Adsorbent and Chemical Filter

Research Area Overview

Research Direction

Semiconductor and display industries’s integration technology is improving with advanced precision manufacturing process. For this, the control of AMC,*—i.e. microparticles and gaseous components in cleanrooms—is required. ECOPROHN provides the solution needed for electronic product production cleanrooms and the improvement of indoor air quality (IAQ) with research on high-functional adsorbents and chemical filters.

* AMC stands for airborne molecular contamination and refers to VOCs, acid/alkaline gases, ozone, etc.

Major Research Areas

  • Development of high-functional adsorbents and catalysts
  • Development of chemical AMC purification filters for semiconductor and display fabrication and manufacturing equipment
  • Development of technologies to remove bad odors and harmful gases
  • Development of filters to improve indoor air quality (IAQ)
