50 nm X射线光刻掩模制备关键技术
Key technology of mask making for 50 nm X-ray lithography
【摘要】 X 射线光刻(XRL)采用约 1nm 波长的 X 射线,是一种接近式光刻。就光刻工艺性能而言,XRL 能同时实现高分辨率、大焦深、大像场等,是其他光刻手段难以比拟的。由于不需要辅助工艺,因而工艺成本很低。掩模制造技术是 XRL 开发中最为困难的部分。本文介绍了适用于 50 nm XRL 的掩模制备的关键技术。
【Abstract】 The X-ray lithography of 1 nm wavelength is a step lithography. Compared to other next-generation lithography alternatives, the X-ray lithography can improve resolution, depth of focus, and exposure field sizes simultaneously. Another key advantage is the low cost. As the most difficult part of the X-ray lithography, the mask making technology for 50 nm X-ray lithography was discussed in this paper.
