    摘要: A method for manufacturing an electronic component on a semiconductor substrate, including forming at least one opening in the substrate; forming in the bottom and on the walls of the opening and on the substrate an alternated succession of layers of a first material and of a second material, the second material being selectively etchable with respect to the first material and the substrate; trimming the layer portions of the first material and of the second material which are not located in the opening; selectively etching a portion of the first material to obtain trenches; and filling the trenches with at least one third material.
