Patent ID: 8343779

Claim:
A method for forming a pattern on a substrate (S) with an upper surface and a lower surface comprising the following steps: depositing a first layer (E 1 ) on one or more parts of the upper surface of the substrate (S), the material of the first layer (E 1 ) being opaque, depositing a photosensitive layer (R) directly on the at least one part of the first layer such that part of the photosensitive layer (R) covers at least part of the first layer (E 1 ), exposing the photosensitive layer (R) to a light beam (L), the light beam (L) impinging on the lower surface of the substrate (S) under an oblique angle (φ) of incidence, removing the exposed region of the photosensitive layer (R), depositing a second layer (E 2 ) such that part of the second layer (E 2 ) covers a remaining region of the photosensitive layer (R), wherein the second layer (E 2 ) has a thickness that allows its lifting off when removing at least a part of the remaining region of the photosensitive layer (R), and removing at least a part of the remaining region of the photosensitive layer (R.
