Water Filter With Active Carbon

Activated carbon filters are critical in the semiconductor wafer industry for providinga clean and controlled environment during the manufacturing process. Volatileorganic compounds (VOCs) and other air contaminants can adversely affect thequality and yield of semiconductor devices. Therefore, removal of AMC is critical.

One of the major uses of activated carbon filters in the semiconductor industry is forcleanroom air filtration. These filters are designed to remove AMCs such as acids,alkalis, condensates and dopants from process air The filter media can be activatedcarbon which can effectively adsorb and remove a wide range of contaminants toensure the clean indoor air purity.

Isopropyl alcohol (IPA) is a widely used solvent in the cleaning process ofsemiconductor wafers and might be a major source of organic contaminants.Organic acid modified activated carbon filters were developed for the removal ofisopropyl alcohol (IPA) from clean room air. Modification of activated carbon withorganic acids (e.g. oxalic acid) improves the adsorption of IPA and the overallperformance of the filter.

In the semiconductor wafer manufacturing industry, activated carbon filters areutilised to help maintain the cleanliness and integrity of the manufacturing process.These filters help to reduce defects and yield loss in semiconductor devices byremoving volatile AMC. They are critical to guarantee the quality and reliability of theend product.
