摘要： A method is provided for forming an error diffusion-derived sub-resolutional grayscale reticle. The method forms at least one partial-light transmissive layer overlying a transparent substrate. At least one unit cell in formed in the transmissive layer. The unit cell is formed by selecting the number of reduced-transmission pixels in the unit cell, and forming a sub-pattern of reduced-transmission pixels in the unit cell. The unit cell is sub-resolutional at a first wavelength.

摘要： A sub-resolutional grayscale reticle and associated fabrication method have been presented. The method provides a transparent substrate, and forms a plurality of coincident partial-light transmissive layers overlying the transparent substrate. A pattern is formed, sub-resolutional at a first wavelength, in at least one of the transmissive layers. If there are n transmissive layers, the reticle transmits at least (n+1) intensities of light. In one aspect, each of the plurality of transmissive layers has the same extinction coefficient and the same thickness. In other aspects, the transmissive layers may have different thickness. Then, even if the extinction coefficients are the same, the attenuation of light through each layer is different. The transmission characteristics of the reticle can be further varied if the transmissive layers have different extinction coefficients. Likewise, the transmission characteristics through the sub-resolutional patterns can be varied.
摘要翻译：已经提出了一种亚分辨灰度标线和相关的制造方法。该方法提供透明基板，并且形成覆盖透明基板的多个重合部分透光层。在至少一个透射层中形成在第一波长处副溶液的图案。如果存在n个透射层，则光罩传播至少（n + 1）个光强。在一个方面，多个透射层中的每一个具有相同的消光系数和相同的厚度。在其它方面，透射层可以具有不同的厚度。那么即使消光系数相同，每层的光的衰减也是不同的。如果透射层具有不同的消光系数，则可以进一步改变掩模版的透射特性。同样，可以改变通过子解决图案的传输特性。
