    • A semiconductor device includes: a semiconductor chip connected onto a surface of a printed wiring board in a flip-chip connection; a dam for preventing an outflow of underfill, the dam being provided on the surface of the printed wiring board and surrounding an entire circumference of the semiconductor chip; an external connection terminal for the semiconductor chip, the external connection terminal being provided on the surface of the printed wiring board and arranged outside the dam; a solder resist layer covering the surface of the printed wiring board except for portions for the flip-chip connection and the external connection terminal arrangement; and at least one recess portion being provided in the solder resist layer and within a region between a corner portion of the semiconductor chip and a corner portion of the dam being opposed to the corner portion of the semiconductor chip.
    • 半导体器件包括:以倒装芯片连接连接到印刷线路板的表面上的半导体芯片; 用于防止底部填充物流出的堤坝,坝体设置在印刷线路板的表面上并围绕半导体芯片的整个周边; 用于半导体芯片的外部连接端子,外部连接端子设置在印刷线路板的表面上,并布置在坝外; 覆盖印刷电路板的表面的阻焊层,除了用于倒装芯片连接的部分和外部连接端子装置; 并且至少一个凹部设置在阻焊层中,并且在半导体芯片的角部与坝的角部之间的区域内,与半导体芯片的角部相对。
