Today, with the rapid development of high-tech industries, the precise preparation and quality control of thin film materials have become the core determinants of product performance. Whether it is a nano-scale photoresist coating or a micron-scale waterproof coating, the slightest deviation in their thickness may directly lead to product failure. Therefore, high precisionFilm thickness measuring instrumentIt has evolved from a research tool in the laboratory to an indispensable "sharp eye" in industrial production lines and quality inspection processes.
For instance, in semiconductor manufacturing, the uniformity of the thickness of dielectric films such as silicon oxide and silicon nitride is directly related to the electrical performance of the chips. In the field of consumer electronics, the thickness control of the hardened layer on the back cover of mobile phones and the packaging film of OLED displays is a key factor affecting the durability and display effect of the products. Without reliable film thickness gauges, these high-end manufacturing processes would be like "the blind men touching an elephant", making it difficult to ensure batch consistency and product yield.
Mainstream high-precision devices, such as the Filmetrics series of film thickness gauges represented by Unicon Technology, adopt the spectral reflection measurement principle. When a broad-spectrum white light beam is projected onto the surface of a thin film, it will generate reflected light at the upper and lower interfaces of the film and cause interference. By precisely analyzing the oscillation frequency and intensity of the reflection spectrum, the instrument can not only accurately calculate the film thickness (ranging from 1 nanometer to 3 millimeters), but also simultaneously obtain key optical constants such as the refractive index and reflectance of the material. This non-contact, full-spectrum measurement method ensures the comprehensiveness and extremely high accuracy of the data.
Universal and efficient choice: Filmetrics F20 Series: As a widely used desktop model, the F20 series is easy to install. Just connect it to your computer and you can get results within seconds. It is applicable to the vast majority of smooth and semi-transparent film materials, ranging from semiconductor film layers, photoresists to waterproof coatings, PI films, etc., and its application fields are extremely extensive.
Mapping Expert: Filmetrics F50 Series: For scenarios where the uniformity of film thickness needs to be analyzed, the F50 series supports automatic multi-point measurement and can quickly generate two-dimensional or three-dimensional thickness distribution maps. Its measurement speed can reach 2 points per second, and it can support samples with a maximum diameter of 450 millimeters. It is a powerful tool for quality inspection of large-area samples such as liquid crystal panels and wafer coating.
Exclusive application models: For special processes, there are also series of exclusive models. For instance, the F40 series features a 1-micron ultra-small spot, making it suitable for measuring tiny areas such as patterned wafers. The F10 series has been specifically optimized for special coatings such as the hardening layer of car lamps and the optical anti-reflection layer.
Professional solution support: The company's core team has a profound technical background and can provide targeted measurement solutions and process support based on the specific materials, processes and application challenges of customers, rather than simply selling equipment.
Full-process standardized service: From demand communication, free sample testing, solution determination to installation training and after-sales support, Unicon has established a nine-step standard operation process to ensure standardized service and prompt response.
National service network: With the headquarters in Shanghai as the center, it has branches in Dongguan, Tianjin, Chengdu, Suzhou and other places, forming a service network covering the whole country, ensuring localized and timely technical support.
