    • PROBLEM TO BE SOLVED: To provide a semiconductor device in which a semiconductor chip 3 is solder bonded to a lead frame 4, and which inhibits damages caused by cracks generated in a solder layer.SOLUTION: A semiconductor device 2 disclosed in the present specification comprises: the lead frame 4; the semiconductor chip 3 solder bonded to the lead frame 4; and a metal rod 6 buried in the solder layer. The metal rod 6 extends in the solder layer along one side of the semiconductor chip 3 when viewed from a direction perpendicular to the lead frame 4, and is arranged in a manner such that a part overlaps the semiconductor chip 3 and the rest does not overlap the semiconductor chip 3. Further, the metal rod 6 has an outline of a cross section along a width direction of the metal rod 6 from an end of the semiconductor chip side to an end on the lead frame side and on a center side of the semiconductor chip, which is curved so as to project toward the center side of the semiconductor chip.
    • 要解决的问题:提供半导体芯片3焊接到引线框架4并且抑制由焊料层中产生的裂纹引起的损伤的半导体器件。解决方案:本说明书中公开的半导体器件2包括 引线架4; 焊接到引线框4的半导体芯片3焊料; 以及埋入焊料层中的金属棒6。 当从垂直于引线框架4的方向观察时,金属棒6沿着半导体芯片3的一侧在焊料层中延伸,并且被布置成使得部件与半导体芯片3重叠并且其余部分不重叠 半导体芯片3.此外,金属棒6具有从半导体芯片侧的端部到引线框架侧的端部以及金属棒6的中心侧的金属棒6的宽度方向的截面的轮廓 半导体芯片,其弯曲成朝向半导体芯片的中心侧突出。
