Abstract:
1. A method for manufacturing a semiconductor device comprising: a wiring substrate; a plurality of semiconductor chips, in each of which a transistor is built, each of said semiconductor chips being fixed over a metallized layer formed over a main surface of said wiring substrate with a fusion bonding material therebetween; and a conductive wire for electrically connecting an electrode for controlling said semiconductor chip and an electrode for outputting a signal to a bonding pad provided over said main surface of said wiring substrate, wherein each of said plurality of transistors is connected to another in order serially in a circuit manner so as to form a multistage amplifier unit of multiple configuration, wherein said method fixes said semiconductor chip one-sidedly so that at least in one of said plurality of transistors, a length of said wire for connecting said signal output electrode to said bonding pad becomes shorter than that of said wire for connecting said control electrode to said bonding pad.
