摘要:
A solder resist and a central pad to which a central Au bump provided on a semiconductor chip is flip-chip bonded are formed on a substrate main body. In a flip-chip mounting substrate where an underfill resin is provided after the semiconductor chip is mounted, a central opening portion for exposing the central pad is formed in the solder resist, and also, an edge portion forming the central opening portion of the solder resist is partially overlapped with the outer peripheral portion of the central pad.
