Abstract:
1. A method for directly depositing razor structures on a substrate surface comprising the steps of: a. depositing a first photo-resist layer on said substrate surface; b. exposing and developing said first photo-resist layer to form a first photo-resist region generally perpendicular to said substrate surface; c. providing a mask disposed on the first photo-resist region; d. positioning said mask such that said mask is generally parallel to and spaced from said first photo-resist region wherein said mask forms an overhang over said first photo-resist region; e. depositing a razor material directly onto the substrate surface at an angle to said substrate surface, said angle being such that said overhang provides blocking for said razor material from an upper portion of said first photo-resist region, whereby said razor material is deposited against said first photo-resist region and disposed directly on the substrate surface; and f. removing said mask and said first photo-resist region, thereby leaving said razor material that was deposited against said first photo-resist region in step e, disposed directly on the substrate surface.
