Accurate measurement of film thickness is a key link in quality control and process optimization in high-tech fields such as semiconductor manufacturing, optical coating, and new material research and development.Film thickness testerAs a core measurement tool, its selection and use directly affect research and development efficiency and product performance. This article will provide a beginner's system analysis of the working principle, mainstream equipment characteristics, and quick start guide of the film thickness tester, helping you easily get started and measure efficiently.
This non-contact measurement method will not damage the thin film, especially suitable for sensitive materials such as photoresist, polymers, and biological coatings. At present, the mainstream film thickness testers on the market mainly use white light reflectance spectroscopy, which can complete single or multi-point measurements within seconds, combining high accuracy and efficiency.
通用入门首选：Filmetrics F20系列 这款桌面式膜厚测试仪以其便捷安装（USB即插即用）和快速测量（数秒出结果）著称。它适用于大多数光滑、半透明或低吸收薄膜，厚度测量范围从1纳米到3毫米，垂直分辨率达纳米级。无论是半导体膜层（如SiNx、TiO2）、OLED防水涂层，还是光学镀膜、生物医学薄膜，F20都能稳定应对，是实验室基础测量的可靠工具。
自动测绘进阶：Filmetrics F50系列 如果你需要分析薄膜厚度的均匀性，F50系列是更优选择。它具备自动多点Mapping功能，可快速生成样品的厚度分布图，测量速度高达每秒2个点。其光斑最小可至10微米，能适配最大直径450毫米的样品（特殊型号可扩展至590毫米×550毫米），非常适合半导体晶圆、大尺寸显示面板等需要面分析的应用场景。
微区与在线监测专用型号 针对特殊需求，优尼康还提供丰富型号：如F40系列配备显微物镜，光斑小至1微米，专为图案化晶圆等微区测量设计；F54-XY-200支持12英寸晶圆全自动测量；F32系列适用于在线镀膜工艺的实时厚度监控。这些产品体现了膜厚测试仪在细分场景下的高度适配性。
Clarify measurement requirements: Firstly, determine the type of film to be tested (transparent, semi transparent, metallic, etc.), approximate thickness range, sample size, and state (solid, liquid, gas). Do you need single point measurement or thickness distribution map? This helps in selecting the appropriate instrument model.
Sample preparation and placement: Ensure that the surface of the sample is clean and flat. For liquids or flexible films, a dedicated sample stage or carrier should be used for fixation. Place the sample steadily on the instrument sample table, avoiding tilting or shaking.
Software operation and measurement: Taking Filmetrics equipment as an example, start the dedicated FILMeasure software. The software has a built-in database of thousands of materials, and users can choose or input the optical constants of the materials. By using a real-time camera to locate measurement points and clicking on the measurement button, thickness, refractive index, and other results can be directly read on the interface within seconds. Users of the F50 series can also customize measurement points and automatically generate thickness distribution maps using the FILMaper software.
Result analysis and validation: The measurement data provided by the instrument usually includes thickness values, uniformity statistics (such as maximum, minimum, mean, standard deviation), and spectral fitting curves. Novices can verify the accuracy of the instrument and establish measurement confidence by measuring standard plates of known thickness.
Product and Technical Support: As the general agent of Filmetrics in China, we also have deep cooperation with internationally renowned brands such as KLA and HORIBA to ensure equipment quality and technology. The product line comprehensively covers thickness measurement needs from nanometer to millimeter level.
