Abstract
A semiconductor device having sufficiently high heat dissipation performance while inhibiting an increase in the area of a chip is provided. In semiconductor device, a plurality of HBTsand a plurality of diodesare one-dimensionally and alternately arranged on semiconductor substrate. Anode electrodeof diodeis connected to emitter electrodeof HBTvia common emitter wiring. Diodeworks as heat dissipating elements dissipating to semiconductor substratethe heat transmitted through common emitter wiringfrom emitter electrode, and also works as a protection diode connected in parallel between an emitter and a collector of HBT
