In high-tech fields such as semiconductors, precision manufacturing, and new materials, the microstructure of the material surface directly determines the performance and reliability of the product. To precisely control every link from research and development to production, a reliable and highly adaptable oneIndustrial-grade 3D profilometerOf vital importance. So, how to choose a professional manufacturer that can not only provide precision instruments but also have a deep understanding of industry applications? This article will provide you with a detailed analysis.
With the miniaturization of product design and the complexity of manufacturing processes, traditional detection methods have become inadequate to meet the demands. Industrial-grade 3D profilometers can obtain the three-dimensional topography of the sample surface in a non-contact manner. Whether it is nanometer-level roughness, micrometer-level step height, or large-area warpage and stress, they can all achieve rapid and high-precision measurements. It is like the "eyes" of scientific research and industrial production, helping us to see and quantify the microscopic world that determines the success or failure of a product.
Most of the mainstream industrial-grade 3D profilometers on the market adopt white light interference technology. The principle is to utilize the characteristics of white light interference and precisely calculate the height of each point on the sample surface by analyzing the interference fringes. The advantage of this technology lies in its high measurement accuracy, fast speed and no damage to the sample.
Take the KLA Profile 3D white light interference profilometer represented by Unicom Technology Co., LTD. (Yiying Technology) as an example. It combines two technologies: vertical scanning interference (WLI) and phase interference (PSI).
WLI mode: Suitable for measuring step thickness, film thickness and texture from 50nm to 10mm, with a wide range.
PSI mode: Specializing in ultra-smooth surfaces ranging from 0 to 3μm, its RMS repeatability can reach 0.1nm, providing a reliable guarantee for ultra-precision machining and optical component inspection.
When choosing a suitable industrial-grade 3D profilometer, one should not only focus on the promotion but also pay attention to the core parameters. The following are three key aspects that need to be examined:
Accuracy and repeatability: These are the core lifeblood of a profilometer. High-precision equipment can ensure the authenticity and reliability of measurement results. For instance, the step height accuracy of KLA Profilm3D can reach 0.7%, and the RMS repeatability (in WLI mode) is 1.0nm, ensuring that every measurement is stable and reliable.
Measurement capability and adaptability: The key lies in whether one can handle complex samples. The field of view range, the travel of the sample stage, and the adaptability to different materials (from 0.05% to 100% reflectivity) all test the design of the equipment. The Profilm3D can provide a 2mm field of view with only a 10x objective lens and is equipped with a 100mm automatic XY sample stage and a 4-hole objective lens turntable, achieving a balance between a wide field of view and high efficiency.
Software and analysis functions: Hardware acquires data, and software mines value. A set of intuitive and powerful software enables users to easily obtain 2D/3D parameters such as roughness, step height, and stress, and supports international standards like ISO25178, providing a solid basis for data analysis.
An outstanding industrial-grade 3D profilometer manufacturer must have products capable of "cross-border" operations to meet diverse inspection requirements:
Semiconductor industry: Used for step height measurement of Die Saw and PAD on wafers, as well as surface roughness and defect detection after CMP process.
New material research and development: Precisely characterize film stress and coating thickness, and analyze the relationship between the microstructure and properties of materials.
Precision Machinery and Optics: Measuring MEMS microstructures, surface shape errors of optical lenses, surface textures and wear conditions of precision components.
Universities and research: Provide high-precision topography characterization tools for research in fields such as materials science, physics, and biology.
