wiring and a second insulating layer alternately formed on the first wiring-structure layer. The upper surface-side wiring includes fan-out wiring led out from immediately above the semiconductor element to a peripheral region external to an outer edge of the semiconductor element. The fan-out wiring is electrically connected to the first wiring through the second wiring. The second wiring is thicker than the first wiring but thinner than the upper surface-side wiring. The second insulating layer is formed of a resin material and is thicker than the first insulating layer.
