Shrinkage of critical dimensions in a semiconductor device by selective growth of a mask material

摘要

In sophisticated semiconductor devices, manufacturing techniques and etch masks may be formed on the basis of a mask layer stack which comprises an additional mask layer, which may receive an opening on the basis of lithography techniques. Thereafter, the width of the mask opening may be reduced by applying a selective deposition or growth process, which thus results in a highly uniform and well-controllable adjustment of the target width of the etch mask prior to performing the actual patterning process, for instance for forming sophisticated contact openings, via openings and the like.
