A method for manufacturing electrically non-active structures for an electronic circuit integrated on a semiconductor substrate is provided, with the electronic circuit including first and second electrically active structures. The method includes inserting the electrically non-active structures in the electronic circuit to make uniform a surface above the semiconductor substrate. The inserting includes identifying, among the electrically non-active structures, a first group of electrically non-active structures to be adjacent the first and second electrically active structures, and identifying, among the electrically non-active structures, a second group of electrically non-active structures not adjacent to the first and second electrically active structures. The method further includes defining, on the semiconductor substrate, the first and second groups of electrically non-active structures through different photolithographic steps.
