The XpressKleen G2 XP 5 nm filter represents a significant advance in the development of microporous PTFE membranes to meet the severe contamination control challenges that exist below the 14 nm manufacturing node. Pall Corporation’s material science team of scientists and engineers has created a new filter morphology unlike current designs using newly developed proprietary PTFE membrane manufacturing technology.
The revolutionary design provides unparalleled control of critical size particles greater than 5 nm combined with a new standard of device cleanliness and purity that guarantees less than 500 ppt of total metal ion extractables per single length filter1. Proprietary advanced cleaning methods produce a filter with ultra-low levels of organics, NVR, and transient surface borne particles.
Every aspect of the XpressKleen XP 5 nm filter, from the PTFE resin to the final package, is designed, controlled, and manufactured to deliver unparalleled and elevated performance that is consistent, repeatable, and a new standard in sub 7 nm particle retention.
The unique combination of low differential pressure and measured retention at 5 nm makes the filter suitable for use from the point of supply (POS) to the point of process (POP), in bulk delivery, recirculating batch filtration, and in single wafer applications.The XpressKleen 5 nm filter is an integral part of a contamination control system that enables particle and purity defect levels needed for 10 nm and finer manufacturing.
The nondewetting XpressKleen G2 filter is qualified for use in aggressive high temperature cleaning chemistries like SPM, H3PO4; concentrated chemicals like NH4OH, HCl, H2SO4, H2O2; IPA and other solvents; high ppm DIO3, and aqueous chemistries such as SC1 and SC2.
