ABSTRACT:
A method for structuring a laterally extending first layer in a semiconductor device with the aid of a reactive second layer, which together with the first layer to be structured forms first reaction products, which products are removed by material removal that acts selectively on the first reaction products, whereby the structuring takes place in a vertical direction.
