Solder compositions are described that include at least about 2% of silver, at least about 60% of bismuth, and at least one coupling element, wherein the at least one coupling element forms a complex with bismuth. Layered materials are also described that include a surface or substrate; an electrical interconnect; the solder composition described herein; and a semiconductor die or package. Methods of producing a solder composition are also described that include: a) providing at least about 2% of silver, b) providing at least about 60% of bismuth, c) providing at least one coupling element, wherein the at least one coupling element forms a complex with bismuth, and d) blending the silver, bismuth and at least one coupling element to form the solder composition.

A method of manufacturing an optical element having an optical surface extending close to a periphery of a substrate comprises: providing a substrate having a main surface extending beyond a periphery of the optical surface and also performing a polishing of the optical surface in regions of the main surface extending beyond the optical surface. Thereafter, material of the substrate carrying a portion of the surface extending beyond the optical surface is removed.
摘要:
By using a packer which is pushed as far over an anchor as the intended length of the moulding, the cavity in a borehole in the region of the bond can be completely filled with a reactive resin. Overhead work is possible even with slowly reacting resins. By using a catalyst on the packer, the reactive resin injected into the borehole behind the packer can be made to harden very rapidly.

摘要:
A method for operating a data receiver for audio and/or video data, wherein a planned and variable program title sequence having program titles is recorded, audio and/or video data relating to at least one program title are received via a data link and are buffered, and audio and/or video data of at least one program title are reproduced. The transmission resources of the data link for audio and/or video data to be transmitted and to be buffered are distributed over at least two program titles that have not yet been reproduced by the data receiver. Also disclosed are a data receiver associated with the method and a media reproduction system connected thereto, in particular in a vehicle.
摘要:
A method for removing at least one reflective layer (4a, 4b) from an optical element (1) for EUV lithography, wherein the optical element (1) has a substrate (2) and an interlayer (6) between the substrate (2) and the at least one reflective layer (4a, 4b). The method includes etching away the at least one reflective layer (4a, 4b) as far as the interlayer (6) with an etching gas (7), wherein the material of the interlayer (6) does not react with the etching gas (7), and wherein, after the etching away, the interlayer (6) has a surface roughness of less than 0.5 nm rms, preferably of less than 0.2 nm rms, and more preferably of less than 0.1 nm rms. Also, an optical element (1) for reflecting radiation in the EUV wavelength range includes a substrate (2), at least one reflective layer (4a, 4b), and an interlayer (6) arranged between the substrate (2) and the at least one reflective layer (4a, 4b). The interlayer (6) is composed at least partly of a material which does not react with a halogen or a halogen compound as etching gas (7) and which is selected, in particular, from one or more of the following: alkali metal halides, alkaline earth metal halides and aluminum oxide (Al2O3). The interlayer (6) has a surface roughness of less than 0.5 nm rms, preferably of less than 0.2 nm rms, and more preferably of less than 0.1 nm rms.
