    Abstract: A method for producing an electrical feedthrough in a substrate having an electrical feedthrough, including: forming an etch stop layer on the front side of the substrate; forming a mask on the back side of the substrate; forming an annular trench in the substrate, which trench extends from the back to the front side, by an etching process that stops at the etch stop layer, using the mask, the trench surrounding a substrate punch; depositing a metal layer over the back side of the substrate using the mask, the metal layer penetrating into the annular trench and being deposited on the substrate punch; forming a metal silicide layer on the substrate punch by at least partially converting the metal layer into the metal silicide layer on the substrate punch; selectively removing a remainder of the metal layer; and closing off the annular trench at the back side of the substrate.
