Abstract:
A semiconductor device comprising:a semiconductor chip having a square surface; a wiring substrate having a main surface thereof used for mounting said semiconductor chip; a first electrode formed on a first area of a main surface of said semiconductor chip and placed at a location in close proximity to a side of said semiconductor chip extending in a first direction; first amplifying means formed on said first area of said main surface of said semiconductor chip and provided with an input unit electrically connected to said first electrode; a second electrode formed on a second area of said main surface of said semiconductor chip and placed at a location in close proximity to said side of said semiconductor chip; second amplifying means formed on said second area of said main surface of said semiconductor chip and provided with an output unit electrically connected to said second electrode; a third electrode formed on a third area between said first and second areas of said main surface of said semiconductor chip; a fourth electrode formed on said main surface of said wiring substrate to face said side of said semiconductor chip and electrically connected to said first electrode by a first wire; a fifth electrode formed on said main surface of said wiring substrate to face said side of said semiconductor chip and electrically connected to said second electrode by a second wire; and a sixth electrode formed on said main surface of said wiring substrate to face said side of said semiconductor chip and electrically connected to said third electrode by a third wire with an electric potential thereof fixed at a reference level, wherein said first to third wires extend in a second direction which is substantially perpendicular to said first direction, wherein said sixth electrode is placed at a location farther from said side of said semiconductor chip than said fourth and fifth electrodes in said second direction.
