CMP Filters

Accumate^® E series slurry filters

• NexPore Accumate E series graded density filters are constructed of wrapped Nano Melt Blown (NMB) polypropylene media, have a retention gradient along their depth.
• The filter media was engineered to be with a sharp retention cut-off that closely aligns to the size distribution of undesired particles to be removed.
• This sharp removal cut-off will not alter percent solids or remove desired particles thus preserving the polishing characteristics of the slurry.

• Accumate^® E Series Filters
• PP NMB + PP Hardware
• Micron: 1, 3, 5, 7, 9, 11, 16

CMP Filters

Accumate^® P series slurry filters

• NexPore Accumate P series filters are disposable capsules, combine 2 construction types the depth and the pleated together to significantly increase the filtering area.
• This unique media combination greatly increases the area, so this capsule can also be used with tighter retention ratings, and enables filtration in chemical delivery system applications where a higher particle loading capacity is required.
• The filter media is Nano Melt Blown (NMB) with improved media porosity that addresses the problems associated with flow rate reductions during filtration. 
• The high particle holding capacity resulting from the special designed pleated plus depth media construction and the use of NMB media also extends filter life, reducing the overall cost of ownership in the filtration process.

• Micron: 0.1, 0.3, 0.5, 0.7, 1. 3, etc.

ECP filters

Aquapure^® filters

• NexPore Aquapure filters use highly-asymmetric PES membrane with ‘philic character. The more elegant approach is to modify the structure of the filter, so there are more places on the surface of the filter for particles to be trapped without blocking the pores. This technique uses an asymmetric membrane structure in which the upstream surface of the filter has larger pores than the downstream surface. 
• Our Aquapure series filters are designed to solve one of the major problems in electrochemical copper deposition: the formation of particles in gel-like nature significantly increases their ability to plug the filters.
• The entire materials of our Aquapure filter construction do not interact with plating chemistry and the hydrophilic character of PES ensures minimizing the microbubble generation and resulting in fastest start up times, the user does not need to pre-wet the filter in advance.
