Abstract:
A plastic-encapsulated semiconductor device comprising:(a) an IC chip having a surface having (i) a top portion on which a first plurality of bonding pads are provided, and (ii) a bottom portion on which a second plurality of bonding pads are provided;said first plurality of bonding pads being arranged in a central area of the top portion of said surface, and said second plurality of bonding pads being arranged in a peripheral area of the bottom portion of said surface;(b) lead fingers whose inner ends are fixed to said surface of said IC chip;at least one of said lead fingers serving as a part of a power/ground line for said IC chip;(c) a bus-bar mechanically and electrically connected to said at least one of said lead fingers serving as a part of said power/ground line;said bus-bar extending over said surface of said IC chip;(d) bonding wires for electrically connecting said inner ends of said lead fingers and said bus-bar to corresponding ones of said first and second pluralities of bonding pads; and(e) a plastic package for encapsulating said IC chip, inner portions of said lead fingers, said bus-bar, and said bonding wires, while protruding outer portions of said lead fingers from said package;said bus-bar being formed to extend over said central area of said surface of said IC chip such that said bonding wires electrically connecting said first plurality of bonding pads to corresponding ones of said lead fingers do not extend over said bus-bar.
