Latest Patents

Steffen Diez holds a patent for a "Method and apparatus for reproducing a programmable mask on a substrate." This invention involves imaging a pattern using a programmable mask on a substrate with a photosensitive layer. The process includes producing illumination spots on the mask through an illumination unit, which creates individual pixels via an optical unit. This forms a grid of pixels on the substrate that corresponds to the desired pattern. The invention optimally positions structure edges to be reproduced on the substrate by performing at least two exposure processes for the photosensitive layer, with the illumination spots offset from one another. This technique allows for filling spaces in the grid of pixels from the first exposure process with additional pixels from subsequent processes.
