    摘要: A method for processing a semiconductor structure includes the steps of capping a top surface of the semiconductor structure that defines the metallization layer with a thin stop layer, forming a dielectric layer over the thin stop layer, wherein the dielectric layer defines at least one area where the thin stop layer is exposed, and removing the exposed thin stop layer to expose a top surface of the metallization layer using etchant gases substantially free from oxygen, so that the metallization layer is substantially free of damage.

    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.
