In a method for producing ferroelectric strontium bismuth tantalate having the composition SrxBiyTa2O9 (SBT) or SrxBiy(Ta, Nb)2O9 (SBTN), the element strontium, which is normally present in an amount y=2, is provided in excess in a range from 2.1≦y≦3.0. This makes it possible to carry out the heat treatment step for converting the deposited material into the ferroelectric phase at a temperature T1, which is lower than 700° C. In addition, the strontium content x can be reduced from a nominal value of 1 to 0.7.

摘要:
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. Any of the remaining unfilled blind hole ends that project from the substrate are removed.
