Abstract: A recordable compact disc comprises a 0.6 millimeter clear plastic or glass substrate on which is grown a thin-film image layer having several distinct recording planes. Each recording plane is separated from the next by a clear plastic layer. Each recording plane includes an organic dye layer in combination with another clear layer that has a different index of refraction. Different color dyes are used for each recording plane.A method for storing and reading data to and from a multilayer recordable compact disc with different color dye layers uses high powered color lasers to write each recording plane and low powered monochromatic reading lasers that are sensitive to the constructive and destructive light interference effects caused by micron variations in the clear plastic layers in each recording plane. The micron variations used for each recording plane are unique and chosen along with the monochromatic reading laser colors to have minimal crosstalk between recording-plane data channels.

Abstract: An optical disk records digital information in optically-reflective layers that each vary in thickness between constructive interference of a monochromatic light and destructive interference of the said monochromatic light. The difference in the intensity of a reflected light beam subjected to interferometric constructive and destructive interference is used to communicate digital data from the optically-reflective layers and a detector. The optical disk provides for multiple layers of digital information that are tuned for interferometric response at correspondingly different monochromatic wavelengths of light. Another embodiment of the present invention is a mass-production process for making such an interferometric optical disk. Another embodiment of the present invention is a variation that includes layers that are emitting or absorbing depending on dopants.

Abstract: An embodiment of the present invention is a process in which a polymer solution is spin coated onto a master data recording disk, such as glass substrate with photoresist images, before separating. After drying and forming polymer, a polymer membrane results which is a faithful reproduction of micron-sized optical recording features on the surface of the master. Such membrane is either peeled-off and mounted to a pellicle-like frame or first laminated to a stiffer, stronger substrate before peeling to support the duplicate.

Abstract: A pellicle for use on a photomask reticle in conjunction with deep ultraviolet light wavelengths. The membrane of the pellicle comprises a purified fluoropolymer that has been spin coated on a glass substrate treated with a surface modifier and then separated and mounted on an aluminum frame. The aluminum frame has vents that filter air of contaminants and which allow an equalization of air pressure on both sides of the pellicle membrane when a peel-off backliner is in place on the opposite side of the frame. A permanent bond is made between the membrane and frame and a sticky adhesive is used to keep the backliner on the frame until peel-off. The sticky adhesive is such that the backliner may be re-attached a plurality of times.

Abstract: Mid and deep ultraviolet light transmitting pellicles for protecting photomasks from particle contamination during a projection printing process. The pellicles are manufactured from polyglycidyl-methacrylate-ethacrylate copolymer, from polyvinyl butyral polymer or from nitrocellulose. The polyvinyl butyral pellicle is sandwiched between two layers of an antireflective coating of poly-1H, 1H Pentadecafluorooctyl methacrylate or poly-1H, 1H Pentadecafluorooctyl acrylate. The nitrocellulose pellicle includes two double layers of antireflective material with the first double layer positioned on one side of the nitrocellulose layer and comprising a layer of the thermoplastic phenolic resin novalac and a layer of either poly-1H, 1H Pentadecafluorooctyl methacrylate or poly-1H, 1H Pentadecafluorooctyl acrylate.
