Abstract:
Methods and structures for forming a contact hole structure are disclosed. These methods first form a substantially silicon-free material layer over a substrate. A material layer is formed over the substantially silicon-free material layer. A contact hole is formed within the substantially silicon-free material layer and the material layer without substantially damaging the substrate. In addition, a conductive layer is formed in the contact hole so as to form a contact structure.
