CYCLOTENE™ 4000 Series (Immersion processing)

The CYCLOTENE™ 4000 Series Advanced Electronics Resins are i-line-, g-line-, and broad band-sensitive photopolymers that have been developed for use as dielectrics in thin film microelectronics applications.


Pack Sizes and Applications:



  • Dielectric Layers
  • These polymers are derived from B-staged bisbenzocyclobutene (BCB) chemistry and have final film properties similar to the dry etchable 3000 series.
  • They have excellent dielectric properties
  • They perform well when working with photo-defined BCB resin i-Line and multi-wave exposure
