Claim 16:
17. The method according to claim 16, wherein the forming the first and second spacer elements comprises:
fixing a spacing wafer to a transport wafer, the spacing wafer having a first surface and a second surface, and the transport wafer having a first surface and a second surface, the first surface of the spacing wafer and the first surface of the transport wafer facing one another;
forming in the spacing wafer a duct cavity, which extends from a second surface of the spacing wafer to the first surface of the spacing wafer, the duct cavity separating the first spacer element and the second spacer element from one another;
fixing the first semiconductor body to the spacing wafer, the first surface of the first semiconductor body facing the second surface of the spacing wafer;
uncoupling the spacing wafer and the transport wafer from one another; and
fixing the second semiconductor body to the spacing wafer, the first surface of the second semiconductor body facing the first surface of the spacing wafer.
