发明名称 Method for manufacturing a capacitor electrode structure
摘要 A method for manufacturing a capacitor electrode structure, according to which the following steps are executed: A substrate is provided, which comprises contact pads arranged in lines and rows on a surface of the substrate. The lines are non-parallel to the rows. A first mold is applied on the substrate. At least one first trench is formed into the first mold above the contact pads. The first trench spans over at least two contact pads arranged in one row. A first dielectric layer is applied on side walls of the at least one first trench for forming first supporting walls. A second mold is applied on the substrate. At least one second trench is formed into the second mold above the contact pads. The second trench spans over at least two contact pads arranged in one line. A second dielectric layer is applied on side walls of the at least one second trench for forming second supporting walls. And a conductive layer is applied on the first and second supporting walls for forming a first electrode of the capacitor structure.
