Abstract: A method of fabricating an electrical contact through a through hole in a substrate, wherein the through hole is at least in part filled with a liquid conductive material and the solidified liquid conductive material provides an electrical contact through the through hole.

Abstract: A method for placing material onto a target board by means of a transfer board comprising a plurality of blind holes, the method comprising the steps of immersing the transfer board in a material bath, wherein a first pressure acts on the material bath and a second pressure acts in the blind holes, and wherein the first pressure and the second pressure are substantially equal; generating a pressure difference between the first pressure and the second pressure, so that the blind holes of the transfer board are filled at least partially with the liquid material; extracting the transfer board from the material bath; and positioning the transfer board opposite to the target board, the material being expelled from the blind holes, such that the material touches the target board.

Abstract: Carrier including: a substrate having a first interface with first contact holes, and a second interface, which lies opposite the first interface, with second contact holes. The substrate includes a substrate body and electrically conductive contact channels formed therein, wherein each of the contact channels electrically conductively connects a first contact hole to a second contact hole. The carrier also includes a front-side wiring layer arranged on the first interface and; has a first front-side metallization layer formed therein such that it includes a first capacitor electrode for electrically connecting microelectronic devices and/or circuits to a first pole of a signal or supply voltage.

Abstract: Method for producing a macroporous silicon substrate suitable as a carrier for microelectronic components. Blind holes are produced from a front surface of the substrate. An insulator layer is produced on the front and rear surfaces of the substrate. Selective isotropic etching is performed from the rear surface with uncovering of blind hole ends produced such that respective blind hole walls formed by the insulator layer project from the substrate on the rear surface and are defined in this region only by the insulator layer forming the respective blind hole wall. A further insulator layer is then produced on the surfaces of the substrate. A plurality of the blind holes are then filled with a metal or a metal alloy by introducing the substrate into a melt thereof under pressure in a process chamber containing the melt. The melt is then asymmetrically cooled in the blind holes from the front surface, so that the metal or the alloy contracts toward and lies on a plane with the rear surface of the substrate.
