    摘要: A collector for electric machines, including a rotationally symmetrical sintered ceramic body and a plurality of radially disposed metallic segments which are separated from each other by one interspace each and which are bonded to the ceramic body via a eutectic intermediate layer. The segments are bonded to the ceramic body in accordance with the eutectic method by being surface-oxidized on their inside narrow side and radially pressed against the ceramic body with the totality being brought to the melting temperature corresponding to the metal/metal-oxide eutectic and subsequently being cooled down again. A preferred embodiment includes: copper segments on an Al.sub.2 O.sub.3 ceramic body.

    摘要: A gate-turn-off power semiconductor device of the GTO or FCTh type, having a control zone of alternately arranged finely subdivided cathode fingers and gate trenches, wherein the gate trenches are constructed as narrow deep slots, preferably by a crystal-direction-selective wet chemical etching process, while the original substrate surface is retained in the remaining area of the semiconductor substrate. Compared with the conventional "recessed-gate" construction, this quasi-planar construction offers a number of advantages in the electrical behavior, in the integration of auxiliary functions and in the production.

    摘要: A process for manufacturing a power semiconductor component having a component of this type is presented which has at least three consecutive layers and possessing a high current capacity and small power losses. For contacting the first two layers, the component has first second metallized contact planes, which impress a step-like structure onto a first surface of the component. The steps have a height of between 10 and 20 .mu.m and a width of between 20 and 300 .mu.m. The ratio between the surface area of the first contact plane and the surface area of the second contact plane is between 1 and 4. The first layer is heavily doped and has a maximum thickness of 8 .mu.m, and the second layer is lightly doped and has a maximum thickness of 40 .mu.m. According to the process for manufacturing the component, the surface structure according to the invention is produced essentially by a reactive ion-etching process with a single aluminum mask.

    摘要: A ceramic/metal element, in which a metal layer (1) is firmly bonded to a ceramic substrate (2) after cooling and consequent solidification of a previously liquid eutectic interlayer (3), wherein the metal layer (1) has at least approximately the same or a greater thickness (D) than the ceramic substrate (2) and is composed in the manner of a mosaic from individual, predominantly loosely adjoining metal elements (1). By using the composite structure of the present ceramic/metal element, fracture of the ceramic substrate and curvature of the composite ceramic/metal element is avoided.
