In a method for manufacturing a contact electrically contacting an
electrically conductive silicon structure, a substrate with a surface is
provided, the substrate having the silicon structure at the surface.
Silicon oxide is grown selectively on at least part of the silicon
structure. A layer is produced over the surface and the silicon oxide and
an opening is produced in the layer, the opening abutting on the silicon
oxide. The selectively grown silicon oxide is removed and the opening is
filled with electrically conductive material, whereby the electrically
conductive material forms the contact.
