从 High NA EUV 到 MEMS 微镜：把图形成形与光学验证分开说明From High NA EUV to MEMS mirrors: distinguish patterning results from optical validation
今天关注两条近期官方消息。下方工艺观察与项目准备为微纳Hub 编辑解读，不代表来源机构的实验结论。Two recent official updates are in focus. The process and preparation notes below are MN Fab Hub editorial interpretation, not experimental conclusions from the source institutions.
光刻：22 nm 是节距，检测阶段也要写清。Lithography: 22 nm is pitch; specify the inspection stage.
imec 9 月 8 日报告，化学放大胶（CAR）结合单次 High NA EUV 曝光，可实现低至 22 nm 节距的线/空图形，并展示 28 nm 中心距通孔。来源图像区分显影后检测（ADI）和刻蚀后检测（AEI）；这些研究结果不等于整套节点已量产。On September 8, imec reported CAR-based single-exposure High NA EUV patterning down to 22 nm line/space pitch and vias at 28 nm center-to-center spacing. Its images distinguish after-development inspection (ADI) from after-etch inspection (AEI). These results do not establish production readiness for an entire node.
微镜：用评估套件验证应用条件。Micromirrors: validate application conditions with evaluation kits.
Fraunhofer IPMS 9 月 8 日介绍基于 MEMS 的空间光调制器。其衍射 MEMS 套件采用 256 × 256 个可独立驱动的倾斜微镜，单元边长 16 μm，并提供驱动电子学与软件。套件可用于应用评估；像素数和单元尺寸本身不能代表系统光学分辨率。Fraunhofer IPMS described MEMS spatial light modulators on September 8. Its diffractive MEMS kit uses 256 × 256 individually addressable tilting mirrors with a 16 μm edge length, alongside drive electronics and software. The kit supports application evaluation; pixel count and mirror dimensions alone do not define system optical resolution.
一个工艺观察Process Note
把结构指标和功能指标分别验收。Validate structure and function separately.
我们的工艺观察：光刻项目需分别记录胶上图形与刻蚀转移后的尺寸；微光学项目则应把微镜几何参数与实际光路测试分开。对比不同结果前，先统一检测阶段、波长和测试对象，避免把不同口径的数字直接排名。Our process note: record resist-pattern dimensions separately from dimensions after etch transfer. For micro-optics, distinguish mirror geometry from optical-system tests. Align inspection stage, wavelength and measurement object before comparing results.
项目准备提醒Project Prep
交接时附上两张验收清单。Prepare separate structural and functional checklists.
结构清单写明材料、膜层、线宽与节距、检测阶段和测量位置；功能清单写明工作波长、入射条件、驱动接口与目标测试。已有样品请附带版图版本和测量记录。微纳Hub 可协助梳理工艺路线与资源匹配。For structure, list materials, layers, linewidth and pitch, inspection stage and measurement locations. For function, specify wavelength, illumination conditions, drive interfaces and target tests. Include layout versions and measurement records for existing samples. MN Fab Hub can help organize process routing and resource matching.
