The constraint

Contamination control at the node.

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

  • SEMI F57
  • SEMI C79
  • ISO 14644
  • ASTM D5127
  • IEST-RP-CC021

Particle counts at 20 nm

Yield-limiting particles are far below the detection threshold of conventional instrumentation, let alone conventional filtration.

Metallic ion contribution

Filter materials must contribute no measurable metallic ions to process chemistry at parts-per-trillion sensitivity.

Chemical compatibility breadth

Fabs run dozens of aggressive chemistries requiring an all-fluoropolymer flow path throughout.

Change-out contamination risk

The change-out procedure itself is a contamination event and must be engineered as carefully as the filter.
