Semiconductor device

一种网格焊球阵列型半导体封装件，用粘接材料将半导体芯片安装在柔性膜衬底的表面上，在上述衬底的背面将多个突块电极排列成矩阵，并用树脂密封半导体芯片。具体地说，制作一个绝缘层来覆盖制作在衬底表面上的导体层图形，并用粘接材料将半导体芯片安装在绝缘层上。上述绝缘层在上述半导体芯片下方的区域中被分割成多个互不相连的部分，利用这种被分割的绝缘层，防止了上述半导体芯片与上述导体层图形之间的短路，并抑制了含有上述柔性膜的衬底的变形。 In a method of forming a ball grid array type semiconductor package, a semiconductor chip is mounted through an adhesive material on a surface of a flexible film substrate. Plural bump electrodes are arranged in an array on the opposite side of said substrate and the semiconductor chip is sealed by a resin. In this regard, an insulation layer is formed to cover an electric conductor layer pattern formed on the surface of the substrate, and the semiconductor chip is mounted through an adhesive material on the insulation layer. The insulation layer is divided into a plural number of parts that are mutually discontinuous in the area under the semiconductor chip. By this divided insulation layer, a short circuit between the semiconductor chip and the electric conductor layer pattern is prevented and a deformation of the substrate that comprises the flexible films is suppressed.
