Particle counts at 20 nm
Yield-limiting particles are far below the detection threshold of conventional instrumentation, let alone conventional filtration.
Ultra-high-purity filtration for wet process, gas delivery and sub-fab abatement in advanced fabs.
The constraint
At advanced process nodes, a single particle in the wrong place destroys a die. Filtration is not a utility here — it is a direct determinant of yield and therefore of the fab's economics.
Standards we work to
Yield-limiting particles are far below the detection threshold of conventional instrumentation, let alone conventional filtration.
Filter materials must contribute no measurable metallic ions to process chemistry at parts-per-trillion sensitivity.
Fabs run dozens of aggressive chemistries requiring an all-fluoropolymer flow path throughout.
The change-out procedure itself is a contamination event and must be engineered as carefully as the filter.
Next step
Our applications engineers work to the standards listed above every week. You will not be explaining your industry from first principles.
