Abstract
A high-power semiconductive device having a conductive liquid for maintaining contact between the active semiconductive element and the associated current supply and feeding facilities is described. A resilient insulating ring disposed in contact with the periphery of the active semiconductive element is contacted on respectively opposite sides by a pair of heat-conductive tubes that serve as the current supply elements of the device. A pair of conductive plates disposed on opposite sides of the semiconductive element are secured to the sides of the heat-conductive tubes to close off a pair of mutually insulated chambers which are bounded on the other side by the terminal areas of the semiconductive element. The conductive liquid is disposed in each of the so-defined chambers to provide thermal and electrical contact between the heat-conductive tubes and the terminal areas of the semiconductive element.
