Patent ID: 7709187

Claim:
A method of forming a patterned material layer on a substrate, the method comprising: a. providing a substrate having a material layer on a surface thereof; b. applying a photoresist composition on the material layer to form a photoresist layer on the material layer; c. applying a material composition on the photoresist layer to form an image modifying material layer on the photoresist layer; d. patterning the image modifying material layer to form an image modifying pattern on the photoresist layer; e. exposing the image modifying pattern and photoresist layer using imaging radiation of wavelength λ 1 such that the image modifying pattern causes an intensification of the image intensity within the photoresist layer directly beneath the image modifying pattern, wherein the image modifying pattern is not optically opaque at the imaging radiation wavelength λ 1 f. removing the image modifying pattern; g. developing portions of the photoresist layer to thereby form a patterned photoresist layer on the substrate; and h. transferring the patterned photoresist layer to the material layer.
