Abstract: A flat panel field emission device includes a black matrix formed from an electrically insulative material such as praseodymium-manganese oxide. The insulative black matrix increases image contrast and reduces power consumption. For field emission devices which utilize a switched anode for selectively activating pixels, the insulative material reduces or eliminates problems associated with short circuiting of the pixels.

Abstract: A process is provided for forming spacers useful in large area displays. The process comprises steps of: forming bundles or boules comprising fiber strands which are held together with a binder; slicing the bundles or boules into slices; adhering the slices on an electrode plate of the display; and removing the binder. In the step of forming bundles or boules comprising fiber strands, the function of the binder is initially or fully performed by glass tubings surrounding the glass fibers. The clad glass of the envelopes etches more readily than the core glass.

Abstract: A method for adjusting one or more dimensions of a photomask subsequent to etching of a defective pattern in the chrome-containing layer thereof is provided. The method includes subjecting the chrome-containing layer of a photomask to a wet etch process utilizing a solution comprising deionized water and ozone. The length of exposure is directly proportional to the degree of adjustment desired. That is, if a small adjustment in one or more dimensions of a photomask is desired, the photomask may be exposed to the deionized water and ozone solution for only a few moments, whereas if a much larger adjustment is necessary, the photomask may be exposed to the solution for several hours. Accordingly, the method of the present invention provides a way in which dimensions of a photomask may be adjusted by a small amount (e.g., a few angstroms) or more severely adjusted, for example, by 20–30 nanometers or more.
Abstract translation: 提供了在其含铬层中蚀刻缺陷图案之后调整光掩模的一个或多个维度的方法。 该方法包括使用包含去离子水和臭氧的溶液对光掩模的含铬层进行湿式蚀刻工艺。 曝光长度与所需的调整程度成正比。 也就是说，如果希望在光掩模的一个或多个维度上进行小的调整，则光掩模可以仅暴露于去离子水和臭氧溶液只有几分钟，而如果需要大得多的调整，则光掩模可能被暴露 到解决几个小时。 因此，本发明的方法提供了一种方法，其中光掩模的尺寸可以被调整少量（例如几埃）或更严格地调节，例如20-30纳米或更多。
