Abstract:
1. A semiconductor device, comprising: a wiring substrate; a plurality of semiconductor chips, in each of which a field-effect transistor is built, each of said semiconductor chips being fixed over a metallized layer provided over a main surface of said wiring substrate with a fusion bonding material therebetween; and a conductive wire for electrically connecting each of the gate electrode and the drain electrode of said semiconductor chip to a bonding pad formed over the main surface of said wiring substrate, wherein each of said plurality of field-effect transistors is connected to another in order serially so as to configure each of a plurality of amplification stages of a multistage amplifier unit, and wherein at least in one of said plurality of transistors, the drain wire for connecting said drain electrode to said bonding pad is set shorter than the gate wire for connecting said gate electrode to said bonding pad.
