    • A method and apparatus for making an integrated circuit takes advantage of both polarized and phase shifted light in order to achieve a fine feature. The feature on the integrated circuit is obtained by exposing a first region to light that has a first polarization state, exposing a second portion of the wafer to polarized light in the first polarization state but which is also phase shifted about 180 degrees. A region between the first and second region may be unexposed to light. The region between the first and the second region is the position of the fine feature. In areas where the first region and the second region need to be joined together but no feature is intended to be formed, there is a third region between the first and second regions which is exposed to polarized light that has a second polarization state which is orthogonal to that of the polarized light which exposes the first and second regions. The result is that the boundary between either the first or second region and the third region is fully exposed. Thus there is no artifact or extra feature formed in this boundary area between the first and second regions. Masks are made with corresponding regions to the first, second, and third regions so that the light in these polarized and phase shifted states is properly provided to the integrated circuit.
    • 用于制造集成电路的方法和装置利用偏振光和相移光的优点,以便实现精细特征。 通过将第一区域暴露于具有第一偏振态的光,将晶片的第二部分暴露于第一偏振状态的偏振光,但是也相移大约180度,可以获得集成电路上的特征。 第一和第二区域之间的区域可以是未曝光的。 第一和第二区域之间的区域是精细特征的位置。 在第一区域和第二区域需要连接在一起但没有要形成特征的区域中,在第一和第二区域之间存在第三区域,该区域暴露于具有正交的第二偏振态的偏振光 与暴露第一和第二区域的偏振光的偏振光。 结果是第一或第二区域与第三区域之间的边界完全暴露。 因此,在第一和第二区域之间的该边界区域中没有形成伪像或额外的特征。 掩模由与第一,第二和第三区域相对应的区域制成,使得这些极化和相移状态的光适当地提供给集成电路。

    • Multilayer film stacks and gray scale processing methods are employed for fabricating phase-shifting masks (PSMs) utilized in lithography. Desired optical transmission and phase-shifting functions of the mask are achieved by controlling the optical properties and thickness of constituent film layers. The mask can be tuned for optimal performance at various wavelengths to an extent beyond that obtainable using a single layer film to control both attenuation and phase shifting of incident light. The processing methods exploit multi-level electron beam or optical beam lithography techniques, and the etch selectivity afforded by selection of appropriate materials for the film stack, to obtain improved yields and reduced processing costs for fabrication of PSMs. In particular, diamond-like carbon (DLC) materials formed by ion beam deposition and having a stress of 1 GPa or less are utilized as etch stop layers (see Figure 6).
    • 多层膜堆和灰度处理方法用于制造在光刻中使用的相移掩模(PSM)。 通过控制构成膜层的光学性质和厚度来实现掩模的期望的光学传输和相移功能。 可以调整掩模以在各种波长下的最佳性能达到超过可以使用单层膜控制入射光的衰减和相移的程度。 该处理方法利用多级电子束或光束光刻技术,以及通过为膜堆叠选择合适的材料提供的蚀刻选择性,以获得改进的产量并降低制造PSM的加工成本。 特别地,通过离子束沉积形成并且具有1GPa或更小的应力的类金刚石碳(DLC)材料被用作蚀刻停止层(参见图6)。

    • A method for forming a photomask includes providing a transparent substrate and forming an opaque layer over at least a first portion of the transparent substrate. The opaque layer is patterned to define a mask pattern and expose at least a second portion of the transparent substrate. The second portion is etched to define a phase shifting region. The width of the phase shifting region defines a critical dimension. The critical dimension is measured, and the phase shifting region is etched based on the critical dimension to undercut the optically opaque layer. A photomask includes a transparent substrate and a phase shitting region defined in the transparent substrate. The phase shifting region includes sloped sidewalls having a slope of less than about 85 DEG .
