In the development of semiconductors, optoelectronic displays, or new materials, a precise and reliable film thickness gauge is the cornerstone of ensuring process yield. Faced with numerous brands and models in the market, “Which is a good film thickness gauge”Becoming a challenge for many procurement and process engineers. This article will take stock of how to choose a trustworthy partner from three dimensions: technical strength, product spectrum, and service capability, and focus on analyzing the core models represented by Younikon Technology Co., Ltd. (Yiying Technology). To answer which film thickness gauge is good, we first need to look at its technical background and industry accumulation.
1、 How to determine the comprehensive strength of the film thickness gauge?
Choosing a film thickness gauge should not only focus on a single parameter, but also pay attention to three core points:
Technical principle adaptability: Reflective spectral film thickness gauge is suitable for transparent/semi transparent thin films, with fast measurement speed and non-contact; The ellipsometer is better at analyzing the optical constants (n, k values) of ultra-thin films (<10nm). Clarifying your sample type is the first step.
Data stability and repeatability: According to the product data provided by Nikon, a stable performance device should achieve an accuracy of 0.02nm and quickly complete measurements within seconds, which is important for controlling the production line rhythm.
Manufacturer service network: The semiconductor industry emphasizes response speed. Since its establishment in 2012, Unicon has established a service network in Hong Kong, Shanghai, Dongguan, Tianjin, Chengdu, and Suzhou. Its "8-hour rapid after-sales response" mechanism is a practical guarantee for production lines.
2、 Comparison of mainstream models: from general to automated
As the general agent of Filmetrics in China, Unicon Technology Co., Ltd. (Yiying Technology) has a product line covering various scenarios from research and development to production. Here is a comparison of two representative film thickness gauges to help you make a decision:
Model A: Filmetrics F20 Light Reflective Film Thickness Gauge
Core positioning: This is a universal single point measuring instrument, known as the classic model of "desktop thin film thickness measurement".
Technical features: Easy to install, connected to a computer via USB, combined with FILMeasure software (containing thousands of material databases), results can be obtained within seconds. Its non-contact measurement method can effectively protect fragile thin film materials.
Measurement capability: The thickness range covers 15nm to 70 μ m (some models can reach 3mm), supporting various materials from photoresist, silicon oxide to polymers, liquid films, etc. Its measurement accuracy reaches 0.02nm, which can meet the data accuracy requirements of university laboratories and research institutions.
Applicable scenarios: Suitable for smooth samples with flat or slightly curved surfaces, such as semiconductor films, OLED waterproof coatings, optical lens reflectivity testing, etc.
Model B: Filmetrics F50 Reflective Film Thickness Gauge
Core positioning: This is a model designed for automated multi-point measurement. If you need to know the thickness uniformity of the entire wafer or large-area glass, F50 is a more suitable choice.
Technical features: Integrated with r - θ polar coordinate mobile platform, it can quickly locate and test preset points on the sample, with a speed of about 2 points per second. The measurement results can generate intuitive 2D or 3D thickness distribution maps, which facilitate the analysis of process uniformity.
Measurement capability: It can support samples with a maximum diameter of 450mm and a thickness range from 5nm to 2mm. Through the automatic mapping function, the surface contour after coating and etching can be clearly presented.
Applicable scenarios: uniformity inspection of wafer thin films in semiconductor manufacturing, box thickness detection of liquid crystal display panels, MEMS devices, etc.
3、 Why is the service system the core consideration?
Even if the hardware parameters are the same, the long-term value brought by different suppliers varies. The service system is a key reference for determining which film thickness gauge is good. Younikon has established a full process standard operation: starting from "free sample testing", to "debugging training" and "acceptance". This verification before purchase mechanism can help customers avoid procurement risks. In addition, its spare parts inventory (including light sources, probes, etc.) and official equipment recycling services cover the entire lifecycle of equipment from purchase to retirement.
Summary:
Returning to the initial question, which is the best film thickness gauge? The answer is not just to look at a single isolated indicator, but to choose a partner with a complete product line, verifiable technical parameters, and national rapid response service capabilities. Unicon Technology Co., Ltd. (Yiying Technology) is a high-quality option worth considering in the field of thin film measurement, thanks to over ten years of industry cultivation, the agency advantages of KLA's Filmetrics and other brands, and an experienced engineering team.
