电子束曝光写场拼接误差EBL field stitching errors

把连续图形、写场边界和验收位置一起交接。Connect continuous patterns, field boundaries and inspection locations.

适合什么需求Suitable projects

面向跨写场波导、光栅、大面积周期结构和长互连的 EBL 加工咨询。微纳Hub建议在询价时同时提交连续图形范围与允许的接缝偏差，并确定显影后还是转移后验收。For EBL projects with waveguides, gratings, periodic structures or long interconnects spanning write fields. MN Fab Hub recommends submitting the continuous-pattern extent and permitted seam deviation, and agreeing whether acceptance follows development or pattern transfer.

写场拼接与套刻分别是什么Stitching and overlay

JEOL 将写场解释为载台静止时由束流偏转完成的曝光区域；步进重复曝光通过写场内扫描与载台移动覆盖更大区域。相邻写场的衔接属于拼接，而与已有基底图形的位置对准属于套刻。[1] 本页关注场边界连续性，套刻标记另见相关专题。JEOL describes a write field as the region addressed by beam deflection while the stage is stationary. Step-and-repeat writing combines field exposure with stage motion. Stitching joins adjacent fields; overlay aligns a new pattern with existing substrate features. [1] This guide addresses boundary continuity; see the separate alignment-mark guide for overlay.

先确认设备与实际写场方案Confirm the tool and field plan

NIST 的 EBPG 5200+ 平台说明将高精度载台与跨写场拼接能力关联。[2] 这些资料用于理解评估项目，不代表微纳Hub或任一合作平台的交付指标。微纳Hub建议接收平台确认设备、写场尺寸、分场方式及对应条件下的近期测试结果。NIST links the high-precision stage of its EBPG 5200+ facility to pattern stitching across write fields. [2] These references inform evaluation, not delivery specifications for MN Fab Hub or partner facilities. Ask the receiving facility to confirm the tool, field size, partition plan and recent results under relevant conditions.

询价与版图交接资料Quotation and layout handoff

请提供 GDS 及单位、层号、基底和膜层、胶种胶厚、样品数量、完整曝光范围、关键线宽/间隙，以及必须连续的图形坐标。另列可调整的版图区域、预计后续刻蚀或剥离步骤、允许偏差和检测方式。已有缺陷请附带场边界位置与带标尺图像；未知项标为待确认。Provide GDS data and units, layer IDs, substrate and films, resist and thickness, sample quantity, total write area, critical widths and gaps, and coordinates of features requiring continuity. List editable regions, downstream etch or lift-off, tolerances and inspection methods. For existing defects, include field-boundary locations and calibrated images; flag unknowns.

试片与常见风险Pilot checks and common risks

微纳Hub建议平台审核关键图形能否避开场边界；必须跨场时，安排代表器件及边界测试图形，记录分场坐标与曝光条件。抽检边界处错位、断口、重叠和尺寸变化，也检查场内对照。不能仅凭一处接缝或单张 SEM 认定整片合格；异常应结合设备、胶处理与测量记录排查。MN Fab Hub recommends facility review of whether critical features can avoid boundaries. Where crossing is required, include representative devices and boundary test patterns, and retain field coordinates and exposure settings. Inspect displacement, gaps, overlaps and dimensional changes alongside within-field controls. One seam or SEM image cannot qualify a whole sample; review tool, resist-processing and measurement records together.

验收报告与下一步Acceptance report and next step

建议事先约定抽检位置、数量、偏差定义、测量方法及通过标准。报告关联版图坐标、写场边界、实测偏差、缺陷图像和样品编号；后续转移可能改变尺寸，应另行约定复测。报价区分版图整理、试片曝光、边界检测及迭代轮次，资料齐备后确认平台匹配、周期和费用。Agree sampling locations and count, deviation definitions, measurement methods and passing criteria in advance. Link results to layout coordinates, field boundaries, measured deviations, defect images and sample IDs. Agree further checks after pattern transfer. Itemize data preparation, pilot exposure, boundary inspection and iteration rounds before confirming facility, schedule and cost.
