The invention concerns a method for the determination of layer thickness ranges of layers of a specimen, in which the reflection spectrum of the specimen is measured in a specified wavelength range and then smoothed, the number of extremes in the smoothed reflection spectrum is determined, and the determination of the layer thickness ranges is accomplished by comparison with the number of extremes in the modeled reflection spectra, such that for each layer the thickness in that layer is varied in steps having a predetermined increment, and a reflection spectrum is modeled. In a method of this kind, the wavelength range and the increments are specified in self-consistent fashion using a sensitivity criterion.

The present invention concerns a double confocal scanning microscope having an illuminating beam path (1) of a light source (2) and a detection beam path (3) of a detector (4), and in order to eliminate at their cause the problems of reconstruction methods. To do so, at least one optical component (24, 25) acting on the illuminating and/or detection beam path (1, 3) is provided, and is configured in such a way that it influences the amplitude and/or phase and/or polarization of the light; and the characteristics of the double confocal illumination and/or detection are thereby modifiable.

The invention relates to signal transmission. The use of the invention for transmitting and receiving quadrature amplitude modulation signals on unlicensed frequency bands makes it possible to lower a demodulation threshold owing to a low synchronization threshold. The inventive method consists in extending a burst of M m-level quadrature amplitude modulation signals with the aid of two pseudo-random sequences, one of which is periodically inverted in some bursts, thereby making it possible to extract, on a receiving side, the quadrature amplitude modulation signal components corresponding to a meander signal of the pseudo-random sequence inversion (the frequency of which is known). The inventive method is carried out by means of a corresponding system in a hardware and software mode. Moreover, said method can be used for synchronizing the reception of quadrature amplitude modulation signals.

The inventive method and device for vacuum-compression micro plasma oxidation relate to electrochemical processing of metal, in particular to micro plasma treatment in electrolyte solutions. The aim of said invention is to develop a method for obtaining qualitatively homogeneous coatings by micro-plasma oxidation on large-sized parts, including irregular shaped parts, or simultaneously on a great number of small parts. The second aim of the invention is to design a device for processing parts, having an extended surface area, by using low-power supplies. The inventive method for vacuum-compression micro-plasma oxidation of parts consists in dipping a processable part into an electrolyte solution pre-filled in a sealed container, in generating micro-plasma discharges on the surface of said part and, subsequently, in forming a coating, wherein the micro-plasma discharges are formed in low-pressure conditions above the electrolyte solution. The device for carrying out said method comprises means for forming vacuum in the electrolyte-containing container and additional means for pumping air.

A new pixel in semiconductor technology comprises a photo-sensitive detection region (1) for converting an electromagnetic wave field into an electric signal of flowing charges, a separated demodulation region (2) with at least two output nodes (D10, D20) and means (IG10, DG10, IG20, DG20) for sampling the charge-current signal at least two different time intervals within a modulation period. A contact node (K2) links the detection region (1) to the demodulation region (2). A drift field accomplishes the transfer of the electric signal of flowing charges from the detection region to the contact node. The electric signal of flowing charges is then transferred from the contact node (K2) during each of the two time intervals to the two output nodes allocated to the respective time interval. The separation of the demodulation and the detection regions provides a pixel capable of demodulating electromagnetic wave field at high speed and with high sensitivity.

The invention relates to a flip-chip module with a semiconductor chip with contact posts, wherein the contact posts are connected electrically and mechanically to a substrate. Provided between the substrate and the semiconductor chip is a spacer, which is coupled mechanically to the substrate and/or the semiconductor chip. By this means, thermal stresses in the flip-chip module are absorbed by the spacer and kept away from the semiconductor chip.The invention also relates to a method for the production of a flip-chip module, in which firstly a spacer is located between the semiconductor chip and the substrate, after which the contact posts are soldered to the contact points of the substrate. Through the provision of the spacer the distance between the semiconductor chip and the substrate is set precisely, thereby improving the quality of the soldering points.
