A power device is formed by a thyristor and by a MOSFET transistor, series-connected between a first and a second current-conduction terminal. A support structure is connected to and configured for supporting the platform structure. On the other hand, a Si-Ge layer is used to react with the conductive layer deposited thereon after for forming a Ge-salicide layer. It is obtained by means of a selectivation treatment of a porous carbon-free inorganic membrane using a hydrocarbon feed.
