Abstract
The cleaning process to remove small particles, ions, and other polluted sources is one of the major parts in the recent semiconductor industry because it can cause fatal errors on the quality of the final products. According to the other reports, the major factors of bath's fluid motion are the cleaning method, nozzle, the geometry (of bath, guide and wafer), and the position (of guide and wafer). So to enhance cleaning efficiency in the bath, these factors must be controlled. The purpose of this study is to analyze and visualize fluid motion in the cleaning bath as basic data for designing the nozzle system and finding the process control parameters. For that, we used the general CFD code FLUENT.
