Abstract
A method for manufacturing a capacitive device comprising the following steps: i) provide a substrate comprising: a first area made of a first material and/or having a first texture, a second area made of a second material and/or having a second texture, a third area made of a third material and/or having a third texture, ii) make nanopillars grow over the substrate with which a nanopillar layer is obtained locally having different densities, the density of the first area being lower than the density of the third area, iii) deposit an insulating layer, iv) deposit a conductive layer, with which a capacitive stack is formed at the first area, the capacitive stack comprising the insulating layer and the conductive layer.
