Abstract: PURPOSE: A flip chip package is provided to a short between the bumps in spite of decreasing a thickness of a package by applying a substrate structure having a groove at a point contacting to the bump of a semiconductor. CONSTITUTION: The bump(22) of a semiconductor chip(21) is inserted into the groove(31) of a substrate(30) by penetrating an anisotropic adhesive polymer layer having an adhesive layer(36a) and a conductive polymer layer(36b).

Thus, the polymer coated on a surface of a conductive particle(37) is melt and the arranged conductive particle conducts between the bump and the pad. An inclined sidewall(31a) of the groove separates the conductive particle layer under the bump from the polymer layer including the conductive particle.
