BONDING OF SEMICONDUCTOR POWER DEVICES

摘要

There is disclosed herein a semiconductor power device assembly 80 which may be bonded to a circuit board without wirebonding. The device comprises: (a) a bare die semiconductor power device 10 having a top surface 12 and a bottom surface 14; (b) at least one metallic die bump 20 attached to the top surface 12 of the power device 10; (c) a metallic mounting tab 40 having a first portion 42 attached to the bottom surface of the power device; a second portion 44 oriented above, outward from, and generally parallel with the first portion and having a top surface 46 thereon; and a third portion 48 connecting the first portion 42 with the second portion 44; and (d) a metallic mounting tab bump 50 attached to the top surface 46 of the second portion 44. The top surface 46 of the second portion 44 is oriented generally coplanar with the top surface 12 of the power device 10.
