摘要： A semiconductor pattern mask that might otherwise exhibit three-fold symmetry, which could give rise to distorted semiconductor features in the presence of three-leaf aberration in the optical system used to expose a semiconductor wafer through the mask, is altered to break up the three-fold symmetry without altering the semiconductor features that are formed. This accomplished by adding features to the mask that break up the symmetry. One way of achieving that result is to make the added features of “sub-resolution” size that do not produce features on the exposed wafer. Another way of achieving that result is to change existing features that do form structures in such a way (e.g., with optical elements) that changes the relative phase, amplitude or other characteristic of light transmitted through those features.

摘要： Reticles having reticle patterns suitable for reducing edge of array effects are provided. The reticle patterns have unresolvable patterns formed in the periphery areas of the reticle patterns. The unresolvable patterns are non-transparent with respect to patterning radiation. Systems incorporating the reticles are also provided. Additionally, methods of forming and using the reticles are provided.

摘要： Methods of reducing proximity effects in lithographic processes wherein an integrated circuitry pattern is transferred from a mask onto a semiconductor substrate are described. In one embodiment, a desired spacing is defined between a main feature which is to reside on a mask and which is to be transferred onto the substrate, and an adjacent proximity effects-correcting feature. After the spacing definition, the dimensions of the main feature are adjusted relative to the proximity effects-correcting feature to achieve a desired transferred main feature dimension. In another embodiment, a desired spacing is defined between a main feature having an edge and an adjacent sub-resolution feature. The edge of the main feature is moved relative to the sub-resolution feature to achieve a desired transferred main feature dimension.

摘要翻译：另外可能会出现三重对称性的半导体图形掩模，其可能在用于通过掩模暴露半导体晶片的光学系统中存在三叶像差的情况下引起失真的半导体特征，以分解三而不改变所形成的半导体特征。这通过在面具中添加特征来分解对称性来实现。实现该结果的一种方式是使得“分辨率”尺寸的附加特征在曝光的晶片上不产生特征。实现该结果的另一种方式是改变以这样一种方式形成结构的现有特征（例如，利用光学元件），其改变透过这些特征的光的相对相位，幅度或其它特性。
