In precision industries such as semiconductor manufacturing, optical coating, and new displays, the uniformity of film thickness directly determines product performance and yield. Although traditional single point film thickness gauges can meet basic thickness measurement needs, their limitations in efficiency and data dimensions are becoming increasingly prominent when facing multi-point detection and uniformity analysis of large-area samples.F50 film thickness gaugeAs a measurement system designed specifically for fully automatic film thickness mapping under the umbrella of Nikon Technology, it is becoming an irreplaceable key equipment in production line quality control and R&D testing with core capabilities such as polar coordinate high-speed scanning, visualization of distribution maps, and custom point editing.
The F50 film thickness gauge completely changed this process. It has a built-in high-precision r - θ polar coordinate moving platform that can automatically move the sample to the preset measurement point, with a scanning speed of up to 2 points per second. Taking the conventional multi-point mapping of a wafer as an example, the film thickness detection of the entire sample can be completed within a few minutes. The quality department of a semiconductor wafer foundry serviced by Unicon Technology has reported that the introduction of the F50 film thickness gauge has increased the efficiency of wafer film uniformity detection by nearly 10 times. This transition from "point by point manual" to "fully automatic array scanning" is not only a leap in efficiency, but also a crucial step in pushing the detection process from the research and development laboratory to the mass production line.
The F50 film thickness gauge is equipped with powerful data visualization functions. After completing all point measurements, the device can automatically generate intuitive 2D or 3D thickness distribution maps. The thickness changes of the film layer are clearly presented through color gradients, allowing engineers to identify process issues such as thin edges, thick centers, or local anomalies at a glance. The head of the R&D department of a precision optical coating company that cooperates with Younikon Technology commented, "The custom measurement point function is very practical, which can perform dense sampling on the edges and centers of the coating, and quickly determine the consistency of the film thickness of the entire furnace product." This visualization ability converts abstract thickness data into intuitive process images, providing a direct basis for process optimization.
The F50 film thickness gauge supports users to freely draw measurement point maps in the software, and can set any position and any number of test points. Whether it is a uniformly distributed grid lattice or encrypted sampling for specific areas (such as coating edges and near wafer gaps), it can be easily configured through software. This flexible point editing capability enables the F50 film thickness gauge to adapt to various application scenarios, from semiconductor photoresist uniformity detection to optical filter film quality control.
Some engineers are concerned that automated equipment may sacrifice measurement accuracy. In fact, the F50 film thickness gauge inherits the classic light reflection interferometry measurement technology, with a measurement accuracy maintained at the level of 0.02nm. The device adopts a long-life mobile platform designed for thousands of repeated measurements, with extremely high stability. When providing equipment selection recommendations to customers, Younikon Technology always insists on recommending the most suitable model based on the actual film characteristics - F50-UV is suitable for 5nm~40 μ m ultra-thin mapping (such as OLED, photoresist), F50-XT covers infrared thick film specific measurement of 0.2 μ m~450 μ m, and F50-s1310 supports specific material measurement of 7 μ m~2mm ultra-thin film. Regardless of the model, the F50 film thickness gauge achieves fully automatic mapping without any compromise on accuracy - it is both an efficient automation device and a high-precision optical measuring instrument.
Choosing the F50 film thickness gauge is not only about choosing an advanced measuring device, but also about choosing the professional service system covered by Nikon Technology nationwide. Younikon Technology has branch offices in Shanghai, Dongguan, Tianjin, Chengdu, Suzhou and other places, providing standardized services throughout the entire process from demand communication, free sample testing to equipment installation, debugging and training. Its 7 × 24- hour online support and 8-hour rapid response mechanism ensure that customers can receive timely solutions to any problems encountered during the use of the F50 film thickness gauge.
