Image reversal with ahm gap fill for multiple patterning |
abstract |
A method and apparatus for multiple patterning using image conversion are provided. The method may include depositing a gap-fill etchable hard mask using a deposition-etch-ash method to fill a gap in a pattern of a semiconductor substrate and removing the spacer etch step using a single-etch planarization method. can This method can be performed for double patterning, multiple patterning and two-dimensional patterning techniques in semiconductor manufacturing. |
