Zusammenfassung:	A method includes forming a plurality of openings extending through a semiconductor layer, through a buried insulating layer, and into a substrate material in a second device region of a semiconductor device while covering a first device region of the semiconductor device. An insulating material is formed on sidewalls and on a bottom face of each of the plurality of openings, and a first capacitor electrode is formed in each of the plurality of openings in the presence of the insulating material, wherein each of the first capacitor electrodes includes a conductive material and partially fills a respective one of the plurality of openings.
