    摘要: A non-ESL semiconductor interconnection structure and a method of forming the same are provided. The non-ESL semiconductor interconnection structure includes a first low-k dielectric layer comprising a first region and a second region overlying the substrate, a plurality of conductive features in the first low-k dielectric layer, a cap layer on at least a portion of the conductive features, and a dielectric capping layer overlying the first low-k dielectric layer in the second region but not in the first region. The conductive features in the second region have a substantially greater spacing than the conductive features in the first region. The dielectric capping layer preferably has an inherent compressive stress.

    摘要: A method and apparatus for dispensing a liquid etchant onto a wafer dispenses the liquid etchant onto a wafer using a scanning dispensing nozzle while controlling the dispensing temperature of the etchant in real time as a function of the radial position of the dispensing nozzle over the wafer. The dispensing temperature of the etchant is controlled to enhance the effectiveness of the etchant and thus compensate for the lower etching rate zones in the wafer.
