Abstract: A via hole defining process performed in one chamber is described. A substrate with a dielectric layer thereon is provided. A patterned mask layer having an opening therein is formed on the dielectric layer. An anisotropic etching process is conducted to form a via hole in the dielectric layer within an etching chamber by using the patterned mask layer as a mask. A portion of the patterned mask layer around the via hole is then removed by an oxygen (O2) treatment in the same etching chamber, while the profile of the via hole is retained. Another anisotropic etching process is conducted in the same etching chamber to remove a portion of the dielectric layer to broaden the upper portion of the via hole. Because the via hole defining process is performed within one single chamber, the whole process time can be decreased.

Abstract: A method for in-line monitoring of via/contact etching process based on a test structure is described. The test structure is comprised of via/contact holes of different sizes and densities in a layout such that, for a certain process, the microloading or RIE lag induced non-uniform etch rate produce under-etch in some regions and over-etch in others. A scanning electron microscope is used to distinguish these etching differences in voltage contrast images. Image processing and simple calibration convert these voltage contrast images into a “fingerprint” image characterizing the etching process in terms of thickness over-etched or under-etched. Tolerance of shifting or deformation of this image can be set for validating the process uniformity. This image can also be used as a measure to monitor long-term process parameter shifting, as well as wafer-to-wafer or lot-to-lot variations.
