光刻胶旋涂膜厚Photoresist spin-coating thickness

先把目标胶厚和测量位置说清楚，再选胶型与试片条件。Define target thickness and measurement locations before selecting resist and pilot settings.

适合什么需求Suitable projects

适用于接触式光刻、电子束曝光、刻蚀掩膜、金属剥离和 SU-8 厚胶结构的涂胶试片或膜厚异常排查。薄胶与厚胶、多层胶与有台阶基底应分别评估；微纳Hub可先整理输入，再与接收平台确认可用胶型和设备。For coating pilots and thickness troubleshooting in UV lithography, EBL, etch masks, lift-off and SU-8 structures. Evaluate thin, thick, multilayer and topographic substrates separately; MN Fab Hub helps prepare inputs for facility review.

转速曲线只是起点Spin curves are a starting point

MicroChemicals 的旋涂说明指出膜厚受转速、时间、胶液黏度和溶剂挥发影响；厚胶在旋涂与软烘后的厚度变化尤其需要记录。[1] Kayaku 的 SU-8 3000 资料也按胶型和转速提供膜厚曲线。[2] 产品曲线不能直接当作不同基底和设备上的交付保证。MicroChemicals describes the effects of spin speed, time, viscosity and solvent loss on film thickness, including further changes around soft bake. [1] Kayaku provides resist-specific spin curves for SU-8 3000. [2] Supplier curves are starting points, not delivery guarantees on a different tool or substrate.

询价与送样资料Inputs for quotation and samples

请提供基底材料、尺寸和数量，表面已有膜层或台阶，目标胶型、正负胶属性、目标厚度及容差，图形最小尺寸和后续曝光、刻蚀或剥离路线。若已有试片，附胶液批次、保存条件、滴胶量、加速度、转速与时间、软烘程序、膜厚点位和原始数据。未知项标为待确认。Provide substrate material, size and count, existing films or steps, resist type and tone, target thickness and tolerance, minimum feature size and downstream process. For prior trials, include resist lot and storage, dispense volume, acceleration, speed and duration, soft bake, measurement locations and raw data. Mark unknowns clearly.

常见风险与试片设计Risks and pilot design

基底润湿性、边缘堆胶、台阶覆盖、颗粒、针孔和软烘后的厚度变化，都可能使中心单点测量失真。建议用代表性基底先做少量条件试片，固定测量方法与排除边缘区域的规则；边缘去胶另见 EBR 专题。不要仅凭名义转速推定整片均匀性。Wetting, edge beads, topography, particles, pinholes and post-bake thinning can make a single center reading misleading. Pilot on representative substrates with a fixed metrology plan and edge exclusion rule. See the EBR guide for edge handling. Nominal speed alone does not establish whole-wafer uniformity.

验收与下一步Acceptance and next step

事先约定软烘后测厚时间、仪器、点位图、平均值、片内范围和缺陷判据；多层胶分别记录层序与每层厚度。报价区分试片条件、样品数、检测点数和迭代轮次。资料齐备后由接收平台确认工艺窗口、周期和费用。Agree on post-bake timing, metrology tool, point map, mean thickness, within-sample range and defect criteria. Record layer order and individual thicknesses for multilayer stacks. Itemize pilot conditions, samples, measurements and iterations; the receiving facility then confirms process window, lead time and cost.
