    摘要: A photomask for use in photolithography has substrate, a main pattern at one side of the substrate, and a transparency-adjusting layer at the other side of the substrate. The transparency-adjusting layer has a characteristic that allows it to change the intensity of the illumination incident on the main pattern during the exposure process accordingly. In manufacturing the photomask, a first exposure process is carried out on a wafer using just the substrate and main pattern. The critical dimensions of elements of the pattern formed on the wafer as a result of the first exposure process are measured. Differences between these critical dimensions and a reference critical dimension are then used in designing a layout of the transparency-adjusting layer in which the characteristic of the layer is varied to compensate for such differences.

    摘要: Disclosed is a method of forming a pattern. A first organic polymer layer is formed on a substrate on which an underlying layer, and then a second organic polymer layer, which has an opening partially exposing the first organic polymer layer, is formed on the first organic polymer layer. Next, a silicon-containing polymer layer is formed on the second organic polymer layer to cover the opening. The silicon-containing polymer layer is oxidized and simultaneously the second organic polymer layer and the first organic polymer layer are ashed by oxygen plasma to form a pattern having an anisotropy-shape. The underlying layer is etched using the silicon-containing polymer layer and the first organic polymer layer as an etching mask to form a pattern.

The buffer layer may be anisotropically etched using the second etch mask pattern as an etch mask, forming a buffer layer pattern. The second hard mask layer may be anisotropically etched using the first etch mask pattern and/or the buffer layer pattern as etch masks, forming a second hard mask pattern.

    摘要: Multilayer alignment keys in an integrated structure and a method of aligning using the keys are provided. Alignment keys are formed on a semiconductor substrate in a multilayer structure. The length of the alignment key in one layer can be different from that of the alignment key in underlying and/or overlying layer. Alternatively, the number of alignment keys can be different in each layer. Thus alignment weight can be imposed differently on each layer, thereby increasing alignment accuracy.
