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.

摘要: In directly bonding a metal to ceramics, in accordance with the invention, that surface of a metal component which is to be bonded by heating to a ceramic substrate is provided with parallel-running grooves before the preoxidation. The grooves make it possible to optimize the quantity of oxygen available at the bonding location and provide good flow behavior of the melt. As a result, a bond with good adhesion is obtained. Moreover, there is no formation of a thicker oxide layer on the free smooth surface of the metal component.
