Patent ID: 11869863
Assignee: SHINKO ELECTRIC INDUSTRIES CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A semiconductor device comprising:
a substrate;
an adhesive layer formed on a lower surface of the substrate;
a semiconductor element adhered to a lower surface of the adhesive layer;
a through hole that extends through the substrate and the adhesive layer and exposes a first electrode arranged on an upper surface of the semiconductor element;
a via wiring formed in the through hole;
a wiring layer formed on an upper surface of the substrate and electrically connected to the first electrode through the via wiring; and
a protective insulation layer formed on the lower surface of the adhesive layer, wherein the protective insulation layer covers an entirety of all side surfaces of the semiconductor element and a peripheral part of a lower surface of the semiconductor element and exposes a central part of the lower surface of the semiconductor element,
wherein the protective insulation layer includes an opening that exposes a second electrode arranged on the lower surface of the semiconductor element, the semiconductor device further comprising:
a wiring substrate on which the semiconductor element is mounted; and
a connecting member that is formed in the opening of the protective insulation layer and electrically connects the second electrode to a wiring pattern of the wiring substrate.
