LiquiPro™ MI Disposable Capsule Filters Features

  • Ultra-clean filter design. Filter design, materials selection and UHP decontamination procedure are optimised to eliminate shedding and extractables to ensure reliable downstream cleanliness.
  • LiquiPro™ MI provide excellent chemical compatibility to make these filters ideal for point of-use photochemical filtration applications, including a broad range of photoresists and solvent.
  • Designed for the removal of micro gel, soft gel and particles present in most advanced photoresist systems. Eliminates pre-wetting and reduces downtime.
  • Advanced photoresist system consists of typically of solvent, photo acid generator (PAG), acid quenchers, additives and surfactants. Pre-wetting is not required.
  • LiquiPro™ MI D PN series helps to eliminate micro-bridging defects in photoresist and cone defects in the anti-reflective coatings.
  • This disposable series uses the highest quality PES membrane which is hydrophilic to positive developers such as TMAH and DI to eliminate the formation of bubbles and micro-bubbles during the spin rinse process
