Abstract
A semiconductor component that could be a power transistor type of component comprises mesa-structured elementary bipolar transistors. This component has a thick, metal heat sink of which a part (PI) takes the form of a bridge and a part is in contact with the substrate. The legs of the bridge lie on the entire unit constituted by the mesas. The heat sink made on the front face of the substrate may be connected to the rear face of the substrate comprising a ground plate. The discharging of the heat is thus appreciably fostered.
