In the production process of the semiconductor industry, it is necessary to detect the concentration of the stripping solution, hydrogen peroxide, and hydrofluoric acid solution. Although the solution concentration monitoring is not a key process, it is an indispensable part.

In the semiconductor industry, the monitoring of the concentration of hydrofluoric acid (or other) solutions will affect the quality of the chip, so the use of online refractometers for process control can greatly improve the pass rate of products.
