Latest Patents
One of his latest patents is titled "Mask using lithographic image size reduction." This patent discloses a process for reducing lithographic image size for integrated circuit manufacture. A mask of photosensitive material is formed on a substrate, with an opening of a minimum size dictated by the limits of lithography. The reduction in image size is achieved by establishing sidewalls to the interior vertical surfaces of the opening through the deposition of a conformal layer, followed by anisotropic etching. The dimension of the opening is reduced by the combined thickness of the two opposite insulator sidewalls. This innovative process allows for the creation of a photomask or stencil with a pattern of openings smaller than what is possible through traditional lithography.
