    摘要: A different method is provided for forming high aspect ratio damascene structures with an integrated approach of combining electroless plating with physical vapor deposition of copper. A dual damascene structure, having a trench opening and a via opening, is first formed over a metal line on a substrate. The inside walls of the dual structure is lined with a diffusion barrier layer. Then, nitride spacers are formed on the inside walls of both the trench opening and the via opening. The via opening is further lined with a displacement, or, seed, layer. This is followed by forming electroless copper in the via opening, and hence a copper plug. A barrier metal is now formed over both the copper plug and the inside walls of the trench opening. Copper is next deposited over the barrier metal inside the trench, and including over the copper metal plug, using physical vapor deposition (PVD). Any excess metal is subsequently removed by CMP, thus forming a copper dual damascene interconnect that is highly conformable for high aspect ratios, and also void-free and reliable.

    摘要: A method is disclosed for forming insulative inter metal dielectric (IMD) layers without the attendant problems of having voids, key-holes and air gaps. This is accomplished by reducing the aspect ratio of the gaps between metal lines through a judicious two-step dielectric filling process and through the use of two-step removal of the photoresist. That is, the gap is filled with photoresist first, and then partially removed, thereby leaving a portion in the gap to reduce the aspect ratio of the gap. When a second insulative layer is formed over the substrate, the gap between the metal lines is filled without the conventional attendant problem of forming voids or key-holes. Hence, void free IMD integration with improved IMD gap filling is achieved along with improved IMD thermal conductivity through the use of a metal liner.

    摘要: The method for forming a capacitor in the present invention includes the steps as follows. At first, a multi-layer structure is formed on a semiconductor substrate, and the multi-layer structure is provided to have etching selectivity in etching neighboring layers in the multi-layer structure. A top dielectric layer is then formed on the multi-layer structure. A first opening is defined in the top dielectric layer, and a second opening is defined in the multi-layer structure under the first opening. Next, a wet etch is performed through the second opening to form at least two lateral openings in the multi-layer structure. Following the wet etch, a first conductive layer is formed conformably on the top dielectric layer, on sidewalls of the first opening and the second opening, and filled within the at least two lateral openings. A filling layer is then formed on the substrate, and the filling layer and the first conductive layer on the top dielectric layer are removed. The remained filling layer, the top dielectric layer, and the multi-layer structure are removed to leave a first electrode on the substrate. Finally, an inter-electrode dielectric layer is formed on the first electrode and a second conductive layer is formed on the inter-electrode dielectric layer to finish the formation of a capacitor.

The wafer probe card includes a pitch shift assembly having a shift block that includes a reserve needle block and an adjacent functional needle block. Multiple probe needles are linearly adjustable on the shift block, and a selected number of the probe needles can be shifted from the reserve needle block to the functional needle block depending on the number of contact pads on the integrated circuit to be contacted by the probe needles of the wafer probe card during the testing process. A selected spacing between the probe needles, or pitch, can be achieved by locating the probe needles at the selected spacings from each other along the functional needle block.
