Abstract: It has been found that for a SCALPEL lithographic system thermal effects dictate that the acceleration voltage for the exposing electrons be maintained within a specific range. This range depends on a variety of factors but is generally in the 50 to 150 KeV region. Additionally, thermal considerations also dictate the method of scanning the mask to print an entire wafer.

Abstract: A ternary surfactant system useful in reducing the propensity of silver halide elements to generate unwanted static is described. This ternary system comprises a mixture of a specific anionic and two specific nonionic surfactants and produces a surprising synergistic result. A solution of this ternary system is also useful in reducing static produced on the surface of an X-ray intensifying screen.

Abstract: Photographic glass plates are advantageously prepared by a process in which the functional layers are applied to the glass plate support by lamination. In a first form of this process, a multilayer-composite comprising antihalation, silver halide emulsion and protective overcoat layers is transferred from a flexible polymeric film support to the glass support. In carrying out this first form of the process, a release layer, protective overcoat layer, silver halide emulsion layer and antihalation layer are coated, in order, on a flexible polymeric film and laminated via an adhesive layer to a glass plate having suitable thickness and flatness for use as a photographic support. The release layer is designed to have greater adhesion to the flexible polymeric film than to the protective overcoat layer, whereby the film and release layer can be stripped off prior to the plate being put into use.
