    摘要: A method for providing an oxide layer on a semiconductor substrate is disclosed. In one aspect, the method includes obtaining a semiconductor substrate. The substrate may have a three-dimensional structure, which may comprise at least one hole. The method may also include forming an oxide layer on the substrate, for example, on the three-dimensional structure, by anodizing the substrate in an acidic electrolyte solution.

    摘要: Ultra-low capacitance interconnect structures, preferably Through Silicon Via (TSV) interconnects and methods for fabricating said interconnects are disclosed. The fabrication method comprises the steps of providing a substrate having a first main surface, producing at least one hollow trench-like structure therein from the first main surface, said trench-like structure surrounding an inner pillar structure of substrate material, depositing a dielectric liner which pinches off said hollow trench-like structure at the first main surface such that an airgap is created in the center of hollow trench-like structure and further creating a TSV hole and filling it at least partly with conductive material.
