Abstract: In semiconductor device 10 under this invention, bonding pads 20 are lined up in a staggered pattern on the main surface of semiconductor chip 14 which is mounted on insulated substrate 12. Multiple stud bumps are stacked on top of the pads 20a which are located on the inner rows, and these stud bumps comprise stud bump stack 28. Conductive wire 22 connects the lands 18 on the insulated substrate with the corresponding bonding pads 20. The wire is formed with its beginning at the land and its end at the bonding pad. Via the stud bump stacks 28, the ends of conductive wire 22a on the inner pads are in a higher position than the ends of conductive wires 22b on the outer pads, so that the problem of neighboring conductive wires coming into contact does not occur.

Semiconductor chip 100 has top surface 112, where an electronic circuit is formed, and a bottom surface 114 adhered to insulating substrate 102. The bottom surface 114 is formed smaller than top surface 112. By forming bottom surface 114 smaller than top surface 112, the amount of the fillet spread out around semiconductor chip 100 can be reduced.

Further, the device has a protective plastic film (polyimide, epoxy resin, or silicone) of controlled and uniform thickness (20 to 60 &mgr;m) selectively attached to the passive surface. The film is suitable to absorb light of visible and ultraviolet wavelengths, to remain insensitive to moisture absorption, and to exert thermomechanical stress on the chip such that this stress at least partially neutralizes the stress exerted by an outside part after chip assembly.
