Paper Abstract

In a 2009 analysis of microbridging defectivity, a design of experiment methodology was used to show the effect of filtration parameters on microbridging defectivity, specifically focusing on filter retention rating, filter media and design, filtration rate, and controlled filtration pressure. In that analysis it was shown that different filter architectures provide the most effective filtration of microbridging and that different filter architectures show different levels of microbridging defects even when optimally tuned. Ultimately, filter choice and filtration setup matter in removal of microbridging defects. In the new analysis, a similar approach was taken with additional filter types. However, in the new study the retention rating of the filters was kept constant at 10nm while other filter parameters were varied, including membrane material and design. This study will show the specific effect of the membrane material and design on microbridging defectivity in addition to the effects of filtration setup.
