Abstract
A method for forming a semiconductor substrate arrangement includes: forming a mask on a semiconductor substrate, the semiconductor substrate including and a metallization layer arranged on an insulation layer, the metallization layer arranged between the mask and insulation layer; forming a layer of electrically conductive coating on the metallization layer, the electrically conductive coating formed in at least one opening of the mask on regions of the metallization layer that are not covered by the mask; and after forming the electrically conductive coating, removing the mask. Forming the mask includes either applying an even layer of material on the metallization layer, or applying the material of the mask on the metallization layer such that the thickness of the mask in a region adjacent to edges of the mask is greater than the thickness of the regions of the mask further away from the edges.
