The invention provides a generation method of generating data of a mask, comprising a calculation step of calculating an aerial image formed on an image plane of a projection optical system, an extraction step of extracting a two-dimensional image from the aerial image, a determination step of determining a main pattern of the mask based on the two-dimensional image, an extraction step of extracting, from the aerial image, a peak portion at which a light intensity takes a peak value in a region other than a region in which the main pattern is projected, a determination step of determining an assist pattern based on the light intensity of the peak portion, and a generation step of inserting the assist pattern into a portion of the mask, which corresponds to the peak portion, thereby generating, as the data of the mask, pattern data including the assist pattern and the main pattern.

Process for production of photographic masks for tonal correction by dry dot etching comprising exposing a mask film, e.g., positive film, behind a film combination of half-tone positives and negatives that contains at least one pair of a positive and a negative of the same color separation, said pair being separated from one another by a spacer film, e.g., transparent, matt film, etc. The half-tone values at the points to be corrected are in the range of 30-70%.

1,263,122. Photographic processes. W. R. GRACE & CO. Feb.3, 1969 [June 10, 1968], No.44961/71. Divided out of 1,263,121. Heading G2C. A photographic process for producing photocured images which comprises imagewise exposing a photo-curable layer on a transparent support through the support, uniformly exposing through the support to cure up to 10 mils of the layer from the support and developing to remove the uncured areas of the layer. The developed image may again be uniformly exposed to harden it. Preferred photo-curable compositions are those of Specifications 1,215,591, 1,251,232, 1,102,910 and 1,007,345. Development may be by ultrasonic cleaning as disclosed in Specification 1,263,121.

Contrast enhancing exposure apparatus and method for use in semiconductor fabrication are described. In one embodiment, a method for forming a pattern on a substrate, wherein the substrate includes a photoresist layer comprising photoacid generators (“PAGs”) and photobase generators (“PBGs”), is described. The method includes dividing the pattern into two component patterns; exposing the photoresist layer of the substrate to UV light through a first mask corresponding to a first one of the component patterns; subsequent to the exposing the photoresist layer of the substrate to UV light through the first mask, exposing the photoresist layer of the substrate to UV light through a second mask corresponding to a second one of the component patterns, wherein the PAGs and PBGs disposed in areas of the photoresist layer that have been exposed to UV light at least twice are activated and wherein the activated PAGs neutralize the activated PBGs in areas of the photoresist layer that have been exposed to UV light at least twice.

The present invention provides a new process for the production of masked subtractive positive color images by the silver dye bleach process, which comprises the steps of exposure, silver developing, dye-bleaching, silver-bleaching and fixing. The photographic material used contains, in at least two layers, one image-wise bleachable dye per layer, the absorption maximum of the dye corresponding in each case to one of the three primary colors red, green and blue and a silver halide emulsion layer sensitive in a specific spectral region being allocated to each dye, wherein this material (a) in at least one layer contains a dye, the undesired secondary color density of which is to be compensated, and a silver halide emulsion containing silver iodide is allocated to this dye, in the same layer and/or an adjacent layer, (b) in at least one further layer contains at least one further dye, the main color density of which corresponds to a secondary color density, which is to be compensated, of the first dye, and also a silver halide emulsion free from iodide ions, (c) contains a further layer which is adjacent to layer (b) and contains colloidal nuclei which are able, under reducing conditions, to deposit metallic silver from soluble silver complexes, and also contains an insensitive iodide-free silver halide emulsion which is not spectrally sensitized, and optionally a stabilizer, and (d) containing a separating layer, which does not contain any of the dyes of the layer or layers (a), between the layer or layers (a) and the layer (c). The silver developing bath with which the material is treated contains ligands which form water-soluble and diffusible silver complexes with silver.

摘要:
A full phase shifting mask (FPSM) can be advantageously used in a damascene process for hard-to-etch metal layers. Because the FPSM can be used with a positive photoresist, features on an original layout can be replaced with shifters on a FPSM layout. Adjacent shifters should be of opposite phase, e.g. 0 and 180 degrees. In one embodiment, a dark field trim mask can be used with the FPSM. The trim mask can include cuts that correspond to cuts on the FPSM. Cuts on the FPSM can be made to resolve phase conflicts between proximate shifters. In one case, exposing two proximate shifters on the FPSM and a corresponding cut on the trim mask can form a feature in the metal layer. The FPSM and/or the trim mask can include proximity corrections to further improve printing resolution.

A photoplotter supports a sheet of photosensitive material for exposure by an associated light source. A light valve device interposed between the light source and the sheet has a main face parallel to the sheet divided into a plurality of subareas or pixels the light transmissivities of which are individually controlled through an associated computer to cause the exposure to be that of a desired graphic or artwork.
