Patent ID: 8894871

Claim:
A lithography method using tilted evaporation, comprising: (a) applying a resist on top of a substrate; (b) patterning the resist using a lithography process thus forming a patterned resist and portions on the top of the substrate where the resist is removed; (c) tilt-evaporating a first thin film material on an upper layer of the patterned resist thus forming a modified pattern mask; (d) evaporating a second thin film material on the top of the substrate using the modified pattern mask; (e) tilt-evaporating the material of the first thin film on an upper layer of the second thin film material evaporated on the resist thus forming a re-modified pattern mask; (f) etching the second thin film material evaporated on the top of the substrate using the re-modified pattern mask; and (g) removing the resist from the top of the substrate.
