Patent ID: 7989939

Claim:
A semiconductor package comprising: a first package substrate and a second package substrate; a bonding wire electrically connecting the first package substrate and the second package substrate to each other, wherein the second package substrate comprises a through hole penetrating a portion of the second package substrate so as to expose a portion of the first package substrate, thereby providing a space where the bonding wire is disposed; and an insulating layer which adheres the first package substrate and the second package substrate to each other and covers a portion of the bonding wire, wherein the insulating layer comprises: an adhesion layer which is disposed between the first package substrate and the second package substrate to adhere the first package substrate and the second package substrate to each other; and a wire fixing layer which includes a portion of material which is part of the adhesion layer and which extends from the adhesion layer and into the through hole to occupy the through hole and cover the portion of the bonding wire.
