Chemical Shrink

Chemical shrink is a post-resist-patterning process. Combining effects of physical and chemical interactions with photoresists sidewalls, a layer with reduced water solubility is formed. Post simple water rinse to remove excessive materials, the trench or hole pattern is shrunk to a smaller dimension. The volume of shrinkage is process controlled during standard bake temperatures.
