Abstract
The transistor includes a semiconductor body having a surface on which are disposed metallic connection contact areas, including means for protection from overloads. At least one of the metallic area comprises a material, such as Al, susceptible to forming a eutectic with the substrate, which is made, for example, of Si. The metallic area is formed from an alloy of the material, such as the Al-Si eutectic, having a melting point whose temperature is lower than the formation temperature of the Al-Si eutectic and higher than the temperature of soldering the semiconductor body on a support.
