Abstract: A brake disk is made up essentially of a brake cup and a friction ring. The friction ring includes two friction ring halves, between which cooling channels are situated. Additional air routing elements are situated at the level between the friction ring halves. The brake disk has especially satisfactory cooling characteristics.

Abstract: A composite material, a composite component made thereof, and a method for producing a metal-ceramic composite material or a composite component are provided. The composite material or the composite component is produced by the method described in the following. In a first step, a porous ceramic preform is produced from a ceramic starting mass, and in a second step the infiltration of the porous ceramic preform with a molten metal takes place, the ceramic starting mass having a ceramic main component and a ceramic minor component that reacts with this main component, and the minor component reacts at least partially with the main component during the first and/or second step.

An alloy of copper and at least one additional metal is used as the metal melt for infiltration, the additional metal being converted by at least one reactive component of the blank in such a way that a pore space of a ceramic phase is filled essentially with pure copper.

Abstract: The novel trench capacitors have a constant or increased capacitance. Materials for a second electrode region and if appropriate a first electrode region include a metallic material, a metal nitride, or the like, and/or a dielectric region is formed with a material with an increased dielectric constant. An insulation region is formed in the upper wall region of the trench after the first electrode region or the second electrode region has been formed, by selective and local oxidation.

Abstract: The present invention provides a method for fabricating a semiconductor component having a substrate (1) and a dielectric layer (70) provided on or in the substrate (1), the dielectric layer (7) being deposited in alternating self-limiting monolayer form, in the form of at least two different precursors, by means of an ALD process.
