    Abstract: A structure applied to a photolithographic process is provided. The structure comprises at least a film layer, an optical isolation layer, an anti-reflection coating and a photoresist layer sequentially formed over a substrate. In the photolithographic process, the optical isolation layer stops light from penetrating down to the film layer. Since the optical isolation layer is set up underneath the photoresist layer, light emitted from a light source during photo-exposure is prevented from reflecting from the substrate surface after passing through the film layer. Thus, the critical dimensions of the photolithographic process are unaffected by any change in the thickness of the film layer.

    Abstract: A template padding method for padding edges of at least one hole on a semiconductor mask. The exposure and padding process is modulized. A padding database is developed based on the feature size and the pattern to be exposed. In the method of the present invention, the environment to be exposed is found firstly, and specific exposure module is then searched out. The padding result of the module is pre-found and stored in a database by diffraction operation, such as OPC method. Padding of a hole on a mask about a cell of a wafer can be performed directly by using a value stored. The complicated calculation can be greatly reduced. The method is adjustable according to the feature size of the product and the exposing pattern. The method can be used to random-distribution of holes on a mask surface, so as to determine a padding area effectively.

    Abstract: The invention provides a method for reducing roughness of the photoresist through cross-linking reaction of deposit and the photoresist. The method comprises at least performing an exposure process to a substrate having a photoresist pattern and performing a post-exposure bake process for activating the surface of photoresist pattern. A material layer is formed to cover the surface of the photoresist pattern. The material layer cross-links with the hydrogen ions on the surface of the photoresist pattern, so that a filling layer is formed to fills asperity or the rough regions of the photoresist pattern.
