Abstract: A device includes a joining partner, which protrudes at a submersion depth into a recess filled at least partially with a fixing element in a substrate surface of a substrate. A compensating element is situated between the joining partner and the fixing element. The compensating element is situated at least partially in the fixing element within the submersion depth of the joining partner. Accordingly, the compensating element is in contact with the joining partner and with the fixing element. In this way, an expansion change or a movement of the fixing element, of the substrate or of the joining partner may be compensated for by a compression or elongation of the compensating element. A crack formation may be avoided or its effect may be minimized by the sealing function.
