Abstract:
To improve signal transmission characteristics of a high frequency signal of 80 GHz or higher. A semiconductor device includes a wiring board having a structure in which a signal via structure and a grounding via structure have mutually overlapping portions in plan view.

Claim (Index 11):
A semiconductor device comprising:\n a semiconductor chip; and a wiring board coupled to the semiconductor chip, wherein the wiring board includes: a signal via structure coupled to a signal line; and a grounding via structure coupled to a ground line, wherein the wiring board includes: a first build-up layer equipped with the semiconductor chip; a core layer positioned in a lower layer of the first build-up layer; and a second build-up layer positioned in a lower layer of the core layer, wherein the signal via structure includes: a surface land formed at a surface of the core layer; a signal through via coupled to the surface land and penetrating the core layer; and a back surface terminal electrically coupled to the signal through via and formed at a back surface of the second build-up layer, wherein the grounding via structure includes: a grounding surface pattern formed at the surface of the core layer; and a grounding through via coupled to the grounding surface pattern and penetrating the core layer, and wherein when in one cross-section parallel to the direction of thickness of the wiring board and obtained by cutting both the signal via structure and the grounding via structure, an angle formed by a line segment coupling a first end of the back surface terminal and a second end of the grounding surface pattern and a vertical line passing the first end is defined to be \u03d5, a relation of cos\u03d5\u22650.89 is established.
