Patent ID: 8501395

Claim:
A method of patterning a structure comprising: above a layer on a substrate; exposing the photoresist layer with a pattern of polarized light; performing a post-exposure bake on the exposed photoresist layer; developing the photoresist layer to form a pattern photoresist layer; applying a shrink coating over the patterned photoresist; baking the shrink coating to form a reduced spacing patterned photoresist layer; rinsing the shrink coating from the reduced spacing patterned photoresist layer; after rinsing said shrink coating from the reduced spacing patterned photoresist layer, measuring a critical dimension (CD) of the reduced spacing patterned photoresist layer, and if no further reduction in spacing is to be performed, performing a post develop bake of the reduced spacing patterned photoresist layer; and after preforming said post develop bake etching said layer in alignment with said reduced spacing patterned photoresist layer.
