Semiconductor device having a ball grid array and a fabrication process thereof |
摘要 |
A semiconductor device has a resin package layer on a principal surface of a semiconductor chip, on which a number of bump electrodes are formed, wherein the semiconductor device has a chamfer surface or a stepped surface on a top edge part such that the external shock or stress applied to such an edge part is dissipated by the chamfer surface of the stepped surface.
